Fluid viscosity, μ₀ = 1.8 cp
Total compressibility, cₜ = 0.000013 psi⁻¹
Drainage area, A = 640 acres (rₑ = 2,980 ft)
Wellbore radius, r = 0.328 ft
Skin factor, S = 2

Answer 1

The Intensity of Pressure Ratio (IPR) of a vertical well in an undersaturated oil reservoir can be determined using the generalized Vogel equation.

Step-by-step explanation:

The Intensity of Pressure Ratio (IPR) of a vertical well in an undersaturated oil reservoir can be determined using the generalized Vogel equation. The equation is:

q = (khΔp)/(cμB)

where:

• q is the flow rate (bbl/day)
• k is the effective horizontal permeability (md)
• Δp is the pressure drop across the reservoir (psi)
• c is the total compressibility (psi^-1)
• μ is the fluid viscosity (cp)
• B is the fluid formation volume factor (bbl/STB)

Given the provided data, you can substitute the values into the equation to calculate the IPR of the well.
