Abstract:
We are using finite element models to first characterize the regional-scale geohydrology, and understand how petroleum migrates from source rock to reservoir trap on the western side of the Los Angeles basin. Specifically we are interested on how the opening/closing of faults influence large-scale fluid migration patterns and rates, fluid pressure, and heat flow within the basin. Secondly, we are developing smaller-scale flow models to better understand the role of transient geohydrologic changes, to evaluate the effect of the NIFZ on local heat flow, and characterize structural controls on clastic diagenesis near the fault. In addition, we have built a two-phase flow model that can predict migration patterns of petroleum in the deep subsurface as an immediate response to the opening/closing of NIFZ. Ultimately we hope to couple these separate-flow models with chemical reactions and predict patterns and timing of diagenetic alteration along faults in a transpressive basin environment.
