Question 4 (30 Points): A well was drilled and cored. The core was sent to a service company to have the capillary pressure measured along with other core properties. The following Laboratory Capillary Pressure Data were measured from the core sample at laboratory conditions. The laboratory conditions: Air-Water-Quartz Contact Angle 15.0 Air-Water Interfacial Tension 75.0 dynes/cm Core Permeability 65.0 md Core Porosity 0.12 fraction Core Irreducible Water Saturation 0.15 fraction degrees The laboratory measured capillary pressure data are: Labs. Lab.P. Fraction psi 0.152 62.47 0.350 9.90 0.450 8.42 0.745 6.40 1.000 S.55 Convert these laboratory measurements to the appropriate reservoir capillary pressure data. The reservoir conditions are: Oil-Brine Contact Angle 40.0 degrees Oil-Brine Interfacial Tension 26.0 dynes/cm Core Permeability 65.0 md Core Porosity 0.12 fraction Core Irreducible Water Saturation 0.15 fraction What is the top of transition zone at this well location (only the top is required)?
