Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Directional drilling projects face challenges in maintaining the actual drilling trajectory aligned with the planned trajectory due to uncertainties in steering response, which are not effectively addressed by existing technologies.
Innovation Solution
A method and system that utilize a computer-implemented approach to receive steering commands, determine actual steering responses, store datasets for uncertainty analysis, and output a visual representation of steering response uncertainty using heat maps and ellipses to guide adjustments in drilling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If steering commands are issued to maintain planned drilling trajectory, then drilling accuracy is improved, but uncertainty in actual steering response increases deviation from planned trajectory
Solution Approach 1:
The system continuously monitors actual steering response and compares it with expected steering response, using this feedback to update uncertainty estimates and adjust drilling parameters in real-time to maintain trajectory accuracy despite steering uncertainties
Solution Approach 2:
The system performs preliminary analysis of steering response characteristics and pre-calculates compensation parameters before executing steering commands, allowing operators to anticipate and compensate for potential steering deviations from the planned trajectory
2Manufacturing precision
If real-time steering adjustments are made to correct trajectory deviations, then drilling precision is improved, but operational complexity increases
Solution Approach 1:
The system automatically generates and executes compensation parameters based on monitored steering responses, allowing the drilling system to self-correct trajectory deviations without requiring complex manual intervention or overly complicated control logic
Solution Approach 2:
The system adjusts drilling parameters such as steering magnitude and rate dynamically based on real-time uncertainty estimates, transforming complex trajectory correction problems into manageable parameter adjustments that maintain precision while simplifying control operations
3Reliability
If uncertainty levels are monitored and accounted for in drilling decisions, then drilling reliability is improved, but decision-making time increases
Solution Approach 1:
The system performs preliminary characterization of steering response uncertainty patterns and pre-establishes compensation strategies, allowing operators to make rapid informed decisions during actual drilling operations without time-consuming real-time analysis
Solution Approach 2:
The system replaces complex manual decision-making processes with automated algorithms that quickly process uncertainty data and generate appropriate drilling adjustments, reducing decision-making time while maintaining or improving reliability through consistent, data-driven decisions

AI summary
A computer-implemented method including receiving a steering command identifying a tool face orientation in which the steering command is expected to produce an intended steering response of an intended drilling trajectory. The method further includes receiving an actual steering response result of the steering command in which the actual steering response result identifies an actual drilling trajectory. The method further includes storing a dataset comparing the actual steering response result in relation to the intended steering response, determining an uncertainty level of the tool face orientation based on the stored dataset, and outputting a visual representation of steering response with the uncertainty level.
