Definitions
- Drilling techniques may vary depending on the type of formation, the location of the rig, the product to be extracted, etc.
- a well-bore plan, or other previously designed plan for drilling the borehole is implemented via a computing system or human operations, in conjunction with the borehole assembly, to ensure accurate drilling measurements. Accurate drilling measurements ensure that the reservoir of product, such as oil and/or gas, is reached during the drilling process.
- the borehole assembly may include a directional tool, such as a Measurement While Drilling (MWD) tool, often having internal computers that use accelerometers and magnetometers to determine the direction of the tool heading, otherwise referred to as the high-side of the tool.
- MWD Measurement While Drilling
- a downhole tool such as a drilling motor, mud motor, or any other suitable downhole tool, may also be utilized.
- the downhole tool may include a bent housing located at a bottom end of the tool, such as the bottom end of the drilling motor.
- the downhole tool While the downhole tool does not have computer technology within itself, it may be attached to the directional tool during drilling operations.
- the directional tool may operate according to the well-bore plan, thereby controlling the direction of the downhole tool according to the well-bore plan.
- the heading of the directional tool and the heading of the downhole tool may be different.
- the heading of the various drilling tools may be indicated by a high-side marking, or other indicator, that is marked on the exterior of the drilling tool.
- the offset between the directional tool heading and the downhole tool heading referred to as the angular offset or scribe line offset (SLO)
- SLO angular offset or scribe line offset
- Conventional techniques for calculating the SLO are often left to human approximations.
- conventional techniques include a rig employee using line of sight to roughly estimate the SLO.
- An employee may stand at the base of the downhole tool, beneath a directional tool suspended above, and estimate the SLO between a high-side marking indicating the heading of the directional tool and a high-side marking indicating the heading of the downhole tool.
- This method of calculating the SLO leaves room for significant human error as little accuracy can be ensured using human estimations alone.
- a drilling employee may be standing at a distance of seventy feet, or longer, below the high-side marking of the directional tool, making it very difficult to visually estimate the offset between the heading of the directional tool and the heading of the downhole tool. Mistakes in the directional-drilling measurements can lead to problems drilling the wellbore, and even abandonment, resulting in costly and time-consuming setbacks.
- the drilling environment can be filled with many hazardous conditions related to drilling machinery and operations. For example, requiring that an employee stand below a suspended MWD during drilling operations can lead to increased risk of human injury.

- the sensing component may be securely attached adjacent to the high- side marking of a drilling tool, which indicates the heading of the tool, and may be located opposite the target component. Exact placement of the sensing component may vary depending on the weight restrictions and drilling requirements of the rig. For example, the sensing component may be securely attached adjacent to the high-side marking of a downhole tool in some examples or may be securely attached adjacent to the high- side marking of a drilling tool in other examples. In additional examples, the sensing component may be placed adjacent to a top-drive located above both the drilling tool and the directional tool.

- FIG. 1 illustrates an example drilling rig environment 100 implementing an angular offset apparatus 102 according to some examples.
- the angular offset apparatus 102 includes a sensing component 104, a target component 106, and a computing device 108.
- the sensing component 104 is placed adjacent to the high- side marking of a downhole tool 116.

The combined image rendered, or the individual images, may then be used to determine the location of the high-side marking of the directional tool 114.
- the computing device 108 can determine the angular offset between the location of the two high-side markings of the directional tool 114 and the downhole tool 116, otherwise referred to as the scribe line offset (SLO).
- SLO scribe line offset
- the use of imaging data and computerized calculations helps significantly improve the accuracy of the SLO value, as opposed to conventional techniques that utilize line of sight alone.

- the rendered images may be stored in cloud-based storage, servers, or other storage applications.
- the placement of the sensing component 104 and the target component 106 may vary according to the rig environment, design considerations, etc.
- the target component 106 could be mounted onto a tool located above the directional tool 114, such as a top- drive. In this example, the target component may still be aligned with a high-side marking of the directional tool 114 while mounted above the top-drive.

- an angular offset apparatus may implement a local positioning system.
- the local positioning system may implement one or more beacons or antennas, or other apparatuses capable of collecting and transmitting local positioning data.
- Each antenna may be located at the high-side of a drilling tool, such as the directional tool 114 and the downhole tool 116 illustrated in FIG. 1.
- a grid system is determined and components of the local positioning system may be placed adjacent to known locations. For example, four local positioning components, may be placed adjacent to four corners of the drilling environment 100, with each of the four components placed adjacent to a known location. In other examples, any number and configuration of local positioning components may be implemented according to the unique drilling environment.
- each beacon or antenna may ping off the known locations and collect data, including the time period needed for the ping to travel to the local positioning component from each beacon or antenna, the time period needed for the ping to return to each beacon or antenna from the local positioning component, and information regarding where each beacon or antenna is located, such as the at the high-side marking of a drilling tool to which the antenna or beacon is attached.
- the collected data may then be provided to the computing device 108 and, utilizing the collected data, the angular offset, or SLO, is determined by the computing device 108.
- the SLO may then be accounted for in the well-bore plan and ultimately provided to the directional tool 114 via the computing device 108 to be accounted for during drilling operations.

- the imaging sensors 204, 206 may be placed away from the high-side marking of the downhole tool 202. In this embodiment, the offset between the sensors 204, 206 is determined and accounted for when calculating the SLO.

- the sensing component may be lifted manually by the one or more transport mechanisms 212, 214, or via machinery utilizing the transport mechanisms 212, 214, depending on the drilling rig, weight of the sensing component 200, difficulty of placement, and safety considerations.
- the transport mechanisms 212, 214 may also be configured to allow for rotation of components of the mounting mechanism, such as the mounting brackets 216, 218, 220, 222.
- the connecting brackets 224, 226 may be located at a first end and a second end of the transport mechanisms 212, 214.

Abstract
Cette invention concerne un appareil de décalage angulaire destiné à déterminer un décalage angulaire, ou un décalage de ligne de repère (SLO), de deux objets au sein d'un environnement de forage. L'appareil de décalage angulaire peut comprendre un composant de détection et un composant de marquage situés à divers emplacements au sein de l'environnement de forage. Le composant de détection peut mettre en œuvre un ou plusieurs capteurs configurés pour collecter des données associées au composant de marquage et à l'environnement de forage pour déterminer le décalage de ligne de repère entre les deux objets. L'appareil de décalage angulaire, conjointement avec le décalage de ligne de repère calculé, est conçu pour garantir la précision et la sécurité pendant les opérations de forage.
