Hydrocarbon Migration Petroleum Geology Class 745 Spring 2002 Istvan Csato University of South Carolina Department of Geological Sciences
Buoyancy Hydrostatic condition:
Capillary Pressure Capillary pressure Condition of migration
Migration Critical height of oil stringer:
Migration Darcy’s law: specific discharge [m/s] permeability of the matrix [m2] viscosity of oil [kg/m/s] mean radius of the rock pores [m] tortuosity porosity oil saturation
Migration Vertical flow: Updip flow at 2o slope: qo=0.4 cm/year qo=11.3 cm/year
Origin of Fluid Flow 1. Restricted-compaction 2.Meteoric Water Recharge
Fluid Flow - Compaction Fluid Flow Compaction Mass conservation equation: Fluid flow equation (Darcy’s Law):
Primary and Secondary Migration as a function of rock permeability Secondary Migration Primary Migration
