Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data quality assurance operations are used, then data validation can be performed with expert knowledge, but the process is time-intensive and reduces productivity
Solution Approach 1:
The patent replaces manual mechanical data validation operations with an automated computer system that uses processors to execute validation algorithms. The system automatically compares deviation survey data against defined tolerances and checks perforation event positions using conditional logic, eliminating the need for manual expert review while maintaining validation quality.
Solution Approach 2:
The validation system performs self-service by automatically executing consistency checks without requiring continuous human intervention. The computer system independently validates well trajectory data and perforation event attributes, generating quality assurance reports automatically and reducing dependency on manual expert operations.
2Reliability
If manual data quality assurance is performed, then expert expertise can be applied to complex data, but inconsistencies in well trajectory and perforation event data may remain
Solution Approach 1:
The system performs preliminary validation actions by automatically checking data consistency before simulation modeling begins. The well trajectory evaluator and perforation event analyzer execute consistency checks in advance, identifying and flagging potential issues before they affect subsequent simulation processes, thereby preventing time-consuming revisions later.
Solution Approach 2:
The validation system implements feedback mechanisms by continuously comparing deviation survey data against defined tolerances and generating quality assurance reports that provide immediate feedback on data consistency. The system identifies inconsistencies in well trajectory and perforation event data and provides detailed reports enabling rapid correction before simulation modeling.
3Productivity
If automated validation systems are implemented, then data processing speed increases, but system complexity increases
Solution Approach 1:
The validation system is segmented into distinct functional modules: a well trajectory evaluator that validates trajectory data consistency, a perforation event analyzer that checks perforation positions, and a quality assurance reporter that generates validation reports. This modular segmentation reduces overall system complexity by making each component independent and easier to develop, maintain, and debug.
