Description: An alternative to the conventional test, is one that simply allows the well to flow into the closed wellbore after perforating (closed chamber test), which results in a pressure buildup. The pressure buildup data is collected for a period of hours or days, depending on the reservoir’s flow potential. These tests have been variously referenced to as: Slug Test, Surge Test, Perforation Inflow Diagnostic (PID), or Closed Chamber Test. Following a critical review of the literature published on these "unconventional" tests, we have developed a complete and systematic analysis that yields an estimate of initial reservoir pressure, permeability and skin. We have called this procedure Perforation Inflow Test Analysis (PITA).
