WebFeb 1, 2024 · The effect of a dynamic underbalance (dub), therefore, is more efficient damage layer breakdown and tunnel cleanup. In modern perforating operations, it is often a combination of both static and dynamic underbalance that is designed into the job to optimize the perforation cleanup and maximize productivity. 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.
