SIMPLE FULL WELL HEAD

[001] The present Utility Model patent application relates to a Single Integral Well Head and other components such as Extended Type Single Column Suspenders and the Special Biflanged Adapter with Rotating and Concentric Fianges, all exclusive to the Head. Simple Integral Wells, which complement the present utility model patent application and are surface mounted and more precisely connected to the Production Facing or installed over the Facing Head of oil producing or fluid injection wells.

[002] The present Utility Model patent application refers to the Simple Integral Well Head with the concept of Horizontal Simple Christmas Tree and other specific components such as; Single Column Crosshead Type Extended Column Suspension with characteristics suitable for applications in emerging wells, pumped wells, water injection wells, steam injection wells and gas injection wells; Special Concentric Biflagellate Adapter with Rotating Top and Bottom Fianges. These are surface mounted equipment over the Casing Head or directly connected to the Oil Producing Well or Fluid Injection Casing, as well as anchor the Pipe Column which is the conductor for the production or injection of fluid into wells. oil or injection wells.

They are components intended to direct the flow of produced fluids or injected fluids into the well, having the particularities of offering the installation and anchoring of a Pipe Column for oil production or fluid injection; offer a technically viable and operationally safe system for the installation and anchoring of a Pipe Column, which in the technical language of petroleum engineering is called simple completion; enable and optimize production rig interventions in oil production recovery or maintenance operations normally occurring during the productive life of oil wells or fluid injection wells.

[004] The present utility model patent application has as its main object the improvements in patent application PI0803219-0 A2, called “SIMPLE INTEGRAL WELL HEAD”, TO COMPLETE FACILITIES IN oil-producing WELLS operating by natural and artificial lifting; wells operating by alternate and rotary mechanical pumping methods; oil wells pumped by the submerged electric pumping system; emerging oil wells; cyclic and continuous steam injection wells; gas injection wells and injection and water wells, all with subsurface installations with a Pipe and Component Column, called simple completion.

GROUNDS OF IMPROVEMENTS

[005] The present Utility Model patent application has fundamentally the concept of Simple Horizontal Christmas Tree and various objectives and various technical and operational advantages over the installations of the state of the art components and to replace with technical and operational advantages the components. basic in use and standardized, among which we can cite: - Production Head, state of the art component, considering the various models; Single Column Suspension; Flanged adapter; Simple Christmas Tree (Valve Set) conventional flanged type or conventional threaded type, all prior art components; equip and complete the facilities of the Oil Well Heads, whose subsurface installations include only one Pipe Column or Production Column, either for production by the alternative mechanical pumping method and other pumping methods; as for facilities for rising wells and continuous or selective water injection wells; gas injection wells; continuous or cyclic steam injection wells; selective steam injection wells; streamline operations, ie enable well intervention with the Drill or Production Probe, without the need to disconnect the Production Line or Emergency Line or the Steam Injection or Water Injection Line, or Gas Injection and consequently there is no need for LAYOUT modifications to the Wellhead installations and surface installations before, during and after interventions with the Drilling Rig or Production Probe.

As already mentioned, the Simple Integral Wellhead will replace the standard and state-of-the-art basic components, Production Heads and Christmas Tree and other components currently used in standard oil well surface compositions in the facilities. called simple completions; to improve the facilities and the technical and operational and especially safety conditions of surface installations.

It should be noted that the Single Integral Wellhead, object of this Utility Model patent application, has the upper section or end flanged connection and the lower section or end two types of connections: flanged or threaded. The model with flanged type lower connection, for installation in medium to high pressure wells, allows installation on the Coating Head, which has flanged type connection in the upper section; which is a basic and specific component of a state of the art constructed or drilled well.

[008] The model with threaded type bottom fitting allows connection to the surface finish or production finish, which is a patronized and specific component of a constructed or drilled well, referring to the installation of wells with low or medium pressure characteristic, which is usually a well characteristic that operates by the artificial lifting method and alternative mechanical pump system and also by other pump methods.

We also highlight that the improvements made in the design of the current application, which are the main objective of the present Utility Model patent application and the main object of this report, are also very relevant and will contribute to the technical, operational and safety improvements during installation of specific components as well as ease of installation over other components that make up the Wellhead, surface components of the constructed or perforated well; as Surface or Production Coating and Coating Head; The Utility Model patent application allows the installation of the safety system, called BOP, for Drilling Rig or Production Drill operations, during well production maintenance interventions and operations, and the recovery and replacement of the Drilling Column. Pipes or Production Column, without the need to disconnect the Production Line or Surge, or Fluid Injection Line, maintaining the LAYOUT of the wellhead and surface installations.

[010] It is important to consider that these technical and operational conditions are also very relevant in well surface installations in Offshore Oil Rigs and consequently reduce the time wasted in performing various operational procedures and activities and also reduce oil production losses.

TECHNICAL STATE

[011] Oil production wells with the characteristics of springs (wells that have their own energy); oil producing wells, through the various lifting methods (pumped wells); injection wells and water abstraction; cyclic and continuous steam injection wells; selective steam injection wells and gas producing and injector wells typically feature subsurface installations with a Pipe Column and other specific and referent components, referred to as simple completion; They also feature dual tube installations, called double completion.

[012] Surface installations, for simple completion, object of the present work, present as their main feature, an equipment called Simple Flanged Crosshead or Threaded Crosshead Christmas Tree, with gate or ball type valves and other accessories for the application in wells with medium to high pressure characteristics. It also features Simplified Threaded Flow Tee Christmas Tree and a Stuffing Box Device for low pressure wells and applied to the production well by the alternative mechanical pumping method.

[013] In our work, we are considering only wells equipped for simple completion, which include only one (1) Pipe Column and specific and referent components. These wells, equipped for simple completion, feature as surface components or also known as Wellhead components, the following basic and standardized equipment: Casing Head, Casing Column Suspender, Production Head, Pipe Column Suspender, Flanged Adapter, Stuffing Box, Single Flanged Block Christmas Tree, Single Flanged or Threaded Cross Christmas Tree and Simplified Christmas Tree, all applied to wells, gas injection wells, injection wells. steam, water injection wells, production wells by the lifting method by the electric pumping system and wells using the lifting methods of production by alternative or rotary mechanical pumping.

[014] These state-of-the-art installations have operational deficiencies, particularly with regard to the technical and operational feasibility of interventions with BOP Drilling Rigs and installation and safety equipment, which is standardized and mandatory to install. Wellhead to initiate and perform any operation on the well. For the installation of safety equipment called BOP and to perform well operations with the Drill or Production Probe, it is necessary to disconnect the surface installations or Production Line or Emergency Line and also all equipment installed on the Head. Production is withdrawn and consequently the original LAYOUT of the Wellhead, peripherals and surface installation components are disconnected.

Of course here we are dealing with wells with facilities for simple completion for both rising wells and pumped wells. In wells pumped by reciprocating mechanical pumping systems, the Pumping Units (UB) are stopped and the wells are closed, later the Production Lines or Emergency Lines are disconnected and all components installed on the Production Head are disconnected. In wells pumped by rotary mechanical pumping systems, the Heads (Mechanical Electrical Device) are shut down and the wells are closed, then the Production Lines or Emergency Lines are disconnected and all components installed on the Production Heads are disconnected.

[016] We may consider that the wells undergo early oil production shutdowns due to the procedures applied and require the early removal of surface components, which are installed on the Production Head. According to the above reports, the components to be removed vary depending on the characteristics of the well installed components and the production or injection methods as well as the applied pumping methods. Importantly, one of the main surface components in an oil well, the Christmas Tree, which in our work is currently called Simple Christmas Tree, may be for emerging wells or pumped wells, is the first set to be inoperative, as well as the Production or Injection Lines, all in preparation for the entry of the Drilling Rig or Production Probe.

[017] Only after the removal of all these components can we install safety equipment called BOP, without which the drilling or production rigs do not work in oil producing wells. Another relevant aspect, regarding the loss of oil production, occurs after the completion of the services performed by the Production Rigs, is the time that is lost for the well to return to normal operation until the restoration and restoration works are performed. surface recovery, ie recovering or rebuilding the Wellhead LAYOUT and surface installations, along with all required components as well as testing of all installations.

[018] The procedures described are operational techniques with very representative and time consuming difficulty levels; resulting in the loss of oil production before and after the production rig intervention; increasing uptime or downtime and costs. As mentioned above, these are procedures that are required for the assembly of the Production Probe and the installation of the BOP, safety equipment required and mandatory for interventions and operations to be performed in the well; As well as disconnecting components from the Wellhead, more precisely those installed on the Production Head, the Disconnection of the Production Line or Emergency Line, which directs the fluids produced by the well for storage in the Collection Stations, is also processed.

[019] During Production Probe interventions, it is generally necessary to move up the Tube Column or Production Column, which is anchored by the Single Column Suspension, and as the outside diameter of this Column Suspension is larger than the diameter. components installed on the Production Head, hence the need to disconnect all components installed on the Production Head. These are procedures performed in the State of the Art, so that the safety equipment, BOP and the scheduled interventions and operations can be safely installed, as well as the upward movement of the Pipe Column, which is inside the well.

[059] Improvement of simple and conceptual technical and operational technology of Horizontal Simple Christmas Tree, which includes surface installations in oil producing wells with subsurface installation with a Pipe Column and Other Components, called simple completion. For application to existing oil producing wells using Alternative Mechanical Pumping (BM) methods; Rotary Mechanical Pump (BCP) method, Submerged Electric Pump (BCS) method, emerging oil wells; injection wells and water abstraction; gas injection wells; steam injection wells and also for new wells with the same characteristics and production or injection methods mentioned above, all with features and facilities for simple completion.

We emphasize that all State of the Art components installed on the Coating Head will be replaced in their entirety by the components of the Single Integral Wellhead, object of this report, totally altering or modifying the LAYOUT in the Wellhead and surface installations, considering Of course, these changes will reduce the height of the Wellhead, simplifying and reducing the peripheral components of the Wellhead; We also highlight the concept and characteristics similar to that of Simple Horizontal Christmas Tree, which has as its main objective the facilities and the optimization of the operational procedures for the entrance with Drilling Rigs or Production Rigs and to perform the interventions in oil wells; which basically represents the installation of safety equipment, called BOP, the basis for any rig activity in an oil well; This operation is facilitated because the Single Integral Wellhead enables, due to its characteristics, that is, only the Flanged Adapter, connected over the Single Integral Wellhead, object of this report, is removed.

[061] We also highlight the operational safety and maintenance or preservation of the Production Line or Emergency Line, or fluid injection line during Production Probe interventions, to maintain production and consequently reduce waste time. reworking of production or emergency lines facilities and reducing the loss of oil production. We highlight as described above, when installing the Single Integral Wellhead, that the Wellhead installations and Production or Injection Lines will become permanent, ie the Wellhead LAYOUT and Surface Installations will not be disconnected for the entrance and assembly of the Production Probe for intervention in the well, a situation different from the occurrences and procedures performed in the State of the Art.

[062] The Single Integral Wellhead, object of this Utility Model patent application, was developed and designed to replace Production Heads and Single Column Suspensions, regardless of their characteristics and application; replace the Simple Christmas Tree, all state of the art components. It is a HYBRID and INNOVATIVE upgrade, as as already described above, it will replace with technical and operational advantages several standard state of the art components such as: Production Head, Single Column Suspenders and Single Christmas Tree, State of the art components. Technical and most importantly, improving the technical and operational and safety conditions. The upgrade will also enable the operational and safety needs of injection wells and water abstraction wells, cyclic and continuous steam injection wells, emerging oil wells (which have their own energy when naturally produced fluid elevation occurs), wells that use lifting method through gas injection and wells that use the Alternative or Rotary Mechanical Pump methods; all of these wells have features and facilities for simple completion, for lifting produced fluids or injected fluids.

[063] The upgrade will suit surface component installations such as: Casing Head and Casing Column Suspension, installed during well construction or drilling; Flanged adapter, with characteristics suitable for installations according to well design and lifting or injection methods; Stuffing Box; Flanged Gate Valves or Threaded Ball Valves; all state of the art components in use and standardized.

[064] The improvement contemplates the prerogatives of the concept of Simple Horizontal Christmas Tree and system of optimized operations, that is, the intervention in the well, with Production Probe, should occur without the need to disconnect the Production Lines or the Injection. other technical and operational as well as safety advantages while maintaining the original LAYOUT of the Wellhead and surface component installations.

[065] For Production Offshore Platform Wellhead installations, the Single Integral Wellhead referenced herein, which is the subject of this report, is a considerable and advantageous solution over current State of the art installations. If we consider the space to be sufficiently small to support the various Wellheads installed and the LAYOUT of the Production or Injection Lines, this is defined according to the wellhead component installation project. This situation and / or current condition is well characterized when the entry of Drilling or Production Rigs for interventions and operations, where it will normally be necessary to disconnect the Production or Injection Lines, as well as to disconnect and remove the Christmas Tree. and Flanged Adapter; These procedures are usually performed in order to install the safety equipment called BOP, without which interventions and operations in oil wells are not performed and as already mentioned, the reduced space in the Offshore Production Platforms (OFF-SHORE) facilities. ), greatly increases the level of technical and operational difficulties and especially safety; increasing the time for the necessary procedures and consequently costs.

[066] This is why we have previously mentioned that the Single Integral Wellhead, referenced here, which is the subject of this report, is a considerable and advantageous solution over current State of the art facilities in the ON-SHORE and OFF- SHORE (maritime), as for interventions with Production or Drilling Rigs to perform well maintenance interventions and operations, these operations are called 'Workover'; technical activities and operating procedures will be optimized; which basically and only represents the installation of safety equipment, called BOP, the basis for any drilling or production rig activity in an oil well; The procedures are optimized and facilitated, as the Simple Integral Wellhead allows, due to its characteristics, that is, only the Flanged Adapter, Flanged Drawer Valve or Threaded Ball Valve in emerging wells, and the component called Packing Box ( Stuffing Box), in pumped wells that are connected over the Device, Single Integral Wellhead, object of this report, will be disconnected and removed.

[067] We also highlight the operational safety and maintenance of surface installations LAYOUT, ie the preservation of the Production Line or Emergency Line, or Fluid Injection Line during Production Probe interventions, to maintain the consequently reduce the waste of rework time at the production or emergency lines facilities and reduce the loss of oil production, while maintaining operational safety, technical safety, environmental safety throughout the well's productive life. environment and the technicians participating in the specific and related interventions.
