Problem 3 The plugs from the core sample in Homework 2 were analyzed through conventional analysis. In Homework 2, you determined the porosity and permeability of each core plug. The following steps have been also taken during the experiments: The core plug was weighed as received (W AR ). The water and oil ( = 0.85 g /cc) were extracted from the core plug and volume of the ρ water ( V w ) was recorded. The core plugs were dried and were saturated with water. Each saturated core plug was placed in a closed container whose bottom consists of a porous plate. A constant air pressure was applied and when equilibrium was attained, the core plug was re- weighed. The air pressure was gradually increased until the sample weight reached a minimum. The minimum sample weight ( W Min ) was recorded at the conclusion of each experiment. The results of experimental measurements are given below. You are asked to determine saturations as received and irreducible water saturation for each core plug and plot them against the depth.
