Multi-Stack Seismic Analysis for Lithology Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seismic data analysis workflows are limited as they often rely on a single offset stack or angle stack, missing geological attributes present in other volumes, which can lead to incomplete interpretations of lithology and stratigraphic architecture.
Innovation Solution
A computer-implemented method and system that analyze attributes by obtaining attribute volumes from multiple offset and angle stacks, flattening them according to various metrics, generating slices, and identifying geologic features through sequential analysis to leverage discrepancies and similarities across these volumes.

Engineering Contradiction Analysis
1Productivity
If a single offset stack or angle stack is selected for analysis, then the interpretation workflow is simple and fast, but geological attributes present in other volumes are missed leading to incomplete interpretations
Solution Approach 1:
The patent merges multiple offset stacks and/or angle stacks into a unified analysis framework. The system combines data from multiple volumes, allowing interpreters to analyze geological features across different offset and angle domains simultaneously, thereby capturing comprehensive geological attributes without sacrificing workflow efficiency
Solution Approach 2:
The patent creates a multi-functional analysis system that can handle multiple offset stacks and angle stacks within a single workflow. The system provides universal capabilities to analyze different geological attributes across multiple volumes, enabling a single interpretation workflow to serve multiple analytical purposes
2Loss of information
If multiple offset stacks and angle stacks are analyzed individually, then more geological attributes are captured, but the interpretation workflow becomes complex and time-consuming
Solution Approach 1:
The patent merges the analysis of multiple offset stacks and angle stacks into a unified system where data from different volumes are integrated and analyzed together. This combination approach captures comprehensive geological attributes while maintaining a streamlined workflow through centralized processing and coordinated display of multiple volumes
Solution Approach 2:
The patent introduces an intermediary integrated system that mediates between multiple offset stacks and angle stacks. This intermediary framework coordinates the analysis across different volumes, managing the complexity of multi-volume analysis while preserving access to diverse geological attributes through a unified interface

AI summary
Geologic information may be extracted from multiple offset stacks and/or angle stacks. Offset stacks and/or angle stacks may be received that represent energy that has propagated through a geologic volume of interest from energy sources to energy receivers. Attribute volumes associated with individual source-receiver offsets and/or source-receiver angles may be determined based on corresponding offset stacks and/or angle stacks. For individual offset stacks or angle stacks, corresponding sets of geologic features represented in the attribute volumes may be identified. The sets of geologic features corresponding to the different offset stacks and/or angle stacks to may be compared to determine discrepancies and/or similarities between the sets of geologic features corresponding to the different offset stacks and/or angle stacks. Stratigraphic interpretations, stratigraphic predictions, and/or other interpretations and/or predictions may be determined based on causes of the discrepancies and/or similarities.
