Abstract: An apparatus may include a tubular, a first isolator connected to the tubular and configured to engage an interior surface of the wellbore, a first pressure gauge connected to the tubular and configured to take multiple pressure readings over a period of time, and a first perforation gun connected to the tubular without compromising the communication of fluid through an inner flow channel of the tubular. A method may include placing the apparatus in a wellbore, and actuating the isolator to provide isolation of a first zone in a formation. The method may include activating the perforation gun to provide fluid communication between an annulus of the wellbore and the zone in the formation. The method may include allowing the pressure gauge to take a plurality of pressure readings over a period of time. Based on the pressure readings, the method may include determining a formation characteristic.
