Directional Setting Tool Single-Trip Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for setting and orienting well tools in subterranean wells require multiple trips into the wellbore, making the process inefficient and time-consuming, particularly for achieving accurate orientation of whipstocks and other assemblies.
Innovation Solution
A setting tool equipped with a setting mechanism and an orientation indicator, such as a three-axis accelerometer, is used to set the well tool and provide real-time orientation indications, allowing for the anchor to be set and oriented azimuthally in a single trip, enabling precise engagement of assemblies relative to the wellbore.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional multi-trip methods are used to set and orient well tools, then orientation accuracy can be achieved, but the number of trips and time required increases significantly
Solution Approach 1:
The patent combines the setting function and orientation indication function into a single integrated tool. The setting tool includes both a setting mechanism (such as a setting shoe or setting sleeve) and an orientation indicator (such as a magnetometer or accelerometer), allowing both functions to be performed during one trip into the wellbore, eliminating the need for separate trips to set the tool and then orient it.
Solution Approach 2:
The setting tool is designed with multi-functionality, serving both to set the well tool (such as an anchor or whipstock) and to indicate its orientation simultaneously. This universal tool eliminates the need for specialized separate tools for setting and orientation, reducing the number of trips required while maintaining orientation accuracy.
2Ease of operation
If multiple separate tools are used for setting and orientation, then each function can be performed independently, but the device complexity and number of trips increase
Solution Approach 1:
The patent merges multiple separate tools (setting tool and orientation indicator) into a single integrated setting tool. The setting mechanism and orientation indicator are combined in one tool assembly that can be run into the wellbore as a single unit, reducing the number of tools and trips while maintaining the ability to perform both functions.
Solution Approach 2:
The integrated setting tool performs multiple functions simultaneously - it can set the well tool (such as expanding an anchor or setting a whipstock) while also measuring and indicating orientation using integrated sensors like magnetometers or accelerometers, eliminating the need for multiple specialized tools.
3Ease of manufacture
If traditional setting methods are used without integrated orientation indication, then the setting process is simpler, but additional trips are required to achieve proper orientation
Solution Approach 1:
The patent combines the setting operation with real-time orientation indication in a single integrated tool. The setting mechanism (such as a setting shoe that expands to set an anchor) works simultaneously with orientation sensors (magnetometers or accelerometers) to provide real-time feedback on tool orientation, allowing the operator to achieve proper orientation during the same trip as the setting operation.
Solution Approach 2:
The integrated orientation indicator provides real-time feedback to the operator during the setting operation. This feedback allows the operator to adjust the orientation of the well tool while it is being set, ensuring proper orientation is achieved during the same trip without requiring additional trips for orientation adjustment.

Function Achieved in This Case
This approach significantly reduces the number of trips required, enhances the accuracy of well tool orientation, and streamlines the process of setting and engaging assemblies, improving operational efficiency and reducing the complexity of wellbore operations.

AI summary
A setting tool for setting a well tool in a wellbore includes a setting mechanism which is operative to apply a setting force to set the well tool, and an orientation indicator which indicates an orientation of the setting tool. A method of setting a well tool and engaging an assembly with the well tool includes setting the well tool in a wellbore utilizing a setting tool which includes an orientation indicator, and then engaging the assembly with the well tool, thereby fixing an orientation of the assembly relative to the well tool. A method of azimuthally orienting a whipstock in a wellbore includes setting an anchor in the wellbore, the anchor including an alignment device, and indicating an azimuthal orientation of the alignment device relative to the wellbore. The anchor setting and azimuthal orientation indicating are performed using only a single trip into the wellbore.
