Question

8.4- The oil–water capillary pressure data were measured in the laboratory using Isopar-L and water on a reservoir rock core sample originating from a Middle Eastern field. However, the contact angle and IFT for the reservoir oil and formation water in the reservoir were not the same as those measured for Isopar-L and water. Using the following data, convert the capillary pressures from laboratory conditions Please see the text book for provided table Report the Pc with water saturation of 0.65 at Capillary pressure of 500 kN/m^2 in kN/m^2

Explanation / Answer

Pc=Po-Pw

Pc=500kN/m^2

Pw=0.65

Po=?

now, Pc=Po-Pw

500=Po-0.65

500+0.65=Po

500.65
