Wellbore Inversion Model Confidence Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wellbore operations, inversion models of wellbore characteristics can be misinterpreted due to uncertainty in data collection, leading to inaccurate steering and inefficient operations, particularly beyond the depth of detection limit where confidence values decrease.
Innovation Solution
A visual indicator is used to overlay confidence values onto the inversion model, adjusting opacity, hue, saturation, or brightness based on confidence levels, allowing for better differentiation between accurate and inaccurate data representation and aiding in adjusting wellbore operations.

Engineering Contradiction Analysis
1Volume of moving object
If inversion modeling is performed beyond the depth of detection limit, then more extensive wellbore coverage is achieved, but data reliability and accuracy deteriorate due to decreasing confidence values
Solution Approach 1:
The patent applies local quality by varying the visual properties (opacity, color saturation, brightness) of different regions in the inversion model based on their confidence values. Regions with high confidence are displayed with full opacity and normal color intensity, while regions with low confidence are displayed with reduced opacity and muted colors, allowing operators to visually distinguish reliable from unreliable data within the same model.
Solution Approach 2:
The patent utilizes color changes as a visual indicator to represent confidence levels in the inversion model. Different color intensities, saturations, or hues are applied to different regions based on their confidence values, enabling operators to quickly identify areas with low confidence that may require cautious interpretation or additional verification.
2Measurement precision
If visual indicators are added to display confidence values, then data interpretation accuracy is improved, but display complexity increases
Solution Approach 1:
The patent merges the confidence value information with the existing inversion model display by overlaying visual indicators directly on top of the model data. This integration allows confidence information to be conveyed without requiring separate displays or additional physical devices, maintaining a unified visual interface that presents both structural and confidence information simultaneously.
Solution Approach 2:
The patent uses color changes, opacity adjustments, and brightness modifications as visual indicators to represent confidence values. These visual properties are modified based on confidence levels, providing an intuitive and immediate way for operators to assess data reliability without adding complex numerical displays or requiring additional interpretation steps.
Data Source
AI summary
A system can display confidence values in a wellbore inversion model using a visual indicator. The system can receive downhole data relating to the wellbore from a downhole tool deployed in a wellbore of a geological formation during a wellbore operation. The system can additionally generate an inversion model of the geological formation by performing inversion processing on the downhole data. Furthermore, the system can determine confidence values for the downhole data in the inversion model. Additionally, the system can determine a depth of detection limit for the downhole data based on the confidence values. The system can output the inversion model, the depth of detection limit, and a visual indicator based on the confidence values for display at a display device for use in adjusting the wellbore operation.
