Optimizing Underbalanced Perforation Performance, a New Model to Precise Adjustments of Downhole Condition

Perforating creates a low-permeability crushed zone in the formation around the perforating tunnels that also constitutes a<br>flow restriction, which can impair the well's productivity or injectivity. A precisely designed underbalanced perforation job<br>could effectively minimize or remove perforation damages and thus optimizes the production rate.
