Geochemical Inversion System Using B Method for Yield Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current geochemical log processing methods face inconsistencies and overestimation issues when dealing with fluids and chemical components not described by relative yields, leading to confusion in analyzing reconstructed yields due to algebraic simplification and weighted vector mixing.
Innovation Solution
Introducing an unknown variable 'B' to represent the sum of chemical component yields, allowing for the determination of absolute yields and volumes, and using the 'B method' inversion system to correct inconsistencies by adding missing components and preventing overestimation of undetermined fluids and components.

Engineering Contradiction Analysis
1Adaptability or versatility
If relative yields are used to represent chemical components, then the geochemical data can be processed, but inconsistencies and overestimation occur when fluids or chemical components not described by relative yields are introduced
Solution Approach 1:
The patent introduces an unknown variable B as an intermediary element that represents the sum of all chemical component yields. This mediator allows the system to account for fluids and chemical components not explicitly described by relative yields, preventing their overestimation while maintaining mathematical consistency in the inversion system.
Solution Approach 2:
The patent transforms the traditional relative yield parameters into absolute yield parameters by incorporating the unknown variable B. This parameter change allows the system to distinguish between yields from known minerals and yields from unknown fluids or components, thereby improving the reliability of geochemical data analysis.
2Ease of operation
If algebraic simplification is applied to relative yields, then calculations are simplified, but confusion arises when analyzing reconstructed yields from the inversion
Solution Approach 1:
The unknown variable B serves as a mediator that separates the calculation simplification from information loss. By introducing B as an explicit term in the equations, the system maintains mathematical simplicity while preserving the ability to trace and analyze the contribution of each chemical component to the reconstructed yields.
3Productivity
If weighted vector mix of relative yields is used in the denominator, then the inversion system can be formulated, but confusion occurs when analyzing the results of reconstructed yields
Solution Approach 1:
The patent changes the parameter representation from relative yields to absolute yields by incorporating the unknown variable B. This transformation modifies the denominator of the inversion system to include B, allowing the weighted vector mix to be maintained for computational efficiency while improving the interpretability of reconstructed yield results.

AI summary
Systems, media, and methods for determining relative geochemical data are provided. Measurement data may be received that is indicative of relative yields of a plurality of chemical components in a rock formation. First absolute yields of at least a portion of the plurality of chemical components in a presence of 100% of a first volumetric component in the rock formation may be determined. Second absolute yields of at least a portion of the plurality of chemical components in a presence of 100% of a second volumetric component in the rock formation may also be determined. A volume of the first volumetric component, a volume of the second volumetric component, and a sum of yields of the plurality of chemical components may be determined using the first and second absolute yields and the relative yields.
