Abstract
Four pressure fall-off pressure transient tests were conducted in a well being stimulated by high pressure injection. The tests were analyzed with a technique based on fractional flow in a composite reservoir. The results show the progress of the stimulation process as the measured reservoir properties change from test to test. Novel techniques for analysis of pressure transient tests are demonstrated. The reason for the very large wellbore storage effect usually found in injection fall-off tests is discussed and considered in the analysis.
