Perforating and Pressure Measurement Techniques To Maximize Production and Wellsite Efficiency

Modern perforating techniques designed to maximize production seem as varied as the wells they are applied to. However they have one trait in common: an instantaneous pressure drawdown (reverse pressure) is applied to surge the perforations clean and create the highest effective shot density possible. The pressure drawdown lends itself to a pressure buildup test immediately thereafter. This paper discusses reverse pressure surging techniques with casing, thru-tubing, and tubing conveyed perforating guns along with a discussion of the capabilities and versatility of the Measurement While Perforating (MWP*) and Measurements After Perforating (MAP*) buildup testing techniques.
