WebJul 1, 2004 · PURE perforating is a patented method developed by Schlumberger employing a dynamic underbalance to remove perforating debris, minimise crushed zone damage … 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.
