Dynamic underbalance perforation
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. WebThis variation in wellbore pressure is reflected in relation to the transient underbal-ance, and it is the maximum dynamic underbalance—not the initial underbalance—that governs perforation cleanup. Figure 56 shows the results of Tests 1 through 4 with the same charge and starting at an ini-tial underbalance of 1,000 psi.
