Productivity index in horizontal wells

The study investigates the effect of reservoir and well parameters on the Productivity Index (PI) of a well. It analyses the effect of skin due to partial completion on Pl using the three partial well completion configuration of Brons and Mathews. Pl increases with increased well length and anisotropy value; also horizontal wells are better united for thin beds. The wells that are perforated at equal intervals along the well bore experience little or no skin effect, thereby enhancing productivity.
