Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling processes face challenges in accurately determining the geologic 'Geostop' marker, leading to well control issues and significant financial losses due to the inability to set drill casing close enough to depleted zones or significant geologic pressure transition zones.
Innovation Solution
A wellbore tool equipped with a petro-physical property identification device, featuring a casing with equally spaced pads and pockets housing batteries and sensors, allows for real-time confirmation of the geologic 'Geostop' marker, enabling precise placement of drill casing and facilitating easy removal of components post-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional drilling processes are used to determine geologic stop points, then drilling operations can proceed with standard equipment, but the accuracy of identifying the geologic 'Geostop' marker is limited leading to well control issues and financial losses
Solution Approach 1:
The patent applies preliminary action by placing a petro-physical identification device in the wellbore before drilling reaches the target depth. This device contains sensors that detect formation properties ahead of time, allowing operators to identify the geologic stop point in advance and set casing at the correct location, thereby improving both measurement precision and well control reliability
Solution Approach 2:
The patent replaces conventional mechanical drilling processes with a sensor-based detection system. Instead of relying on traditional drilling mechanics and post-drilling analysis, the invention uses electronic sensors to detect formation properties and identify the geologic stop point, significantly improving measurement accuracy and enabling real-time decision-making for well control
2Reliability
If drill casing is set further from the depleted zone to ensure safety, then well control issues are reduced, but the ability to place casing close to the target zone is compromised leading to increased drilling costs
Solution Approach 1:
The patent implements feedback by using sensors to continuously monitor formation properties and provide real-time data about the approaching geologic stop point. This feedback loop allows operators to adjust drilling parameters and casing placement decisions dynamically, ensuring both safety and efficiency by placing casing as close as possible to the target zone with confidence
3Device complexity
If cutting sample identification at the surface is used to define geologic stop points, then equipment complexity is minimized, but the success rate of determining accurate stop points is limited
Solution Approach 1:
The patent introduces an intermediary device - the petro-physical identification device with sensors - that acts as a mediator between the drilling operation and the geologic formation. This intermediary provides direct measurement capability downhole, eliminating the need for indirect surface-based cutting sample analysis and dramatically improving determination accuracy while maintaining operational simplicity
