Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling systems lack a reliable and efficient method to measure toolface angle consistency and calculate slide stability during slide drilling operations, leading to inefficiencies and increased costs due to uncertainties in drilling orientation and curvature creation.
Innovation Solution
The implementation of a system that measures toolface angles and calculates a slide stability score, expressed as a percentage, using sensors and a controller to assess the consistency of toolface angles and adjust drilling parameters for improved directional control and reduced sliding length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slide drilling operations are performed to create directional bores and curves in the wellbore, then the ability to reach underground hydrocarbon deposits is improved, but the cost and time of the drilling operation increase due to reduced productivity and extended sliding length
Solution Approach 1:
The system continuously measures toolface angles during slide drilling operations and provides real-time feedback through a slide stability score. This feedback loop enables operators to monitor toolface consistency and adjust drilling parameters dynamically, optimizing the balance between directional control capability and drilling productivity.
2Ease of operation
If operators manually monitor and adjust toolface orientation during slide drilling, then directional control is achieved, but measurement precision and reliability are insufficient due to lack of consistent toolface angle measurement
Solution Approach 1:
The patent replaces manual visual monitoring and estimation of toolface orientation with an automated electronic measurement system using magnetic sensors and gyroscopes. This substitution provides precise, objective measurement of toolface angles and enables automated calculation of slide stability, significantly improving measurement precision while maintaining operational ease.
3Adaptability or versatility
If slide drilling is used instead of rotary drilling to create curves in the wellbore, then the ability to navigate complex well paths is improved, but equipment wear increases and drilling time is extended
Solution Approach 1:
The system calculates and displays a slide stability score before and during slide drilling operations, providing advance information about expected toolface consistency. This preliminary assessment allows operators to plan slide drilling operations more effectively, select appropriate slide lengths, and anticipate potential issues, thereby optimizing well path navigation while minimizing unnecessary sliding and equipment wear.

AI summary
Systems, devices, and methods for measuring toolface angles on a drilling rig and calculating a slide stability score are provided. The slide stability score may represent an amount of consistency of the toolface angle of a bottom hole assembly (BHA) of the drilling rig during a slide drilling operation. Calculating the slide stability score may include measuring one or more toolface angles of the BHA during the slide drilling operation, comparing the measured one or more toolface angles, and calculating the consistency of the toolface angle using the measured one or more toolface angles.
