Engineering Contradiction Analysis
1Device complexity
If one-dimensional simulation methods are used to estimate organic matter content, then the simplicity of the method is maintained, but the accuracy of organic facies characterization and the ability to assess production, preservation, and degradation processes deteriorate
Solution Approach 1:
The patent transitions from one-dimensional well-level simulations to multi-one-dimensional simulations that integrate data across multiple wells and spatial dimensions. This dimensional expansion enables comprehensive characterization of organic facies and assessment of production, preservation, and degradation processes while maintaining methodological systematicity.
2Measurement precision
If multiple equations and environmental variables are incorporated to improve organic carbon content estimates, then the accuracy of organic matter characterization is improved, but the complexity of the simulation process increases
Solution Approach 1:
The patent segments the simulation process into distinct modules: organic matter production simulation, preservation process simulation, degradation process simulation, and maturation level simulation. Each module employs specific equations and environmental variables appropriate to its function, allowing complex processes to be managed through systematic decomposition while maintaining overall integration.
Solution Approach 2:
The patent develops a universal simulation framework that can handle multiple organic matter types (marine, terrestrial, mixed) and various environmental conditions through a single integrated system. The methodology universally applies to different sedimentary basins and geological contexts, reducing the need for multiple specialized approaches.
3Reliability
If multi-one-dimensional simulations are implemented to accurately characterize organic facies, then the quality of oil exploration decision-making is improved, but the data processing requirements and computational demands increase
Solution Approach 1:
The patent extracts and isolates key parameters and relationships from complex geological data through standardized simulation equations. By separating essential information (organic matter content, preservation factors, degradation rates) from raw data complexity, the system enables reliable decision-making while managing data processing requirements through focused parameter extraction.

AI summary
The invention relates to the method of exploration at well level (one-dimensional) of the content and quality of organic matter in source rocks in marine environments. The method for determining the content and maturation of organic carbon by (multi)one-dimensional simulation makes it possible to estimate the production, preservation and degradation of this carbon in a given well (or multiple wells) located in a sedimentary basin, in order to characterize the organic facies present in the marine environment.
