2. Calculate the productivity index (J) of a vertical well in an oil reservoir considering a steady-state and transient flow. Porosity: o= 0.19 Effective horizontal permeability: k = 8.2 md Pay zone thickness: h = 53 ft Reservoir pressure: Pe or p = 5,651 psia Bubble-point pressure: Pb = 50 psia Fluid formation volume factor:, B, = 1.1 Fluid viscosity: Mo = 1.7 cp Total compressibility, c, = 0.0000129 psi Drainage area: A=640 acres (re = 2,980 ft) Wellbore radius: rw = 0.328 ft Skin factor: S=0 3. Determine PI for an ideal case given that static reservoir pressure Pr is 2400 psi, oil flow rate is 200 bpd, water flow rate is 300 bpd and bottom hole flowing pressure is 2200 psi. 2.
