The class focuses on the role of sedimentary and structural heterogeneities in controlling porosity, permeability, and fluid flow in the subsurface.ÒÒTopics include controls on conventional and unconventional reservoir quality and performance, evaluating caprock integrity, and the influence of faults and fracture networks on fluid flow.ÒÒApplications to petroleum geology, petroleum engineering, carbon sequestration, and hydrology.ÒÒThere is a mandatory field trip associated with the class, which involves camping and moderately strenuous hiking on uneven ground.ÒÒ Shares lecture with ERTH 461, with additional expectations for graduate credit.
