Print this pageThree Dimensional Basin Reaction-Transport-Mechanical Modeling: A Comprehensive, Fully Coupled Computational Approach
ORTOLEVA, PETER J.
A three dimensional basin model has been developed that accounts for the coupled diagenetic reaction-transport- mechanical processes believed to be key to the evolution of a sedimentary basin. These include grain growth/dissolution/nucleation, pressure solution, fracturing, continuous irreversible rock deformation, and single- and multi-phase fluid reactions and transport. The model is a fully coupled, finite element/difference, three dimensional implementation.
Our model is used to predict the evolution of porosity, permeability, fluid composition, and phase across the basin over the 100 million year time frame. Example studies of the Anadarko, Piceance and Midland basins will be reviewed in the light of contemporary thought on compartmentation and fractured reservoirs.
