... perforation conditions. These results were integrated with mud testing and operational considerations to create an overall completion design for the field. Section 4 tests were performed at static overbalance, static underbalance and dynamic underbalance conditions scaled to field conditions using either mud...

... significantly better than conventional perforations in gas reservoirs. The robust statistical confidence associated to this productivity increase will be explicitly discussed and presented in this paper. upstream oil & gas static underbalance completion installation and operations thickness...

... Abstract Perforating underbalanced has become the primary means of removing perforation damage and maximizing productivity through a cased and perforated completion. The level of static underbalance (wellbore to pore pressure difference prior to perforating), considered the critical parameter...
