Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for decomposing complex formation logging data into simpler components for efficient transmission and analysis often result in imperfect fits and lack of correlation with underlying physical events, due to overlapping Gaussian components and multiple possible solutions.
Innovation Solution
The method decomposes complex distributions into simpler components by minimizing both mismatch and overlap between components, using an error function that balances these factors, and employs multi-objective optimization techniques such as evolutionary algorithms or scalar optimization with relative weights to ensure physically meaningful results.

1Productivity
If complex formation logging data is decomposed into simpler components for efficient transmission and analysis, then data transmission efficiency and analysis speed are improved, but the decomposition may produce overlapping Gaussian components that do not accurately represent underlying physical events
Solution Approach 1:
The patent segments complex formation logging data into multiple simpler Gaussian components, each representing distinct physical events or processes. This segmentation enables efficient transmission by sending only the parameters of individual Gaussian components rather than the entire complex dataset, while maintaining the ability to reconstruct the original data distribution accurately.
Solution Approach 2:
The patent transforms the complex data representation by changing parameters from the original raw data format to a set of Gaussian component parameters (amplitude, mean, standard deviation). This parameter transformation allows for more compact data transmission while preserving the essential characteristics of the formation data through the mathematical properties of Gaussian distributions.
2Adaptability or versatility
If multiple Gaussian components are used to represent complex distributions, then the flexibility and adaptability of the model is improved, but the risk of overlapping components and multiple possible solutions increases
Solution Approach 1:
The patent implements an iterative optimization process with feedback mechanisms that adjust Gaussian component parameters based on how well they fit the target distribution. The algorithm continuously evaluates the decomposition quality and refines component parameters, providing feedback loops that converge to stable, unique solutions that accurately represent the underlying physical events.
Solution Approach 2:
The patent employs dynamic optimization algorithms that adaptively adjust the number, position, and parameters of Gaussian components during the decomposition process. This dynamic approach allows the model to flexibly accommodate different data distributions while converging to reliable, unique solutions through iterative refinement rather than static assumptions.
3Speed
If decomposition is performed without minimizing overlap between components, then the processing speed is improved, but the physical interpretability and accuracy of the components deteriorates
Solution Approach 1:
The patent applies preliminary ordering and positioning of Gaussian components before final parameter optimization, pre-arranging components in a sequence that minimizes potential overlap. This preliminary action reduces the computational burden during subsequent optimization while ensuring that components are properly separated and physically interpretable from the outset.
