Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual specification of horizons and slices is used to view attribute renderings, then the analysis precision is improved, but the time consumption increases
Solution Approach 1:
The system performs preliminary automatic horizon identification and slice calculation based on user input parameters, preparing the analysis framework in advance before the user views the attribute renderings. This eliminates the need for manual horizon specification during the analysis process, maintaining precision while reducing time consumption.
Solution Approach 2:
The system enables self-service automatic horizon detection and slice generation that operates independently once parameters are set. The computer automatically identifies horizons, calculates stratal slices, and generates attribute renderings without requiring continuous manual intervention, thus preserving analysis precision while dramatically reducing time consumption.
2Loss of information
If sequences of attribute renderings are displayed one after another, then the completeness of geological feature analysis is improved, but the productivity decreases
Solution Approach 1:
The system transitions from sequential 2D slice display to a 3D interactive visualization where multiple slices and horizons are simultaneously visible. Users can navigate through the volume interactively, examining geological features across multiple dimensions at once, which maintains analytical completeness while significantly improving productivity by eliminating sequential viewing.
3Measurement precision
If manual calculation of stratal slices is performed, then the accuracy of horizon-based analysis is improved, but the device complexity increases
Solution Approach 1:
The system replaces manual mechanical calculation processes with automated computer-based algorithms. The computer automatically performs horizon detection, stratal slice calculation, and attribute rendering generation based on user input parameters, maintaining high accuracy while reducing system complexity by eliminating manual intervention requirements.

AI summary
The computer system and computer-implemented method allow a user to position an interactive cursor my interaction with a user-input device, to select a point anywhere within a 3D seismic data volume that is visible on a display. In response, the computer dynamically calculates a horizon-based stratal slice that includes the user-selected point. A selected attribute rendering from seismic data that is contained within the horizon-based stratal slice is automatically calculated and dynamically shown on a second display.
