Seismic Data Sampling Probe Resolution Enhancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seismic data imaging techniques face challenges in achieving high resolution, particularly in structurally complex subsurface geometries, due to computational intensity and the need for unmigrated input datasets, which limits interactive interpretation and distorts waveforms.
Innovation Solution
The method involves positioning a sampling probe around seismic data, extracting seismic data perpendicular to a reflection surface closest to the probe's center, and displaying these data in a visible planar face to form an enhanced image, which can be implemented using computer-executable instructions and graphical libraries for real-time visualization.

Engineering Contradiction Analysis
1Measurement precision
If conventional seismic data imaging techniques are used, then computational intensity is reduced, but resolution is poor and waveforms are distorted
Solution Approach 1:
The patent segments the seismic data into multiple attributes (amplitude, phase, frequency, semblance) stored in separate three-dimensional volume data-sets. Each attribute can be processed and displayed independently, allowing high-resolution visualization without requiring computationally intensive processing of the complete data set at once.
Solution Approach 2:
The patent transitions from traditional two-dimensional seismic sections to three-dimensional volume data-sets with additional spatial dimensions. This allows the system to preserve and display waveform information in multiple dimensions simultaneously, achieving high resolution without computational distortion through sophisticated rendering techniques.
2Loss of information
If multiple three-dimensional volume data-sets are used to represent different attributes, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal sampling probe system that can interact with multiple three-dimensional volume data-sets representing different attributes (seismic amplitude, temperature, water-saturation). The same sampling probe interface and visualization tools can handle all attribute data-sets uniformly, reducing the complexity of managing multiple data types through standardized processing workflows.
3Measurement precision
If unmigrated input datasets are required, then resolution is improved, but adaptability decreases due to limitation with time-migrated data
Solution Approach 1:
The patent applies parameter changes through time migration processing that preserves resolution by transforming the data in a way that maintains the essential waveform information. The system can process both unmigrated and time-migrated data by adjusting processing parameters, making it adaptable to different data types while maintaining high resolution through sophisticated migration algorithms.

AI summary
Systems and methods for enhancing the resolution of a seismic data image displayed on a face of a sampling probe. The enhanced image represents a maximum resolution of at least a portion of the seismic data image. The seismic data image is enhanced by extracting seismic data that are perpendicular to a reflection surface that is closest to a center of the sampling probe and positioning the extracted seismic data in a visible planar face of the sampling probe.
