Well Construction Decision Support for Drilling Plan Deviations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drillers face challenges in making optimal well construction decisions due to the lack of effective decision support tools for leveraging real-time and historical data, leading to inefficiencies and errors in wellbore construction operations.
Innovation Solution
A system that measures drilling operating parameters, calculates well state parameters, and adjusts the well plan when deviations exceed thresholds, providing users with modified tasks to correct inefficiencies or errors, and allowing remote monitoring by well construction engineers to communicate instructions for correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drillers rely on their own skills and experience to make drilling decisions, then they can operate without external support, but decision quality varies and optimal decisions cannot be consistently achieved
Solution Approach 1:
The system continuously monitors drilling parameters and provides real-time feedback to drillers through the decision support interface, enabling consistent optimal decisions by comparing actual performance against predetermined criteria and suggesting corrective actions
Solution Approach 2:
The decision support system acts as an intermediary between raw drilling data and driller decisions, processing information and providing recommended actions that bridge the gap between data collection and optimal decision-making
2Reliability
If well construction engineers remotely monitor wellbores in real-time, then inefficiencies and errors can be identified earlier, but communication delays and coordination complexity increase
Solution Approach 1:
The system pre-establishes criteria for inefficiencies and errors in the well construction plan, enabling automatic detection and early warning before problems manifest physically, allowing preventive action rather than reactive response
Solution Approach 2:
Real-time monitoring data feeds back to both remote engineers and on-site drillers simultaneously, enabling immediate identification and correction of deviations from the well construction plan without communication delays
3Adaptability or versatility
If multiple personnel are involved in well construction operations, then diverse expertise is available, but coordinating decisions and actions becomes complex
Solution Approach 1:
The decision support system serves multiple functions simultaneously: monitoring drilling parameters, comparing against the well construction plan, identifying deviations, and providing recommended actions to various personnel roles (drillers, engineers, service personnel) through a unified interface
Solution Approach 2:
The system merges data from multiple sources (drilling parameters, well construction plan, formation data) and consolidates coordination functions into a single integrated platform that all personnel access, eliminating the need for separate communication channels and reducing coordination complexity

AI summary
A method for wellbore construction management includes measuring at least one drilling operating parameter during drilling of a wellbore. At least one well state parameter is calculated from the measured drilling operating parameter. A difference between the calculated well state parameter and a predetermined value of the well state parameter is determined. When the difference exceeds a selected threshold a modified well plan is calculated comprising at least one drilling task to enable construction of at least part of the wellbore to conform to the modified well plan. The at least one drilling task is displayed to a user.
