Automated Offset Selection for Drilling Performance Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual selection of offset runs for drilling performance evaluation is subjective and varies based on individual training and geographic location, leading to inconsistent comparisons.
Innovation Solution
A method is disclosed for automatically selecting offset runs by determining a score for each potential offset run based on weighted parameters such as geographic distance, depth difference, run date, and drilling system component matching, and then ranking and comparing these runs for performance evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual selection of offset runs is performed, then flexibility in selection criteria can be maintained, but selection consistency and objectivity deteriorate due to individual training variations and geographic location differences
Solution Approach 1:
The patent replaces the manual mechanical selection process with an automated computer-based system that objectively evaluates offset runs based on predefined criteria including geographic location, depth, formation, BHA design, and drilling parameters, eliminating human subjectivity while maintaining selection flexibility through configurable weightings
Solution Approach 2:
The system changes the selection approach by introducing a multi-parameter scoring system where each offset run is evaluated on multiple parameters (geographic distance, depth difference, formation similarity, etc.) with assignable weightings, transforming the selection from a subjective judgment to an objective quantitative comparison
2Measurement precision
If automated offset selection is implemented, then selection objectivity and consistency are improved, but system complexity increases due to multiple parameters and scoring calculations
Solution Approach 1:
The patent segments the offset selection process into distinct evaluative components: geographic criteria, depth criteria, formation criteria, BHA criteria, and drilling parameter criteria, each scored separately and then aggregated, making the complex system manageable and transparent
Solution Approach 2:
The system creates a universal selection framework that can evaluate any drilling run against any offset runs using the same multi-parameter scoring system, making the complex apparatus applicable across different geographic locations, drilling conditions, and evaluation scenarios
3Measurement precision
If multiple parameters with weightings are used for scoring, then selection accuracy is improved, but computational requirements and processing time increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing the parameter weightings and evaluation criteria before the actual offset selection occurs, allowing the scoring calculations to proceed efficiently through standardized computations rather than requiring real-time complex decision-making

AI summary
A method for selecting potential offset drilling runs to automatically evaluate a drilling performance of a subject drilling run includes identifying the potential offset drilling runs based upon the subject drilling run. The potential offset drilling runs are identified based upon a status of a drilling system component that is used to drill the subject drilling run. The method also includes determining a score for each of the potential offset drilling runs, ranking the potential offset drilling runs based upon the score of each of the potential offset drilling runs, and identifying a subset of the potential offset drilling runs based upon the ranking. The method also includes performing a plurality of comparisons of the drilling performance of the subject drilling run against drilling performances of the subset and selecting one of a plurality of drilling system components used in the subset based at least partially upon the first comparisons.
