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

calculate:

a)Actual flow rate

b) Pressure drop due to skin

c) Flow efficiency
