Question

(application in tormation evaluation) The variations of pore pressures with depth are showr for two reservoirs (A and B) in a sedimentary basin. Bases on your Fluid Mechanics knowledge, determine if each reservoir is over-pressured, under-pressured, or normally pressure. Also determine the saturating liquid (dry gas, oil, fresh water, or brine). Pore pressure (psi) 4000 5000 6000 7000 8000 Pore pressure (psi) 1000 1500 2000 2500 3000 6000 7000 8000 9000 10000 11000 12000 13000 4000 5000 6000 7000 8000 CA
