Abstract
A method of performing a rock core flow performance test includes increasing a pressure applied to at least one surface of the rock core to a first pressure, measuring the pressure on a wellbore facing axial end of the rock core to determine a time interval over which the measured pressure drops from a second pressure to a third pressure, and determining a high pressure production ratio of the rock core based on the time interval.
