PROBLEM
A thick, subsurface formation contains an oil accumulation above an aquifer. A core sample porosity and k mD from Well# in the formation has the capillary pressure curve shown in the figure below. Well logs and core analysis establish the WOC at ft below sea level. The following additional data at formation conditions are available:
Oil density: lbft
Water density: lbft
Oilwater interfacial tension IFT: dynescm
Oilwaterrock contact angle: deg
Calculate:
a The connate water saturation Swc
b Depth of the Free Water Level FWL
c Thickness of the transition zone.
d Depth to reach oil saturation. SOLVE ALL PARTS AND CALCULATE TO FIND FINAL ANSWERS
PROBLEM
The formation in Problem # has a porositypermeability transform of kk in Darcys A core sample from Well# in the same formation shows a porosity of Assuming the same depth of the FWL what is the depth of the oil saturation in Well#SOLVE
