Hydrostatic condition: Buoyancy

3
Capillary Pressure Capillary pressure Condition of migration

4
Migration Critical height of oil stringer:

5
Migration

6
Darcy’s law: specific discharge [m/s] permeability of the matrix [m 2 ] viscosity of oil [kg/m/s] mean radius of the rock pores [m] tortuosity porosity oil saturation Migration

7
Vertical flow: q o =11.3 cm/year Updip flow at 2 o slope: q o =0.4 cm/year

8
Hydrodynamic Conditions

9
Hydrodynamic Traps

10
Compaction
