Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional resistivity data analysis methods are used, then the analysis process is simple, but the reliability of downhole location determination and formation localization is insufficient
Solution Approach 1:
The patent transforms conventional 2D resistivity data representation into multiple 3D view perspectives (e.g., top-down, side, cross-sectional views) of the borehole environment. This dimensional transformation allows operators to visualize subterranean formations and borehole location from multiple angles simultaneously, significantly improving the reliability of location determination while managing system complexity through software-based rendering.
Solution Approach 2:
The patent segments the complex resistivity data into multiple independent view perspectives, each showing a specific orientation or aspect of the borehole environment. By dividing the data representation into manageable segments (different views), the system makes complex data more interpretable without overwhelming the analysis capacity, thereby improving reliability while keeping the analysis process structured and controllable.
2Measurement precision
If multiple view perspectives are generated, then the accuracy of formation analysis is improved, but the data processing complexity increases
Solution Approach 1:
The patent creates a universal data processing framework that generates multiple view perspectives from a single set of resistivity measurements. This multi-functional system can produce various orientations (top-down, side, cross-sectional views) simultaneously from the same input data, improving measurement precision without requiring separate processing systems for each view, thus managing complexity through a unified approach.
Solution Approach 2:
The patent creates multiple copies of the resistivity data representation, each transformed into a different view perspective. Rather than processing fundamentally different data sets, the system generates replicated views (copies) of the same underlying data from different angular perspectives, which improves analysis accuracy while maintaining efficient data processing through reuse of the original measurements.
3Ease of operation
If multiple synchronized view perspectives are provided, then the geo-steering decision-making is improved, but the computational resources required increase
Solution Approach 1:
The patent performs preliminary processing of resistivity data to create a comprehensive multi-perspective view framework before actual geo-steering decisions are made. By pre-generating and synchronizing multiple view perspectives in advance, the system reduces real-time computational requirements during critical decision-making moments, improving ease of operation while managing energy consumption through upfront data preparation.
Data Source
AI summary
The disclosure presents processes that utilize collected resistivity data, for example, from an ultra-deep resistivity tool located downhole a borehole. In some aspects, each slice of resistivity data can generate multiple distribution curves that can be overlaid offset resistivity logs. In some aspects, an analysis can be performed to identify trends in the distribution curves that can be used to identify approximate locations of subterranean formation surfaces, shoulder beds, obstacles, proximate boreholes, and other borehole and geological characteristics. As the number of distribution curves generated increase, the confidence in the analysis also increases. In some aspects, the number of distribution curves can be twenty, one hundred, one hundred and one, or other counts of distribution curves. In some aspects, the resistivity data can be used to generate two or more synchronized view perspectives of a specific location along the borehole, where each view perspective uses the same focus area.
