Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seismic data interpretation methods face challenges in converting time-domain data to depth-domain data, particularly in complex geological areas, leading to inaccurate and time-consuming depth conversion processes that do not correct time-domain interpretation inaccuracies and are prone to sub-optimal uncertainty levels.

A software platform that concurrently displays time-domain and depth-domain interpretations along with a velocity model, allowing real-time manipulation and validation, enabling rapid convergence to an accurate velocity model and depth maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional iterative depth conversion procedures are used, then depth maps can be generated, but the process is time-consuming and does not allow for rapid correction of time-domain interpretation inaccuracies
Solution Approach 1:
The system dynamically updates depth-domain interpretations in real-time as velocity models change, allowing continuous refinement without traditional iterative delays. The depth conversion process responds dynamically to user manipulations of velocity models, providing immediate feedback and enabling rapid correction of inaccuracies.
Solution Approach 2:
The system provides immediate visual feedback by displaying updated depth maps as velocity models are manipulated. This real-time feedback loop allows interpreters to quickly assess the impact of velocity model changes and make rapid adjustments to correct time-domain interpretation inaccuracies, eliminating the delayed feedback inherent in traditional iterative processes.
2Reliability
If multiple depth-map realizations are generated through iteration, then uncertainty levels can be assessed, but the process is confined to velocity model variants and cannot take into account alternative time-domain interpretations
Solution Approach 1:
The system serves multiple functions simultaneously: it generates depth maps from velocity models, allows manipulation of both velocity models and time-domain interpretations, and provides real-time depth conversion. This multi-functionality enables comprehensive uncertainty assessment that incorporates both velocity model variants and alternative time-domain interpretations, far exceeding the capabilities of traditional confined iterative processes.
Solution Approach 2:
The system adds the dimension of time-domain interpretation manipulation to the traditional velocity model iteration process. By allowing simultaneous modification and visualization of both time-domain interpretations and velocity models with real-time depth conversion, the system enables exploration of a much broader solution space that incorporates multiple dimensions of interpretive uncertainty.
3Measurement precision
If velocity models are manipulated to improve depth conversion, then accuracy can be enhanced, but the process is slow and does not allow real-time visualization of outcomes
Solution Approach 1:
The system maintains continuous real-time depth conversion as velocity models are manipulated, eliminating the stop-start nature of traditional iterative processes. The depth maps update continuously alongside velocity model changes, providing uninterrupted visual feedback that maintains both accuracy enhancement and high productivity throughout the interpretation process.
