Dynamic underbalance perforating with the PURE technique

WebAn enhanced technique known as dynamic underbalanced (DUB) perforating creates a negative pressure differential or underbalance, causing fluid to move toward the wellbore, even in an initial overbalanced static condition. DUB is important to create open, undamaged perforations and optimize well productively. WebThe underbalance pressure condition is not surprising. Progressive perforation clean-up with increasing underbalance is intuitive and has been well noted by previous investigators. This study extends the concept by making reference to a peak dynamic underbalance pressure occurring during perforating. data entry cheat sheetWebA wide range of downhole scenarios including static underbalance and/or dynamic underbalance and the interaction between them, as well as overbalance conditions were considered in this study.
