Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling technologies struggle with accurately measuring and maintaining wellbore depth due to manual errors and inadequate integration of downhole sensor data, leading to costly mistakes and reduced well output.
Innovation Solution
A computer-implemented system using processor-executable instructions for integrating reference data from downhole sensors and surface control systems to automate and improve drilling operations, incorporating a steering control system that processes data from MWD and LWD tools to correct well trajectory errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual pipe tallying is performed using measuring tapes and tally books, then the process can be completed with simple equipment, but measurement accuracy deteriorates due to human errors including wrong tally, inaccurate measurements, and mis-communication
Solution Approach 1:
The patent replaces the manual mechanical tallying system (measuring tapes and tally books) with an automated optical/electronic system using cameras, image processing algorithms, and computer vision technology to detect and measure drill pipe joints, eliminating human measurement errors while maintaining equipment simplicity
Solution Approach 2:
The system enables self-service by allowing the drilling operation to automatically record and tally pipe depths through continuous imaging and automated joint detection, without requiring manual intervention from rig crew members for measurement and recording
2Productivity
If manual pipe tallying is performed in a fast-paced dynamic environment, then the process can keep up with drilling speed, but reliability deteriorates due to gross errors and mis-communication between crew members
Solution Approach 1:
The patent implements continuous automated monitoring and recording of pipe tally information throughout the drilling operation, eliminating interruptions and ensuring consistent data capture regardless of the fast-paced dynamic environment, thereby maintaining both productivity and reliability
Solution Approach 2:
The system provides real-time feedback by continuously capturing images, detecting joints, calculating depths, and updating tally records automatically, allowing immediate detection and correction of any discrepancies while maintaining accurate records throughout the drilling process
3Measurement precision
If automated pipe tallying with cameras and image processing is implemented, then measurement precision improves by eliminating manual errors, but device complexity increases due to additional equipment and processing requirements
Solution Approach 1:
The patent integrates multiple functions into a single automated system that simultaneously performs imaging, joint detection, depth calculation, and tally recording, eliminating the need for separate manual operations and reducing overall system complexity despite the advanced capabilities provided
Solution Approach 2:
The patent uses image processing algorithms and computer vision software as intermediaries between the camera system and the tally recording system, automatically translating visual data into measurement information without requiring complex direct integration between hardware components
Data Source
AI summary
Systems for pipe tallying in well drilling operations and methods for using the same are described. The pipe tallying systems determine a number of pipe joints that pass through an inlet based on the diameter of the pipe joint when compared against a drill pipe diameter. The pipe tally system maintains a tally of drill pipes in a borehole and the pipe tally system can produce a borehole depth measurement based on the length of pipe in the borehole.
