drainage area. The formation net pay is 75 ft thick with the net to gross ratio of 0.9 and has a
porosity of 6.5%. The formation permeability values are 2 md and 15 md in vertical and horizontal
directions, respectively with the relative permeability to oil of 0.82. The oil has a viscosity of 0.55
cp and the formation volume factor is 1.22 bbl/STB. Earlier test conducted at this well resulted in
the calculation of a skin value of 0.8. The correction factor for wellbore friction is 1.0.
● Determine the Productivity Index (PI) for this well.
