Abstract

Perforation is a hole to provide a good and effective communication channel between the wellbore and the productive zone for an optimum well productivity. To obtain optimum gain in perforated well productivity, perforations must be deep enough to overcome formation damage or barrier caused by drilling operations. Very deep, small diameter perforations will be difficult to clean effectively. The primary objective of perforation for a natural completion is to produce deeper penetration depths to overcome formation damage, higher shot density to reduce pressure drop around the perforations and to increased perforation efficiency. For a natural completion, penetration depth and shot density are very important geometrical factors, followed by phasing. Perforation diameter is relatively insignificant [1].
