An experiment was run to determine the capillary pressure for a core in the laboratory. The core measurements from previous work were recorded in the table below, along with the capillary pressure and saturation values from the experiment. Later, data from well logs and well tests were evaluated, and the reservoir was determined to have an average porosity of 0.13 and an average permeability of 74 md. K (core) porosity (core) 100 md 0.16 IFT 50 dynes/cm Sw Pc (psi) 1 0.45 0.8 0.6 0.6 0.75 0.4 1.05 0.2 1.8 a. Construct a new capillary pressure curve to better represent the reservoir. b. Plot both capillary pressure curves on the same graph. Considering that capillary pressure curves can be thought of as an indicator of reservoir quality, does your new curve fit your new understanding of the reservoir quality?
