Chronostratigraphic Modeling for Reservoir Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current geological modeling and mapping techniques face challenges in correlating geologic strata over large distances due to limited and disjointed lithostratigraphic data, making it difficult to create a comprehensive chronostratigraphic framework that accounts for the age and spatial coordinates of subsurface data.
Innovation Solution
A chronostratigraphic modeling system and method that involves scanning and digitizing well logs to create a database with spatial coordinates (x, y, z) and age-tagged data points, allowing for the normalization and correlation of data to establish a chronostratigraphic framework, enabling the visualization and querying of geologic data by age and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If lithostratigraphic correlation methods are used, then mapping can be performed within a common basin, but the method fails to account for changes in strata over large geographic distances
Solution Approach 1:
The patent transitions from lithostratigraphic parameters (rock type, composition) to chronostratigraphic parameters (age, time) as the basis for correlation. By changing the fundamental parameter used for correlation from lithology to age, the system can reliably map strata across large geographic distances where lithostratigraphic methods fail due to lateral variations in rock composition.
2Quantity of substance
If traditional well log data are used, then discrete subsurface information is obtained, but the data are limited, disjointed and difficult to correlate chronostratigraphically
Solution Approach 1:
The patent creates a universal chronostratigraphic framework that can accommodate multiple data types (well logs, seismic data, outcrop data) from different sources and formats. This unified age-based framework serves multiple functions: correlating strata across regions, integrating disparate data types, and providing a common reference system that simplifies what would otherwise be complex disjointed correlations.
Solution Approach 2:
The patent introduces a chronostratigraphic framework as an intermediary layer between discrete well log data points and regional geological mapping. This framework acts as a mediator that connects isolated data points by providing age correlations, allowing information to be transferred and integrated across different locations and data types without direct point-to-point correlation.
3Reliability
If age-tagged data points with spatial coordinates are integrated, then comprehensive chronostratigraphic framework can be established, but data processing and database organization complexity increases
Solution Approach 1:
The patent segments the geological data into discrete, standardized data points each with specific attributes (age, spatial coordinates, formation characteristics). By breaking down continuous geological information into segmented, digitized units with standardized metadata, the system can process and organize complex chronostratigraphic data in a structured manner that maintains accuracy while enabling computational management.
