Underbalance criteria for minimum perforation damage
Journal Article

· SPE Drilling and Completion
A simple viscous drag force equation has been applied to single-shot laboratory perforation/flow experimental data to obtain perforation damage skin vs. underbalance. The equations are applicable for oil wells in consolidated, nonsanding formations and are a function of reservoir porosity, permeability, and diameter of the perforation tunnel in the rock. The equations are independent of oil compressibility and viscosity. The dependency on perforation diameter suggests that larger charges are more damaging than small charges and that big hole charges are more damaging than equal-size deep penetrating charges. The equations can be used to calculate an optimum underbalance or a single-shot perforation skin for less than optimum underbalance. The single-shot skin can be used in well-flow analysis simulators to obtain a well perforation skin.
