1. Construct IPR of a vertical well in an undersaturated oil reservoir. The following data are given: The following data are given: Effective horizontal permeability, k=14md Pay zone thickness, h=47ft Reservoir pressure, pr=2,764psi Fluid formation volume factor, Bo=1.12bbl/stb Fluid viscosity, 0=0.9cp Drainage area, A=40 acres Wellbore radius, rw=0.328ft Skin factor, S=3 and 0 Constant pressure at the boundary 2. The following data are given: Reservoir pressure, pr=2,450psia Tested flowing bottom-hole pressure in Well A, pwf=1,500psia Tested production rate from Well A, q=324STB/ day Pay zone thickness, h=49ft Fluid formation volume factor, Bo=1.17 Fluid viscosity, o=0.87cp Wellbore radius, rw=0.328ft Drainage area, A=80 acres No flow boundary a. Calculate the Productivity Index of the well A. b. If the permeability is 15mD, what is the skin factor of the well? c. If the skin factor is 0 , what is the reservoir permeability? 3. The following data are given: Reservoir pressure: 2,456psi Drainage area: 80 acres Oil viscosity: 0.92cp Oil formation volume factor: 1.16bbl/STB Wellbore radius: 0.328ft Skin factor: 3 a. Construct IPR of the well (Pr=2,456psi)
