Description

FIELD OF THE INVENTION

The invention relates to methods and systems that make it possible to control the mechanical properties of components before their connection and installation. More specifically, the scope of the invention relates to tracking, monitoring and control of pipes, casing, liners, tubing and pipelines that are used for drilling and constructing wells. More specifically, the invention relates to methods for tracking, monitoring and controlling these components throughout their transportation to wells. The scope of the invention also relates to the marking of pipes for their inspection.

BACKGROUND OF THE INVENTION

Industrial objects such as pipes and pipelines that are to be inserted into the well are subject to visual inspection and some inspection, which must be recorded in the computer. The goal is to provide on-site assembly of a production structure that is built piecemeal in an environment where significant constraints exist.

One difficulty encountered in well operations is that the assembly of the production structure may involve many changes in the design of the elements to be inserted or modifications to the elements themselves. It involves rejecting pipes and increasing relocations at different sites, for example to repair a pipe or to replace a pipe element.

Another difficulty remains when calculating some well parameters, such as the amount of drilling fluid increment or the volume of cement in the well. These values are updated each time an element is introduced into the well to ensure assembly within the well's constraints. These values can be calculated based on information related to the next pipe to be inserted and information related to the production structure assembly that is already in the well. Currently, the operator inspects the pipe, enters data related to the pipe into the computer, and records specific values such as diameter, pipe length, etc., for the purpose of calculating new values for these well parameters. Some input errors may occur and this operation is time-consuming due to the manual process that must be carried out between visual inspection and generation of new well parameter values.

Pipe tagging solutions allow the inspection of specified pipes for inventory purposes or to track pipes while being transported between two different locations.

GB 201317246 discloses a method for checking identification information, etc., of a pipe containing a tag. The label contains all the information about the tube and the company that manufactured the tube. However, this document does not disclose a method for ensuring that the pipe contains certain modifications that can be monitored at all stages of its transportation down to the well to facilitate visual inspection.

WO 2009128999 discloses a method for updating data in a well control system. This document describes the implemented means for updating the central database, but does not disclose the monitoring of certain parameters during the insertion of pipes into the well to control the production structure and certain parameters of the well.

US 2009121895 also describes a solution for reading pipe information via a tag. But this document does not disclose a solution in which information about the production structure or well can be generated and updated based on data read from the pipe.

GB 2472929 discloses a solution in which information about the mechanical characteristics of a pipe can be accessed by reading a mark on said pipe. The method is aimed at combining information about pipes and their location. This document does not describe how pipe information can be used to control pipe insertion into a well.

US 8463664 also discloses a method for identifying a pipe and its location. The method discloses planning-related data that can be used to facilitate a customer order. This document does not disclose a method in which pipe information is used with other elements of the same production structure as they are introduced into the well.

Therefore, there is a need for a method that allows the pipe to be dynamically monitored as it is about to be inserted into the well.

There is a need for a method that provides control of pipes that are to be inserted into a well while maintaining safe operations with the pipes and the production structure being built. There is a need for a method that facilitates obtaining pipe information and providing real-time correspondence to certain well parameter values.

SUMMARY OF THE INVENTION

According to one aspect, the invention relates to a method for monitoring the condition of a first pipe, wherein said first pipe is intended to be connected to a production structure, wherein a first server manages a digital descriptor of the first pipe, wherein said digital descriptor comprises a first set of data stored in at least a first storage device, wherein said first data set contains at least:

one tracking code for the first pipe; and

completion state and planning state,

this method also includes:

authenticating the first pipe by capturing the tracking code of the first pipe;

generating a first request for the first server from a computer located next to the first pipe;

obtaining an identification number to create an inventory state of the first pipe;

obtaining a first completion status value of the first pipe;

obtaining a second scheduling state value of the first pipe;

generating at least one warning when the first or second value is equal to the specified status value.

One advantage is the collection of data on the various conditions of the pipe, which can be accessed by a computer at any time throughout the entire life of the pipe. Among the various states, the invention relates in particular to an inventory state, a completion state, and a planning state for monitoring said pipe when it is introduced into a well. The invention makes it possible to control whether the pipe number in sequence matches the previous elements that were introduced into the well. The invention makes it possible to check the mechanical characteristics of said pipe taking into account each change in the overall transportation process.

Said warning may be a message or icon displayed on the user interface. The warning may be due to operator validation through the user interface.

In one embodiment, the first data set contains at least:

the first subclass of geometric data containing at least one of the following:

outside diameter; inner diameter; weight; steel grade; bore diameter; wall thickness; minimum wall thickness; working length; material standard;

a second subclass of connection component data comprising at least one of the following:

connection type; the total length of the joint with another interface component;

a third subclass of workflow data containing at least one of the following:

pipe tracking code; coupling tracking code; serial number; contract number indicating the location of the wells; manufacturer's name; date of manufacture;

a fourth subclass of work order data containing at least one of the following:

link to work assignment; serial number in the work order.

One advantage is that it gives the operator access to different types of data. This allows the operator to control, for example, that one pipe modification meets the overall constraints of the production structure in the well. This feature allows you to reduce errors when inserting the pipe into the well.

In one embodiment, the completion status is set to:

having at least one value in specified data fields of the first, second and third data subclasses of the first data set; and/or

the specific value of the completion status field in the first data set.

Completion status monitoring allows you to check whether the pipe is compatible with the elements it comes into direct contact with. This ensures that the entire mining structure contains elements that are subject to injection.

In one embodiment, the scheduling state is set to:

having at least one value in specified data fields of the fourth data subclass of the first data set; and/or

specific value of the characteristic of the fourth data subclass.

One benefit is to ensure that each pipe that needs to be inserted into the well is properly planned. This allows you to collect data from each pipe in a final list with data from the work order, which contains the planning sequence for constructing the production structure. The benefit is to be sure that the selected well pipe is the pipe specified in the work order data table. This check is aimed at reducing errors when selecting pipes for insertion into the well.

In one embodiment, the first set of data contains a reference to a work order from a work order data table, wherein said work order data table contains a sequence number, wherein the method of the invention also includes:

generating a second request for the first server from a computer located next to the first pipe;

retrieving a work order data table containing a second set of data relating to a plurality of pipes, said plurality of pipes comprising a first pipe;

obtaining the serial number of the first pipe from the first data set;

comparing the serial number of the first pipe in the specified work order data table with the serial number:

another pipe of the same work order data table;

wherein the first pipe is recorded in the first data set;

generates a warning when the comparison of both sequence numbers is below or above a specified threshold.

One advantage is to control the order in which each element is introduced into the well according to a specified sequence. Control can be done at any time. When the pipe is inserted into the hole, the mark can be automatically read by the camera to perform a final check. This system makes it possible to enhance the compliance of the mining structure with the constraints of the work order data table.

In one embodiment, the first set of data contains at least a fourth geometric feature value of said pipe, wherein said method determines the geometric state, wherein said method includes:

obtaining the value of the first geometric feature through the user interface;

comparing a fourth geometric feature value contained in the first data set with the obtained first geometric feature value of the first pipe;

generating a third warning when the comparison of two fourth values is above or below a specified threshold.

One advantage is to calculate the mechanical compliance of each pipe inserted into the well using reference values. Comparison of geometric or design parameters also allows one to calculate and predict some well characteristics that may change with the introduction of a new pipe, for example, the amount of drilling fluid increment.

In one embodiment:

when the first geometric value is the total length of the first pipe, wherein the method determines the state of the length, the method includes the following steps:

automatic calculation of the total length of pipes connected to the production structure, the serial number of which is lower than the serial number of the first pipe;

comparing the calculated cumulative length with the reference value recorded in the workflow data;

generates an alert when the specified comparison is above or below a specified threshold.

In one embodiment:

when the first geometric value is the internal diameter of the first pipe, the method determining the state of the drilling fluid, the method includes the following steps:

automatic calculation of the estimated value of drilling mud increment;

comparison of the estimated mud growth rate with the expected mud growth stored in the workflow data;

generates an alert when the specified comparison is above or below a specified threshold.

In one embodiment:

when the first geometric value is the outer diameter of the first pipe, the method determining the condition of the cement, the method includes the following step:

automatic calculation of the estimated volume of cement to be introduced;

Comparing the estimated cement volume estimate with the expected cement volume stored in the workflow data;

generates an alert when the specified comparison is above or below a specified threshold.

One advantage is the automatic generation of alerts when some monitored parameters fall outside a specified range of values. This solution informs the operator about adjustments to stay ahead or allows the generated indicators to be interpreted as a risk that can be integrated into the design of the production structure.

In one embodiment, retrieving data from the first storage device includes:

reading the tracking code on the surface of the first pipe by activating the optical sensor of the radio antenna;

generating a request to the first server to retrieve at least a subclass of the first data set from the first storage device;

receiving the first set of data on the user's device via a wireless interface.

In one embodiment, a first server manages a plurality of storage devices in a cloud architecture, wherein a second set of data is stored in at least a first storage device of the plurality of storage devices. In one embodiment, the first server periodically transmits the first set of data to the central server.

In one embodiment, the method includes:

reading the tracking code on said first pipe using an optical sensor or radio antenna;

modifying data from the first geometric data subclass or from the second subclass of first pipe joint data using a user interface;

recording the modified data associated with the timestamp into the first storage device;

transmitting the modified data associated with the timestamp to a storage device controlled by a central server, said modified data being associated with a first pipe in said storage device;

updating the digital descriptor of the first pipe.

In one embodiment, the method includes the preliminary step of pairing the first set of data with a tracking code.

In one embodiment, the tracking code on the first pipe is identification marks or markings placed on the surface of the first pipe.

In another aspect, the invention relates to a method for monitoring the condition of a well, wherein a first pipe is configured to be connected to a production structure present in said well, wherein a first server manages a digital descriptor of the first pipe, wherein said digital descriptor comprises a first set of data stored in at least the first a storage device, wherein said first data set comprises at least:

one tracking code for the first pipe; And

inner diameter,

this method also includes:

authenticating the first pipe by capturing the tracking code of the first pipe;

generating a first request for the first server from a computer located next to the first pipe;

obtaining a value for the internal diameter of said first pipe;

automatically calculating the estimated value of drilling fluid increment taking into account the internal diameter of said first pipe and the value resulting from the production structure present in the well;

comparing the calculated estimate of the amount of mud growth with the expected value of the mud increase recorded in the first data set;

generates an alert when the specified comparison is above or below a specified threshold.

The advantage is the implementation of a unique solution that provides either pipe inspection or well control. The parameters of the pipes introduced into the well can be used to calculate some parameters in the well. The resulting structural or mechanical properties of the well, such as the properties of the drilling fluid or cement resulting from the insertion of the pipe, can be used to predict the effects on the remaining pipes that must be inserted.

In another aspect, the invention relates to a method for monitoring the condition of a well, wherein a first pipe is configured to be connected to a production structure present in said well, wherein a first server manages a digital descriptor of the first pipe, wherein said digital descriptor includes a first set of data recorded in at least the first a storage device, wherein said first set of data comprises at least:

one tracking code for the first pipe; And

outside diameter,

this method also includes:

authenticating the first pipe by capturing the tracking code of the first pipe;

generating a first request for the first server from a computer located next to the first pipe;

obtaining a value for the outer diameter of said first pipe;

automatically calculating an estimated volume of cement using at least an outer diameter of said first pipe;

comparing the estimated cement volume estimate with the expected cement value recorded in the first data set;

generates an alert when the specified comparison is above or below a specified threshold.

One benefit is to create an accurate index for the cement that should be injected to service the mining structure. The invention makes it possible to calculate the value for cement in real time before each insertion of the pipe.

In another aspect, the invention relates to a computer program containing instructions that, when the program is executed by a computer, cause the computer to execute a method according to the invention.

In another aspect, the invention relates to a system for managing digital descriptors of a plurality of pipes, each pipe being configured to be connected to a production structure, said system comprising:

a central server addressing a storage device in which the digital descriptor of the first pipe is associated with a tracking code;

at least one local server;

wherein each pipe contains at least one tracking code on the surface of said pipe by activating an optical sensor of the radio antenna;

at least one optical sensor or one radio antenna, called a first sensor, located at each site, wherein said first sensor is configured to capture a tracking code;

wherein the local computer receives the tracking code and generates a request to the local server, said first local computer also comprising means for:

obtaining a first set of data containing values associated with the pipe features;

editing at least one pipe attribute value;

generating an associated timestamp;

transmitting the new value with a corresponding timestamp to the first server;

wherein the communication interface allows the first set of data managed by the central server to be updated, said updated data being written to at least one storage device that archives the previous data with the new data associated with a timestamp added.

In one embodiment, the system according to the invention is configured to implement the method according to the invention.

In another aspect, the invention relates to a pipe comprising at least six markings on its surface, each mark representing the same tracking code, the first set of markings being arranged with cylindrical symmetry such that they are spaced substantially apart by an angle of 120 ° from each other in the first distal portion of the pipe, the second set of markings being arranged with cylindrical symmetry so that they are spaced substantially 120° apart from each other in the second distal portion of the pipe.

DESCRIPTION

Definitions

As used herein, the term “component” means any element or accessory used to drill or operate a well. The component may, for example, be a relatively long pipe element (approximately ten meters in length), for example a pipe or pipe coupling several tens of centimeters long, or an auxiliary device for these pipe elements (hanger, adapter, safety valve, tool spacer , translator, etc.). The component may be a pipeline containing a single long length of tubular element assembled using a coupling.

The component may comprise a single connection or connector or threaded end and is designed to be threaded to another component to form a threaded tubular connection to that other component.

Components of the invention, such as pipes, are designed to be assembled into a final assembly in a well, this final assembly being referred to herein as a "production structure" and designated ST ₁ . These components are typically connected to each other for lowering into a hydrocarbon well or similar wells. The production structure ST1 contains all the components that are to be inserted into the well, such as a drill string, casing or liner, or a string of tubing, such as work strings. For example, a typical well may contain three casing strings with different diameters and lengths, and a liner casing string.

The terms "component", "tubular component" and "pipe" are used interchangeably herein to refer to an ST ₁ production structure element in the sense that the components will always be tubular elements or substantially tubular elements or nearly tubular elements.

The term "work order", designated Jb, refers to the task relating to the preparation of the assembly: the ST ₁ production structure. Also the work order refers to its insertion into the well at the drilling site. The introduction of the mining structure ST ₁ is carried out component T _k+1 by component T _k in accordance with the specified sequence SEQ ₁ . Defining a work order Jb1 involves defining a reference called a “work order link.” All components that are related to the same production structure ST ₁ introduced into well W ₁ are referenced in work order Jb1 using a summary list.

The work order is associated with the following list of items.

Contract number (CN). The contract number refers to the location where the well is being built. The CN contract number can refer to a location, geographic location, or any information that identifies the site where the well is being constructed.

A drilling rig reference that refers to a specific drilling rig deployed at the selected location where the well will be drilled. The drilling rig can be a type of drilling rig on water or on land. Each type of drilling rig may have specific characteristics.

Regarding the final list, the final list is a list of components and associated features that will be introduced into the well.

Different actions to perform with each component.

Work order status: preparation, execution, completion.

The resulting list, designated TAL, refers to all types of equipment that are to be inserted into the W ₁ well, such as drilling equipment, casing equipment, tubing equipment, etc. Each equipment listed in the final TAL ₁ list is associated with other elements that may be indicated in the final list:

a set of features indicating some properties of the specified component T _k ;

a set of features indicating some properties of a list of components interacting with others, such as connection, contact, relative position;

tracking code;

work order status: preparation, execution, completion;

working length;

inner diameter;

The sequence number indicates the order in which each component must be introduced into the well. Moreover, the sequence number provides information about the relationship between the component and the other components within which it is to be connected.

The final list also contains some indicators, such as:

the total length of the set of components T ₁ that are part of the mining structure ST ₁ ;

mud gain (MG), expressed in cubic meters, this indicator can, for example, be extracted from another document or from the results of calculations on a computer, the indicator can be displayed and combined in a summary list, thus it can be considered that it is part of the final list;

the internal volume of the column (string inner volume, SIV), expressed in cubic meters, this indicator can also be extracted from another document or from the result of calculations on a computer, the indicator can be displayed and combined in a summary list, thus it can be considered that it is part of the final list.

The final list can have different states, for example, “preliminary final list” or “current final list”. One advantage is the creation of a custom list of T _k components depending on the location or action that needs to be performed on the component.

For example, an operator at a drilling site such as site 40 must become aware of all components that are located inside and outside of well W1. One advantage is to calculate, for example, the total length of the mining structure at any time. Another advantage is the accuracy of the calculated total length. This allows equipment to be accurately positioned along the structure, especially equipment that may be attached to a specific pipe.

In another example, an operator located at site 30 would like to have a list of components for specific work order Jb1 in order to pay close attention to recent repairs. In this case, the operator does not need access to components that have already been introduced into the well. For this purpose, the operator, through the user interface, will request a preliminary summary list to verify certain actions.

Depending on the preliminary final inventory, the level of accuracy of the data describing the pipes may be documented in a local database.

According to an embodiment of the invention, the computer interface generates a list of components T _k of the production structure ST ₁ of a given well W ₁ . This work task Jb ₁ allows you to present a list of components T _k that are to be introduced into well W ₁ in a given order in a given sequence SEQ ₁ . The specified sequence SEQ ₁ assures the operator that every action he will perform on the component T _k will be performed in the correct order. The SEQ ₁ sequence is created using a control tool accessible from the operator's computer. The sequence SEQ ₁ is written to work order Jb ₁ .

The sequence SEQ ₁ allows the generation of an indicator related to the attachment of components to the production structure ST ₁ before or during their introduction into the well W ₁ .

Thus, the sequence SEQ ₁ is a powerful tool that allows the operator to plan the next actions with the components T _k at each stage.

The invention makes it possible to offer an interface showing:

all components that are to be introduced into this well W ₁ ; And

Automatically generated measurements and metrics to guide actions taken on specified components during drilling and completion operations.

This interface may provide access to all or part of the information in the TAL ₁ summary list and associated work order Jb ₁ , and therefore, for example, the drilling equipment or casing and tubing equipment to be used in the well that is documented in final list.

The advantage of the SEQ1 sequence is to reduce the number of errors made during the installation planning analysis of the ST ₁ production structure. Moreover, it allows you to generate indicators with different levels of accuracy depending on the desired goal to be achieved. Consequently, activity reports are simplified and can be generated automatically.

A "Local Server" SERV _1i is a server assigned to site "i" or area where pipe components can be stored and where data related to pipe features can be recorded. At this point, the local database DB _1i is connected to the local SERV _1i server. This local database DB _1i may be a server storage device or another storage device.

Therefore, in the description of the present invention, "local server" or "local database" can be considered to refer to the same network element having storage and access capabilities, such as Ethernet, RJ45, optical fiber, etc. communication interface.

In fig. 1 shows the technological route of the pipe T ₁ according to the invention, starting from the production section 10 to the section 40, for example, the well W ₁ , and the pipe T ₁ is introduced into the well W ₁ .

In fig. 1 shows the production area 10, the pipe equipment area 20, the inventory and repair area 30 and the destination area 40. The invention is not limited to this site configuration. In various embodiments of the invention, a given pipe may travel from different locations before arriving at its destination.

In fig. Figure 2 shows an example of a process route for a given pipe T ₁ , called the first pipe T ₁ . At time t _0, the first pipe T ₁ is at site A for its manufacture. At time t _1, pipe T ₁ is transported to the second section 20 for the purpose of installing terminal devices at its ends. Pipe T ₁ , for example made from a grade of stainless steel, may also be suitable for a particular surface treatment at station 20. Pipe T ₁ is then moved, for example by vessel 23, at time t ₂ to station 30 to complete inventory step 21. Additionally, at this stage, pipe T ₁ can be assigned to a specific well W ₁ . At this point 30, checks and controls can be completed by the operator. In the example shown in FIG. 2, pipe T ₁ is returned at time t ₃ to station 20. At this point, pipe T1 is adapted or repaired to meet a specific need, for example, specified in a work order data table related to a particular well W ₁ . After repair or adaptation, pipe T ₁ is sent at time t ₄ to section 30, and then delivered at time t ₅ , for example, by vessel 3, to section 40. Section 40, if, for example, well W ₁ .

In another process route, the second pipe T ₂ may be delivered directly from section 10 to section 40. All combinations of routes may be provided in various embodiments of the invention.

Each site 10, 20, 30, 40 or other areas not described where pipe T ₁ may be transported contains a local storage device M ₁ containing a first set of data SET ₁ . The data describing said pipe T ₁ is intended to grow and can be completed throughout the transportation and activities performed on said pipe T ₁ .

In a preferred embodiment, the local storage devices are hosted on a server. In one example, each site 10, 20, 30, 40 contains a local server SERV ₁₁ , SERV ₁₂ , SERV ₁₃ , SERV ₁₄ . In one embodiment, each server may be accessible via a wireless interface such as WIFI. A terminal, such as a mobile device or computer, containing a control interface may communicate with the server. In some embodiments, an authentication server (not shown) may be dedicated to secure communications between the terminal and the local server.

According to one embodiment of the invention, each local server automatically or manually transmits the first set of data to the central server SERV ₀ . According to one embodiment, the first set of data may be recorded in a wearable storage device, which is then synchronized with the central server SERV ₀ . This scenario can occur when the local SERV ₁₄ server is located on a rig, such as offshore, without any wireless connection directly established to the access point. In this configuration, the operator can transmit the first set of data locally and then write the data to the central SERV ₀ server from another site. According to an embodiment, when possible, the local server periodically transmits the first set of data to the central server or central servers.

The transmitted data is associated with a timestamp. The central server SERV0 writes the second set of data SET1 through processing that allows the data to be associated with a specific timestamp if necessary.

The production mill 10 can produce a variety of pipes T _k with different outer and inner diameters and different wall thicknesses, and sometimes with some variations in shape. A set of mechanical characteristics of each pipe can be entered into the first local server S ₁₁ . In fig. Figure 2 shows an example of what information can be stored on the server during the production of pipe T ₁ . For example, effective length (EL), weight (WE), outside diameter (OD), internal diameter (ID), and wall thickness may be determined at section 10 during or after pipe manufacturing T ₁ . At this point, other geometric data may be recorded according to various embodiments of the invention.

According to an embodiment of the invention, the first data set contains workflow SET ₁₃ data used for traceability and logistics purposes. In one embodiment, the pipe T ₁ includes a serial number (SN) and a manufacturing date (MD), which are installed on the first local server SERV ₁₁ during or after the production of the pipe T ₁ . In other embodiments, other information may be recorded on the local SERV ₁₁ at this point.

In one embodiment, the multiple attributes of each manufactured tubular component T _k are primarily achieved through quality control and through non-destructive testing operations on the production mill.

The connections are not necessarily made immediately after the pipe T ₁ is manufactured, but they are made subsequently at the finishing equipment near the mill or at a distance from the mill at station 20. The invention allows both configurations to be considered: when the connections are made at the production mill 10 or at another station 20 .

In most cases, the pipe T ₁ according to the invention is specialized in connecting a production section, such as section 10, with another section, for example section 20. The pipe T ₁ is adapted, equipped or processed later with the appropriate characteristics depending on the customer's requirements and the order. A second subclass of data SET ₁₂ containing connection data may be recorded at section 20 later after pipe T ₁ has been manufactured. In the example shown in FIG. 2, the connection type (CT (1)) and total joint length (JLT) of the specified pipe T ₁ with a specific connection are entered on the local server SERV ₁₂ of site 20.

At station 20, other workflow data may be recorded on the SERV ₁₂ , such as a tracking code (TC) and a contract number CN. In one embodiment, each worker process's data is recorded on local server 12 with an associated timestamp t ₁ .

The input data at SERV ₁₂ is then synchronized with the central server SERV ₀ to write all information to a central storage device or central database (DB) ₀ . In one embodiment, each workflow data item that is transmitted to the central server SERV ₀ is associated with an associated timestamp t ₁ such that each record recorded on the central server SERV ₀ contains each timestamp.

In one embodiment, if there is a conflict between workflow data that is already recorded on the central server SERV ₀ and the same workflow data with a new value that is transferred from the local server SERV ₁₂ to the central server SERV ₀ for recording, the invention allows control conflict by recording the same workflow data with two different values, associating each workflow data metric with its timestamp: t ₀ , t ₁ .

After production, a number of pipe components are sent to a warehouse. In one embodiment, pipe T ₁ arrives at station 20 to be stored, receive a TC tracking code, and optionally receive fits, modifications, or any finishing touches, such as threading on its ends, or a specific connector, or coating treatment. In other examples, each Tk pipe may receive certain adjustments, modifications, or any adjustments at other stages of its transportation.

One consequence is that some data from the second subclass SET ₁₂ from the first data set SET ₁ may be written to the local SERV ₁₂ server.

In the example shown in FIG. 2, pipe T ₁ is modified to be prepared by obtaining a connector INT ₁ at each end. The operator accesses the local SERV ₁₂ server through an interface to determine or update the TC connection type of these connectors INT ₁ and the total length of the joint JLT pipe T ₁ with the specified connectors. This operation is designated SET ₁₂ (CT (INT ₁ ), JLT)

Following the process route, pipe T ₁ is transported to station 30. At station 30, the operator assigns a work order reference and sequence number S ₃ in the sequence SEQ ₁ of the specified work order. In this example, after testing, the statement indicates that modifications must be made to the INT ₁ connectors. Indications such as INT _M are recorded in a local database. Pipe T ₁ is sent to section 20 for repair or modification.

All data from the second and third subclasses SET ₁₂ and SET ₁₃ recorded on the local server SERV ₁₂ is automatically transferred to the central server SERV ₀ , for example, from a backup storage device, operations on which are scheduled every night at a given hour.

In this operation, all data is written to the central server SERV ₀ with their timestamp t ₂ .

In one embodiment, the tubular products T _k may be sent to a location called rig preparation area 30 shown in FIG. 1, wherein the tubular components T _k are prepared in anticipation of their future use during a job on a site or rig, such as section 40. The tubular components T _k may remain in the drilled and completed well, or they may be sent back to rig preparation and stored for future work assignments or, if necessary, sent to a repair shop such as Area 20.

In the example shown in FIG. 2, pipe T ₁ is returned to station 20 to replace connectors INT ₁ , for example, to rethread each connector INT ₁ located at each end of pipe T ₁ . In this example, this operation results in a reduction in the overall length of the JLT joint. After completing the operation, the operator sets a new entry in the local database, that is, on the local server SERV ₁₂ , generating the command SET ₁₂ (CT(INT ₂ ), JLT ₂ ). In this example, the designation INT ₂ refers to the modified connector containing extension threads, and JLT2 refers to the new overall length of pipe T ₁ , taking into account their connectors.

Proper pipe repair may be warranted for a variety of reasons. For example, a repair shop, which may not be controlled by the original manufacturer or end user of a tubular component, may measure the length of a tubular component according to an international API standard that requires length measurements to be accurate to plus or minus 30 mm, whereas the end user may require an accuracy of plus or minus 3 mm .

Therefore, the tubular components may be prepared during site or rig preparation at step 30 or 40.

At each stage, the tubular component can be subjected to appropriate inspection steps. Traits can be updated after monitoring steps during rig preparation. Also, tubular components can be repaired in repair shops or at any manufacturing or repair facility, thereby changing some of the initial characteristics measured on the production mill, as depicted in the example shown in FIG. 2.

In the example shown in FIG. 2, pipe T1 is sent to section 30 at time t4, and then to the well section, section 40 at time t5. At time t ₅ on the drilling rig, the operator can modify a new feature, such as the working length EL of the pipe T1, by measuring in an accurate manner. In this example, the operator enters a new measured working length on the local SERV ₁₄ server. This operation can be implemented to determine with great accuracy the increment of drilling fluid in the well W ₁ .

At this point, the geometric data SET ₁₁ , such as the working length EL, can be updated on the local server SERV ₁₄ . The data recorded on the SERV ₁₄ is then automatically or manually transferred to the central SERV ₀ for synchronization.

The invention provides a method and system in which updated tubular product features _Tk at a local location are written to the corresponding local database of the local server SERV ₁₁ , SERV ₁₂ , SERV ₁₃ , SERV ₁₄ . The local database contains local records regarding the pipe components T _k . The local record contains data representing a pipe element associated with a timestamp, such as t ₁ , t ₂ , t ₃ , t ₄ , in the example shown in FIG. 2. The local SERV _1i server can send local records to the central SERV ₀ database. In various embodiments, the local database may be sent in real time or periodically.

In one embodiment, the local database SERV _1i may be synchronized such that the local database receives central records from the central database SERV ₀ .

The local server's local database may be a mill database, a drilling rig database, or a repair shop database. In this last example, the local database may be a field service database. Field service refers to a repair shop and parts store that has the capabilities to connect machines. Indeed, the tubular components T _k may need to be repaired after transportation or use, or the accessory may be made from a different component.

When measurements are made on a pipe component T _k or modifications are made to a pipe component T _k that change one or more features of the pipe components, then one or more local records representing one or more features are written to the local SERV _1i database via the local user interface .

Synchronization of the local database, i.e. local server SERV _1i , with the central database, i.e. local server SERV ₀ , can be done in real time when the communication interface allows the central server to be accessible to the local server.

In one embodiment, during synchronization for a local database item DB _1i, local records of the local database DB _1i are compared with central records of the central databases DB ₀ . If there is no equivalent local record in the local databases, the local record is retrieved from the local database DB _1i to the central database DB ₀ . In fig. 2 in section 10 at time t0 the working length EL is first set in the local database DB _1i . When this information is synchronized with the central database, a new record is written to the central database DB ₀ .

In one embodiment, the invention also provides facilities such as a local database DB _1i containing data representing central records of the central database DB ₀ . In one example, this local database DB _1i may be configured to contain only a portion of the elements of the central database DB ₀ .

According to one embodiment, the remote database DB _1i is synchronized with the central database DB ₀ in real time or periodically. The predominately remote database DB _1i contains data related to the pipe component T _k at its most recent known update. For example, an operator at site 40 at time t ₅ who is monitoring the connection type CT of pipe T ₁ using the user interface will only see the connection type CT(INT ₂ ).

The central database DB ₀ contains:

characteristics specified by the mill 10 or the repair shop 20, which manufactured or adapted the pipe component T ₁ , and;

updated data from a repair shop or service company that modified or monitored and measured features of the T ₁ pipe component, or from another remote/local DB _1i database.

The remote database DB ₁₄ may correspond to the database of the drilling rig, i.e., the area 40 where measurements are made to verify the characteristics of the tubular component. These measurements are then recorded in the remote database DB ₁₄ as a remote record containing data representing the tubular element measured at the remote location 40 associated with timestamp t ₄ .

The remote database DB ₁₄ can send remote records to the central database DB ₀ .

A drilling rig, such as site 40, most likely does not have a stable data link because the drilling rig may be at sea or in the desert, or it may not always be possible to receive communications through the rig operator's network. The remote database can be synchronized periodically, for example, after a work order has completed.

The central database DB ₀ contains data representing central records from the central database in a first state, such as the state determined at time t ₀ . Thus, the central database DB ₀ may also contain data representing remote records or the local database as central records in a different state, for example, records associated with a different timestamp t ₃ .

During drilling and completion operations in Section 30 or 40, casing and tubing are expected to be run into the wellbore as planned in the sequence specified in the work order data sheet. This SEQ ₁ sequence provides a well integrity assurance and completion program.

A list of components required for casing and completion of well W ₁ is compiled in the work order data table. This work order data sheet provides a summary list that can be used to prepare the rig for operation.

According to the invention, the final list contains a preliminary list (pre-list, P-LIST) ₁ , which contains the sequence SEQ ₁ of which components and when should be introduced into the well W ₁ in a given order. The differences between the preliminary P-LIST ₁ and the work order list (LIST) ₁ are the set of tubular components that are already introduced into the well W ₁ .

The level of detail in the final list depends on the complexity of the well W ₁ . During the run, this list is updated with the actual pipelines lowered into the well. The preliminary list P-LIST ₁ becomes LIST ₁ . This LIST ₁ is also called a run-in-hole (RIH) and is used to verify compliance with the plan and to report activity.

The invention allows you to control the dynamically ordered sequence in the final list to reduce errors that are made during the final stages of introducing components into the drilling rig (RIG). The invention makes it possible to reduce changes or returns of components that are to be introduced into the well, which do not correspond to the final list.

According to one embodiment, the invention takes advantage of marking the pipe T _k with a tracking code TC ₁ to synchronize changes in control and transport of tubular components from their manufacture to their introduction into the well W ₁ .

In one embodiment, the tracking code TC _k of a component T _k is associated with an identifier of said component T _k .

According to one embodiment, each pipe T _k that is to be inserted into the well is marked with a code physically applied to the surface of said pipes. In one example, the marking is an optically readable marking, such as a bar code, for example a type 128 bar code, or a data matrix. In various embodiments, the marking is accomplished by painting, printing, or sticking a label onto the surface of the pipe T _k . According to another example, the marking is performed by laser marking.

According to another embodiment, the marking on the pipe T _k can be carried out by means of a radio tag, such as an RFID tag. The tracking code TC can be written on a passive or active RFID tag, for example, glued to the surface of a pipe T _k .

At each stage of pipe transport _Tk, the operator can read the tracking code TC using an optical sensor or, as it is more commonly called, a reading device such as a camera or radio antenna, such as an RFID reader.

In one embodiment, the reader is placed on a mobile terminal, such as a mobile device, smartphone, tablet, or any laptop computer that is mobile.

In another embodiment, the reader is placed in a predetermined position, for example, for good orientation when the tube T _k moves or moves in front of the camera.

In fig. Figure 3 shows the first pipe T ₁ with markings on its surface. In this diagram, the first pipe T ₁ is almost inserted into the well W ₁ . When the pipe T ₁ stands vertically above the well W ₁ and is in position, the camera 10 receives the bar code TC ₁ . In this configuration, the camera can be placed at a distance of 3 to 5 meters, taking into account the resolution and optical characteristics of the lens.

In one embodiment, camera 10 may be used in conjunction with infrared radiation (IR) or light of a selected wavelength. One benefit is to specify a solution that is compatible with the type of marking.

In one configuration, camera 10 is oriented downward to allow reading while the tube T _k is being rotated.

In one embodiment, compatible presence centralizers, a motion detector, or any algorithm that enhances the decoding of the tracking code may be used with the camera.

The TC bar code ₁ is then decoded by computer 2, which is connected to camera 10. It is assumed that the camera contains a communication interface for transmitting the image to the local computer. Operator 3 can access the decoded bar code through the software system program and interface 4. The tracking code TC can be used to define a corresponding request to the local database DB ₁₄ , for example through the local SERV ₁₄ server.

The TC tracking code is used to recover all information related to the specified Tk pipe. Some geometric information, workflow data, or connection data can be obtained in real time.

The advantage is to generate some indicators or measurements of the entire production structure ST ₁ by using the information of the current component T ₁ that is being analyzed.

Pipe marking

Preferably, the marking is placed on the end of the tubular component. In one embodiment, a marking is placed on each end of the pipe. In one embodiment, a plurality of markings are provided at each end of the pipe. For example, two different markings are separated by 0.2 m along the pipe axis _Tk , as shown in FIG. 3. In one example, the markings are also separated at different angles, 120° in FIG. 3. In one embodiment, the length of the marking is 0.3 meters.

Inventory Status

The first indicator that can be monitored by obtaining from the reader is the pipe ID T ₁ . This first indicator allows you to check the inventory status S ₀ of the component T _k . The identifier may be a tracking code TC or a unique identifier identifying the specified pipe T ₁ . For example, this could be the SN serial number.

Receiving the tracking code TC thanks to the reader allows us to conclude that pipe T ₁ was previously paired, for example at step 10 or 20.

This control allows the generation of a safe indicator S ₀ by controlling each component that is manipulated in the drilling rig 40. This can ensure that a previous component T _n that has been removed from the local database DB ₁₄ , for example, because it could not be used (too much element corruption), not reusable due to incorrect human redirection.

Moreover, the first indicator S ₀ may enable the operation of inserting the pipe T ₁ into the well to be monitored, checking that the marking is not done by default, for example, due to a dirty surface of the component T ₁ that does not allow the marking to be fully visible.

Completion status

In another embodiment, the second indicator can be monitored by obtaining it from a reader. The second indicator refers to the completion state S ₁ . In one embodiment, the termination state S ₁ is an indicator set in the summary list. The second indicator may ensure that the pipe is complete, which means, according to another embodiment, that the following action(s) have been performed:

all necessary modifications have been made on the T ₁ pipe and/or;

pipe T ₁ is equipped with all necessary connecting elements and/or;

a set of necessary checks and measurements has been previously performed in previous stages by at least one operator.

In one embodiment, the termination state S ₁ is analyzed relative to the value(s) of at least one feature of at least one subclass of the first data set SET ₁ .

In one example, the presence of connection type CT and working length EL are monitored. If their values are within the specified scale, the termination state S ₁ passes the test positively.

In another example, the total length with connectors is a unique parameter monitored to check the completion status.

In the example shown in FIG. 3, the second operator 3' monitors the pipe T _k by visual inspection. Some results based on visual inspection, measurement inspection, electrical inspection or any other inspections can be recorded in the local DB ₁₄ database. The results are recorded by passing a new characteristic value or compliance information. The invention allows all information recorded in the database DB ₁₄ to be recorded with a time stamp, for example t ₄ . In one example, the second operator 3' measures the working length of the pipe T ₁ that will be inserted into the well W ₁ . The measured value of the working length of the pipe by operator 3' is then recorded in the database DB ₁₄ . The computer allows you to create records with time stamps in the local database DB ₁₄ .

Planning Status

In another embodiment, the third indicator S ₂ is monitored by decoding the tracking code TC. The third indicator S ₂ represents the planning state. The planning state assures the operator that the component is associated with a work order reference.

The planning state can be defined as a specific attribute in the fourth data subclass. The value of this particular quantity is then compared to the work order reference in the work order data table. The work order data table can be described by the second data set SET2. In one embodiment, this second set of data may be recorded in a second local database DB ₂₄ , for example, at site 40.

According to an embodiment, the comparison results form a planning state.

Sequence state

In another embodiment of the invention, the fourth indicator S ₃ is monitored by decoding the tracking code TC. The third indicator S ₃ represents the state of the sequence. Sequence state S3 assures the operator that the introduction of component T ₁ into well W ₁ is performed in the correct order. If the component number T ₁ in the sequence SEQ ₁ defined in work order Jb1 is 13, this means that the previous component that was inserted into the well has a previous number in the sequence SEQ ₁ equal to 12.

One advantage is the reduction of human errors, especially errors due to improper handling of the pipes before they are inserted into the W ₁ well. Sometimes it is necessary to insert a connecting element or insert a metal mesh element between two successive pipes of the main structure.

The invention makes it possible to reduce the number of errors associated with incorrect handling of a component not planned in the sequence SEQ ₁ .

Control of the third indicator S ₃ can be carried out automatically by recording the number of the last component T _k that was transferred to well W ₁ . In one example, a comparison of two consecutive numbers in a sequence may generate a scheduling status that can be easily verified by an operator through a computer interface.

Length condition

According to another embodiment, the fourth indicator is generated by decoding the TC tracking code.

Obtaining the length of the pipe T ₁ can be used to calculate the total current length of the production structure ST ₁ , which includes the first pipe T ₁ . The length obtained may refer to the total length or the working length of the pipe T ₁ .

The method according to the invention makes it possible to automatically retrieve the total length of the inserted pipe T ₁ and the current total length of the production structure ST ₁ already located inside the well. In one embodiment, the current total length of the production structure ST ₁ is recorded in the computer storage device 2 or in the local database storage device DB ₁₄ . According to one embodiment, the current total length of the mining structure ST ₁ is updated with each new entry.

The length condition of the entire structure allows the theoretical value to be provided, which is calculated in the work order data table. Values can be compared to form a length state.

Drilling Fluid Condition

According to another embodiment, the fifth indicator is generated by decoding the TC tracking code.

Obtaining the internal diameter ID ₁ of pipe T ₁ together with the outer diameter OD ₁ or wall thickness WT ₁ can be used to calculate the increment of drilling fluid that may occur in the well after the introduction of said pipe T ₁ .

The production may concern the inner diameter ID ₁ or the outer diameter OD ₁ taking into account the value of the wall thickness WT ₁ .

The method according to the invention makes it possible to automatically extract the drilling fluid increment value from the ID ₁ value of the internal diameter of the pipe T ₁ and the drilling mud increment value previously calculated for the current structure, which is already located inside the well W ₁ . The invention makes it possible to carry out component-by-component measurement of the amount of drilling fluid increment, taking into account the current component intended for insertion into the well W1, and the rest of the structure located inside the well.

In one embodiment, the current increment of drilling fluid is recorded each time it is injected into the well W ₁ in the computer storage device 2 or in the local database storage device DB ₁₄ . According to one embodiment, the current increment of drilling fluid of the production structure ST ₁ is updated with each new record.

The mud state can be generated by comparing the update value calculated each time a new pipe T ₁ is reintroduced into the well W ₁ and the expected mud increase value, which can be obtained from the work order data table. This value is a theoretical value that can be calculated according to the well properties.

This allows a loss of apparent mud volume in the well to be detected and a warning of a possible fracture in the well, or it can detect an increase in the apparent volume of mud in the well.

Condition of the external volume of the structure

According to another embodiment, the sixth indicator is generated by decoding the TC tracking code.

Obtaining the outer diameter OD1 and working length EL of the pipe _T1 can be used to calculate the external volume of the structure to be inserted into the well.

The external volume of the structure corresponds to the volume occupied by the mining structure, without taking into account the internal free space when calculating the volume.

The production may concern the outer diameter OD1 or the inner diameter ID ₁ taking into account the value of the wall thickness WT ₁ .

The method according to the invention makes it possible to automatically extract the volume of the production structure lowered into the well W ₁ from the value of the outer diameter OD ₁ or from the wall thickness (WT) ₁ and the internal diameter ID ₁ , as well as the working length EL pipe T ₁ and the value of the external volume of the structure, previously calculated from the current structure, which is already inside the well W ₁ . In one embodiment, the current volume of the structure is recorded in the computer storage device 2 or in the local database storage device DB ₁₄ . In one embodiment, the structure volume value is updated with each new entry.

Condition of the cement

According to another embodiment, the seventh indicator is generated by decoding the TC tracking code.

Similar to the outer volume of the structure, obtaining the outer diameter OD1 of pipe T ₁ can be used to calculate the volume of cement that can be injected into the well to strengthen the structure ST ₁ , which is being constructed piecemeal.

The production may concern the outer diameter OD1 or the inner diameter ID ₁ taking into account the value of the wall thickness WT ₁ .

The method according to the invention makes it possible to automatically extract the volume of cement for injection into the well W ₁ from the outer diameter OD ₁ of the pipe T ₁ and the volume of cement previously calculated for the current structure, which is already located inside the well W ₁ . The invention makes it possible to measure component by component the volume of cement that must be introduced into the well, taking into account the current component intended for insertion into the well W ₁ .

In one embodiment, the current volume of cement is recorded in the storage device of the computer 2 or in the storage device of the local database DB₁₄. According to one embodiment, the value cement volume is updated with each new entry.

The cement condition can be generated by comparing the renewal amount calculated each time a new pipe T ₁ is reintroduced into the well W ₁ and the expected cement volume value, which can be obtained from the work order data table. This value is a theoretical value that can be calculated according to the well properties. This method allows you to more accurately determine the volume of cement required to strengthen the well structure.

In one embodiment, the volume of cement is extracted from well data determined by the well operator and from the external volume of the recovery structure.

In fig. 4 shows an embodiment of the method according to the invention, comprising three steps.

The first step involves defining and transmitting REQ ₁ from the user's computer, such as a mobile device or workstation, to the local database DB _1i . At this stage, the method obtains the identification number of the pipe T ₁ . The ID number can be obtained through the camera or can be entered manually through the interface.

After request REQ1 is generated, the local server transmits at least the first set of data SET ₁ . In an embodiment, the local server transmits a second data set SET ₂ containing at least a work order data table. This latter configuration may appear at section 30 or 40, for example.

The method includes a data receiving/receiving step allowing generation of at least one indicator, such as those previously defined. The method is designated as ACQ. Various data can be obtained according to various embodiments of the invention. The receiving step can be automatically generated, for example, after reading the tracking code. The receipt may appear as a display area on your computer showing some of the data received. The receive may indicate preference data that is associated with the user request REQ ₁ .

The third step of the method involves generating an alert, especially when the metric value resulting from an operation on the received data is greater than, less than, equal to, or different from the expected value from a specified range of values.

In fig. 5 shows an embodiment of the invention in which a preliminary step of reading a tracking code is performed. This step can be performed at each stage, i.e. at each site where the local database DB _1i is present. This stage is called READ_CODE.

In fig. 6 shows an embodiment in which the update step of the central database DB ₀ is performed. This stage is called UPD. Updating the data in the central database DB ₀ allows each local database BD1I to be updated with the current characteristics of each pipe T _k .

In one example, modifications to pipe T ₁ in section 20 may be recorded in the local database DB ₁₂ and the update can then be completed in the central database DB ₀ . When pipe T ₁ arrives at site 30, the modified features of pipe T ₁ can be restored in the local database DB ₁₃ due to its synchronization with the central database DB ₀ .

One of the advantages of this stage is the proposal of a method that maintains up to date the values of attributes, modifications, adaptations, reports and checks of each component at each site. This reduces errors, controls the integration of wells of the ST ₁ production structure and reduces the time to create such a structure.
