Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for negative pressure testing in the oil and gas industry face challenges in accurately monitoring pressure changes in 'open' or 'closed' systems of choke manifold and blow-out preventer (BOP) components, particularly in identifying pressure deviations outside acceptable bounds in real-time.
Innovation Solution
The implementation of a software-based system, such as the Negative Test Analyst, which utilizes algorithms to calculate pressure changes based on measured pressures and user-configurable parameters, providing real-time feedback through a traffic light system and allowing for the selection of appropriate test parameters like Duration, LargestAcceptableRise, and LargestAcceptableFall, to determine test outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual pressure monitoring methods are used in negative pressure testing, then the system complexity is reduced, but the measurement precision and real-time detection capability deteriorate
Solution Approach 1:
The patent replaces manual mechanical pressure monitoring with an automated software-based system that continuously calculates pressure changes based on measured pressures and user-configurable parameters. The Negative Test Analyst software automatically detects pressure deviations outside acceptable bounds in real-time, eliminating the need for manual monitoring while significantly improving measurement precision and detection accuracy.
Solution Approach 2:
The system implements real-time feedback through a traffic light system that provides immediate visual indication of test status (pass, fail, or inconclusive). The software continuously monitors pressure changes and provides real-time feedback on whether pressure deviations remain within acceptable bounds, enabling operators to respond immediately to test outcomes.
2Speed
If real-time pressure monitoring is implemented, then the detection speed of pressure deviations improves, but the data processing complexity increases
Solution Approach 1:
The Negative Test Analyst software performs self-service by automatically calculating pressure changes, comparing them against user-configurable parameters (Duration, LargestAcceptableRise, LargestAcceptableFall), and determining test outcomes without requiring complex manual data processing. The system autonomously manages the entire pressure monitoring and analysis process, simplifying operations while maintaining high detection speed.
Solution Approach 2:
The system uses user-configurable parameters (Duration, LargestAcceptableRise, LargestAcceptableFall) to define acceptable pressure deviation bounds. By allowing users to set these parameters based on specific test requirements, the system adapts to different testing scenarios without requiring complex custom algorithms for each case, thus maintaining processing simplicity while achieving real-time detection.
3Productivity
If automated software analysis is used, then the productivity and efficiency of negative pressure testing improve, but the initial device complexity and implementation cost increase
Solution Approach 1:
The Negative Test Analyst software is designed as a universal system that handles multiple aspects of negative pressure testing through a single integrated platform. It performs pressure change calculations, compares results against configurable parameters, determines test outcomes, and provides real-time feedback - replacing multiple separate tools or manual processes with one multi-functional software solution that improves overall testing productivity.
