Stand Break Detection in Drill Rig Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During logging-while-tripping operations, it is challenging to accurately convert measurements taken as a function of time into measurements as a function of position within the wellbore, particularly due to complexities in identifying stand breaks and correlating sensor data from drill rigs to specific events like drill pipe removals.
Innovation Solution
A system and method that utilize sensors to receive and process movement data from various components of a drill rig, identifying stand breaks and determining the length of drill pipes removed by comparing sensor data from multiple sources, and using a drill pipe identification table to facilitate the conversion of time-based measurements into position-based data.

Engineering Contradiction Analysis
1Measurement precision
If manual identification of stand breaks is used during logging-while-tripping operations, then operational flexibility is maintained, but measurement accuracy and conversion reliability deteriorate due to human error and inconsistency
Solution Approach 1:
The patent replaces manual identification of stand breaks with an automated computer-based system that processes sensor data. The system automatically detects stand breaks by analyzing movement data from sensors, eliminating human error and inconsistency while maintaining operational flexibility through programmable algorithms.
Solution Approach 2:
The system enables self-service by automatically converting time-based measurements to position-based measurements without requiring manual intervention. The computer system independently performs stand break detection, data correlation, and conversion operations, reducing reliance on human operators while improving measurement accuracy.
2Reliability
If automated stand break detection is implemented, then measurement conversion accuracy improves, but device complexity and initial operational cost increase
Solution Approach 1:
The patent implements a multi-functional system where a single computer system performs multiple operations: detecting stand breaks, correlating sensor data from multiple sources, converting time-based measurements to position-based measurements, and generating reports. This universal approach improves conversion reliability while managing system complexity through integrated functionality.
Solution Approach 2:
The system introduces a computer-based intermediary that mediates between raw sensor data and final measurements. This intermediary processes and correlates data from multiple sensors, automatically identifies stand breaks, and performs the conversion from time to position measurements, ensuring reliable and consistent results.
3Measurement precision
If multiple sensors are deployed for stand break detection, then detection accuracy improves, but cost and system complexity increase
Solution Approach 1:
The patent combines data from multiple sensors into a unified analysis process. The computer system integrates sensor data to detect stand breaks, correlating information from different sensor sources to improve detection accuracy while managing the quantity of sensors through efficient data fusion and processing.
