Well Log Visualization Using Cell-Based Depth Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional well log visualization methods, such as long paper charts, lose spatial context as borehole depth increases and are cumbersome for comparing multiple wells simultaneously, making it difficult to analyze and evaluate geological formations effectively.
Innovation Solution
A cell-based visualization system that presents well log data as a pattern of blocks and subcells on a GUI, where each cell and subcell corresponds to a specific depth unit, with graphic effects like color, pattern, or brightness representing parameter values, allowing for a compact and intuitive view of geological formations and enabling side-by-side comparison of multiple wells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional paper charts are used to visualize well log data, then detailed information of geological formations can be provided, but the charts become excessively long as borehole depth increases, leading to loss of spatial context and difficulty in evaluation
Solution Approach 1:
The patent transforms the traditional linear one-dimensional paper chart into a two-dimensional graphical interface where the vertical axis represents depth and the horizontal axis represents multiple wells or parameters simultaneously. This dimensional transformation allows multiple wells to be compared side-by-side on a single screen, preventing loss of spatial context while avoiding excessive length issues.
Solution Approach 2:
The patent divides the continuous well log data into discrete depth intervals or segments, each represented as a separate visual element in the graphical interface. This segmentation allows the data to be organized into manageable units that can be displayed compactly while maintaining the ability to drill down into specific depth ranges for detailed analysis.
2Adaptability or versatility
If paper charts are used for well log visualization, then geological formation information can be displayed, but comparing multiple wells concurrently becomes cumbersome
Solution Approach 1:
The graphical interface is designed to handle multiple wells simultaneously within a single unified display framework. The system can display multiple well logs side-by-side, allowing users to compare geological formations, parameters, and depth intervals across different wells without needing separate charts for each well, thereby enabling efficient multi-well analysis.
3Loss of information
If detailed well log data is presented in conventional format, then comprehensive geological information is available, but the data becomes difficult to evaluate and analyze
Solution Approach 1:
The patent applies color coding and graphical effects to represent different geological formations, parameter ranges, and data characteristics. By mapping data values to visual properties such as color intensity, shading, or pattern, the system enhances the interpretability of complex well log data, allowing users to quickly identify formations, anomalies, and trends without being overwhelmed by numerical complexity.

AI summary
In some examples, a system may receive log data including a depth-series of data for a sensed parameter. The system may determine a parameter value of the depth series data for individual subunits of depth corresponding to a larger unit of depth. The system may further determine a scale of graphic effects corresponding to parameter values for the depth-series data. The system may present, on a display, a visualization of the depth-series data. For instance, the visualization may include a plurality of cells arranged in a plurality of rows, with each cell corresponding to the larger unit of depth and including a plurality of subcells corresponding to the subunits of depth. Additionally, each subcell may be presented with a respective graphic effect corresponding to the parameter value determined at a corresponding depth, and the graphic effect may correspond to the parameter value on the scale of graphic effects.
