Geological Image Log Format Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying two-dimensional geological image data from different planar slices of a rock sample lack a continuous or semi-continuous presentation format, making it difficult to interpret and understand the context and reservoir orientation of the samples.
Innovation Solution
A method that captures two-dimensional images of geological samples in a sequence, determines if any images need replacement with gaps, joins them to form a continuous stitched image, calculates proportional magnitudes of geological phases, and plots these magnitudes on a graph in a log format, allowing for a more intuitive and context-rich display.

1Loss of information
If two-dimensional geological images from different planar slices are displayed individually or stacked in 3D volume, then the images can be displayed and analyzed for petrophysical parameters, but the presentation lacks continuity and contextual information about reservoir orientation
Solution Approach 1:
The patent combines multiple 2D images from different planar slices into a single continuous log format display. The method projects images from various slices (XY, XZ, YZ planes) onto a common log format coordinate system, merging spatial information from different orientations into one unified presentation that maintains continuity and provides comprehensive contextual information about reservoir orientation.
Solution Approach 2:
The patent transitions from displaying images in their original 2D planar formats or stacked 3D volumes to a new log format that adds a dimensional transformation. The log format uses depth or position along the sample as one axis and incorporates spatial coordinates from multiple planes as additional dimensions, creating a semi-continuous presentation that reveals reservoir orientation information not apparent in traditional displays.
2Measurement precision
If multiple two-dimensional images are captured and processed to maintain reservoir orientation and highlight trends, then analytical capabilities are improved, but the processing complexity and time increase
Solution Approach 1:
The patent performs preliminary processing steps including capturing images from multiple planar slices and organizing them by spatial coordinates before the final log format projection. By pre-processing and organizing the image data with metadata about their spatial positions and orientations, the method reduces the computational burden during the actual log format generation, thereby reducing overall processing time while maintaining analytical accuracy.
