Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If single seismic source type is used, then device complexity is reduced, but measurement precision and understanding of geologic formations deteriorates
Solution Approach 1:
The patent segments the seismic source configuration into multiple distinct source types (e.g., vertical, horizontal, radial sources) with different radiation patterns. Each source type targets specific geological features or wave types, allowing comprehensive subsurface imaging through coordinated use of multiple specialized sources rather than a single omnibus source.
Solution Approach 2:
The patent implements a universal seismic survey system that can accommodate multiple source types within a single survey framework. The system design allows any combination of source types to be used together, providing multi-functionality that adapts to different geological conditions and exploration objectives while maintaining a unified data processing and interpretation platform.
2Measurement precision
If multiple seismic source types are used, then measurement precision of geologic formations is improved, but computational time increases
Solution Approach 1:
The patent performs preliminary classification and characterization of different source types and their expected contributions to the survey objectives before the actual survey execution. This preliminary planning optimizes the combination of source types and their deployment parameters, reducing the need for extensive computational iterations during data processing while maintaining high measurement precision.
Solution Approach 2:
The patent applies partial action by selectively using only the necessary subset of source types required for specific survey objectives rather than deploying all possible source types universally. This selective approach reduces computational complexity while maintaining sufficient measurement precision for the targeted geological features.
3Loss of information
If multiple seismic source types are used, then understanding of geologic formations is enhanced, but cost increases
Solution Approach 1:
The patent implements a dynamic survey design where the combination and deployment of different source types can be adjusted based on real-time survey progress, preliminary findings, and specific geological targets. This dynamic adaptability allows optimization of resource allocation, using more sophisticated multiple source types only where and when they provide the most value, thereby reducing overall survey costs while maintaining comprehensive geological information gathering.
