Inflow Performance Skin
A well is drilled in a clean sandstone formation. The DLL and FDCCNL logs indicted a productive horizon from TVD A sidewall core sample indicates an average permeability of in this horizon and the PVT analysis confirms of Oil viscosity is
a Assuming the drainage radius is and the wellbore radius is what is the steady state productivity index PI or J for this well?
b Draw the inflow performance curve for this well if the initial reservoir pressure is psi.
c If a subsequent well test confirms an insitu skin of what is the PI for the well taking this skin into account?
d Draw the inflow performance curve for this well taking the positive skin into account.
