Abstract

Well-bore storage may dominate the bottom-hole pressure profile of a well particularly for the short time situation, The dominance may be strongly accentuated in cases where reverse flow into a passive sand or casing leakage down-hole cannot be isolated from the test zone. This analysis shows that reverse flow of fluid in a well- bore has a retarding effect on pure storage phenomenon. Thus in effect, type-curve analysis of bottom-hole pressures as a means of evaluating petro-physical properties of a reservoir sand may be rendered unreliable if reverse flow effect is not properly considered.
