Solution Overview

Problem

Conventional seismic interpretation tools provide a static view of seismic data, making it difficult to interpret when there are data gaps due to null or poor quality seismic traces across multiple 3D seismic surveys, which reduces efficiency and requires manual rearrangement of data.

Innovation Solution

A method to adjust seismic section boundaries automatically or manually within a graphical user interface to remove or minimize data gaps in overlapping 3D seismic surveys, optimizing the visualization and interpretation of seismic data by identifying live seismic traces and adjusting boundaries accordingly.

1Ease of operation

If conventional seismic interpretation tools provide a static view of seismic data, then the tool complexity is reduced, but data gaps due to null or poor quality seismic traces make interpretation difficult and require manual rearrangement

Engineering Contradiction:

Improveseismic interpretation efficiencyVSAvoiddata gaps in seismic surveys

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent implements dynamic boundary adjustment that allows seismic section boundaries to be automatically or manually repositioned based on data quality assessment. The system dynamically evaluates trace quality metrics and adjusts the display boundaries to exclude regions with null or poor quality traces, transforming the static view into an adaptive, quality-aware presentation that eliminates data gaps while maintaining ease of operation.

Inventive Principle:

Principle #15Dynamics

2Reliability

If manual rearrangement of seismic data volumes is performed to remove data gaps, then data quality is improved, but productivity and user efficiency are reduced

Engineering Contradiction:

Solution Approach 1:

The system implements self-service functionality by automatically assessing trace quality across the seismic survey volume and autonomously adjusting section boundaries to eliminate data gaps. The software evaluates data quality metrics, identifies regions with null or poor quality traces, and repositions boundaries without requiring manual intervention, thereby maintaining high data quality while preserving interpretation productivity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent changes the boundary parameters of seismic sections dynamically based on trace quality assessments. By adjusting boundary positions according to data quality parameters, the system automatically optimizes the display to exclude poor quality regions, achieving reliable data presentation without the time-consuming manual rearrangement process.

3Device complexity

If seismic section boundaries are fixed across multiple 3D seismic surveys, then device complexity is minimized, but data gaps appear in overlapping survey areas

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent applies segmentation by dividing the seismic survey area into multiple sections with adjustable boundaries. Each section can be independently positioned to optimize data coverage and eliminate gaps in overlapping survey areas. This segmentation approach allows the system to manage complexity through modular boundary control while ensuring complete data representation across multiple 3D surveys.
