Dynamic-Underbalance Perforating Overcomes Environmental …

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. WebSep 12, 2005 · A new approach produces a well dynamic underbalance (the transient underbalance just after creating the perforation cavity). By basing the job design on the properties of the reservoir, wellbore, and gun string, the technique consistently minimizes perforation damage and thus maximizes productivity. irrational fear of bugs
