Comparison Between Perforating System And Study Of Perforating Efficiency

Abstract

The major objective of perforating is to provide an effective flow communication between wellbore and formation, and achieve adequate well productivity. Perforating techniques and equipment that are used play an important role in determining the production that results. This paper describes the various perforating system used in the oil industry, with tile guns and techniques that are commonly used, applications and limitations of each. Studies also include factors that affect the well productivity as well as other parameters that influence the decision making in chosing the right perforator/gun under existing conditions. Actual data from a local oil field are used as a case study and the performance of different shaped charge are simulated using the Schlumberger SPAN OIL software. The results agree with the previous findings, guns having high shot density. deepest penetration, best phase angle under reversepressure condition give the best productivity.
