Industrial Applications - brief description
1. Integrated mineralogical-geochemical tool calculating petrophysical properties for the Formation Evaluation analysis.
The programs that use a non-linear optimization engine were designed to (A) optimize the bulk elemental composition of the sample with the quantitative phase analysis results to obtain individual mineral chemical composition (B) distribute minor and trace elements into minerals, and (C) calculate fundamental wireline log petrophysical parameters of individual minerals in an oil reservoir that can be used in wireline log mineral modeling program. When applied in Chevron ETC under the BestRockTM name, the program output produces the ComposerTM Excel Macro file that combines individual minerals into composite mineral end-points that can be chosen by the log analyst user based on weighted average concentrations of mineralogy, chemistry and associated petrophysical properties.
2. MinStatTM system of statistical calculations and a computer program as a tool for the mineral modeling in the Formation Evaluation.
The set of programs provide constraints describing relationships between minerals in an oil reservoir. The programs were designed for a manual or automatic calculation of mineral inequalities and for the multiple regression model for two or more (up to 10) mineral concentrations.
3. Methodology for CEC and TSSA measurement.
The bulk rock cation exchange capacity (CEC) and total specific surface area (TSSA) are mineral properties important in oil exploration.
The current methods of their measurement were adjusted and limitations determined.
An effect of water and EGME adsorption, and Co‑hexamine cation exchange was explained for samples rich in opals, kerogen, zeolites, gypsum, etc., and introduced as a routine approach in commercial applications.
4. Water Immersion Porosity (WIP) and Dual-Liquid Porosity (DLP) of shales.
Development of a technique for total and effective porosity measurements in gas shale samples. WIP and DLP are quick and simple methods based on a complete water and kerosene saturation combined with thermogravimetry and the mineral-chemical analysis (as above). When combined with gas adsorption techniques, the measurement reveals the wetability and pore size distribution in kerogen and mineral matrix. The WIP and DLP techniques avoid problems identified in other porosity measurement techniques available for shale samples (GRI, MICP).
5. PetroLog - reporting and calculation software for mineralogical and chemical data, including CEC, water adsorption, rock petrophysical properties, and clay minerals speciation. The software is used for daily routine reporting at Chevron ETC laboratories.
