Project ObjectiveProject ObjectiveBetter prediction of interwell reservoir heterogeneity – which may lead to increased production from California’s heavy oil fields


Tasks Measure flow properties & analyze

fractal structure of property distributions

Characterize geology (reservoir geometry, continuity, and scale) of Coalinga area using outcrops and cores

Develop 3-D computer models and distribute permeability

Perform simulation of steam flooding at West Coalinga field
