Downhole Test Apparatus for Well Device Function Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current well systems lack downhole mechanisms to perform tests verifying the successful completion of functions by downhole well tools and devices, and to communicate these test results to the surface.
Innovation Solution
Incorporating a downhole test apparatus within the well system that can perform tests to determine if downhole functions, such as setting or actuating packer elements or anchoring, have been successfully completed, and communicate the results to the surface using various indication types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If downhole well tools and devices perform various functions, then operational capability is improved, but inability to verify function completion and communicate results reduces reliability
Solution Approach 1:
The patent implements feedback mechanisms where test apparatus downhole communicates test results back to the surface. This allows verification of whether downhole functions were performed successfully, providing continuous feedback on system operation and enabling real-time decision-making about well operations.
Solution Approach 2:
The patent introduces intermediary communication mechanisms between the downhole test apparatus and surface equipment. These intermediaries transmit test results and function status information from the downhole environment to the surface, enabling information flow without requiring direct human presence downhole.
2Reliability
If downhole test apparatus is added to verify function completion, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines test apparatus functionality with existing downhole well tools and devices. By integrating test capabilities into the well tools themselves rather than adding separate systems, the patent reduces overall complexity while maintaining verification capabilities.
Solution Approach 2:
The patent designs downhole well tools with multi-functionality, enabling them to both perform well operations and conduct self-testing. This universal approach allows a single device to serve multiple purposes, reducing the need for additional specialized equipment.
3Productivity
If real-time communication of test results is implemented, then operational efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic communication of test results rather than continuous transmission. Test data is communicated at intervals or upon completion of specific test sequences, reducing energy consumption while maintaining operational efficiency by providing timely information without constant energy expenditure.

AI summary
Systems, methods, and apparatus for performing a downhole test of completion of a function performed by a downhole well device in a well system and communicating the test results to the surface. A downhole well device may perform a downhole function in the well system. For example, the downhole function may be a setting function, an actuating function, or an anchoring function. A downhole test apparatus may perform a downhole test to determine whether the downhole function was completed successfully. For example, the downhole test may be a downhole seal test or a downhole anchor test. Based on the result of the downhole test, the downhole test apparatus may provide an indication from downhole to surface equipment of the well system that indicates whether the downhole function was completed successfully.
