 Q2) From this data: Oil column thickness = 25 ft, po

Q2) From this data: Oil column thickness = 25 ft, po = 0.5 cp. Perforated zone thickness=180 in, Radius of drainage area =660 ft. Total pressure drop = 1000 psi, well bore radius = 0.375 ft. Bo (oil formation volume factor) = 1.4 RB/STB, Perforating diameter = 2 in, perforating (shots) density = 4 perforation (shots)/ft, permeability=0.1 d. Jet guns used to perforation operation, and the bullet penetrate the casing and cement only, and perforation phase in one side. 1. Actual flow rate equal to: 1500-1600 2500 2550 1100-1150 2000-2050 2. Pressure drop due to skin equal to: 490-550 600-650 200-250 340-400 3. Flow efficiency equal to: 07-0.8 0.4-0.5 0.1-0.3
