The application of extreme overbalance perforating, by Oryx Energy Co., is consistently outperforming the unpredictable, tubing-conveyed, underbalance perforating method which is generally accepted as the industry standard. Successful results reported from more than 60 Oryx Energy wells, applying this technology, support this claim. Oryx began this project in 1990 to address the less-than-predictable performance of underbalanced perforating. The goal was to improve the initial completion efficiency, translating it into higher profits resulting from earlier product sales. This article presents the concept, mechanics, procedures, potential applications and results of perforating using overpressured well bores. The procedure can also be used in wells with existing perforations if an overpressured surge is used. This article highlights some of the case histories that have used these techniques.
