Engineering Contradiction Analysis
1Manufacturing precision
If multi-Z polylines are used to accurately represent salt body boundaries, then modeling accuracy is improved, but processing time and computational power requirements increase significantly
Solution Approach 1:
The patent segments the complex multi-Z polyline data into multiple single-Z polyline segments. Each segment represents a portion of the salt body boundary with a single Z value, allowing independent processing. This segmentation maintains the overall accuracy of the salt body model while enabling parallel processing and reducing the computational complexity of rendering operations.
2Manufacturing precision
If multi-Z polylines are used to capture complex salt body geometries, then representation accuracy is improved, but device complexity and processing requirements worsen
Solution Approach 1:
The patent divides the complex multi-Z polyline into multiple simpler single-Z polyline segments. Each segment has reduced complexity with a single Z value, making them easier to process and store. The segmentation approach maintains geometric accuracy by preserving the boundary definition while simplifying the data structure for more efficient handling by imaging systems.
3Manufacturing precision
If multi-Z polylines are used to define salt body contours, then boundary accuracy is improved, but rendering efficiency deteriorates
Solution Approach 1:
The patent segments the multi-Z polyline boundary definition into multiple single-Z polyline segments. This segmentation enables more efficient rendering by allowing the imaging system to process each segment independently and in parallel, significantly improving rendering efficiency while maintaining the accuracy of the salt body boundary representation.

AI summary
Method and system for 3-D imaging of subterranean geologic structures based on seismic data interpretations involves converting multi-Z polylines into single-Z line segments. The single-Z line segments have slopes that are either positive or negative and do not change signs. As a result, no point along the line segment has more than one value in Z. The single-Z line segments may then be grouped or assembled into lattices that may then be used to form single-z horizons. Such a method and system arrangement provide a far more efficient and less processing intensive way to render 3-D images of the geologic structures compared to existing solutions.
