Please assist with the preliminary steps before plotting the graph
Given the capillary pressure vs. saturation data for drill cuttings presented below use Purcell’s Pc-k relationship to determine the absolute permeability of the reservoir, k. Given IFT of a mercury-air system is 480 dynes/cm, the contact angle through Hg is 140o, the porosity is 0.29 and the lithology factor is assumed to be 0.216. (Hint: construct your 1/Pc2 vs. SHg plot and measure area under the curve by either breaking it up into geometric shapes (triangles and rectangles), or if you would like you can use some software package of your choosing.)
