Abstract: A method is provided for evaluating the quality of a hydraulic fracture treatment performed in a completed wellbore penetrating a subterranean hydrocarbon-bearing formation. The method is initiated by creating a pressure differential or utilizing an existing pressure differential between the wellbore and the formation and placing a lower packer and an upper packer in the wellbore. The lower and upper packers are positioned in the wellbore at or near the bottom of the producing interval to enclose one or more lower perforations within a wellbore chamber sealed to the remainder of the wellbore. Pressure values of the wellbore chamber are measured for a predetermined time period and then the lower and upper packers are repositioned to enclose the next one or more perforations in sequence within a new wellbore chamber. This procedure is repeated until pressure values have been measured in all wellbore chambers enclosing perforations of interest.
