A surface shut-in drillstem test (DST) procedure was used in an offshore volatile oil reservoir. Bottomhole shut-in devices were not used because of operational difficulties and anticipated hazardous problems. The type curve and Horner plots of the bottomhole pressures (BHP's) did not conform to classical theory. This paper explains the reasons and suggests a simulation procedure for the interpretation of data.
