Testing in an exploration or appraisal well is directed at estimation of reserves in communication with that well,in addition to well productivity. Testing in a production well also monitors the effects of cumulative production on the formation. Tests basically consist of a series of measurements of pressures, fluid flows and temperatures down hole (PVT) in a controlled sequence of ?flowing? and ?shut-in? periods for recovery of stable reservoir conditions. The time taken to recover is also recorded. Various forms of well stimulation may also be built into the sequence. Tests will also include the functioning of well equipment.
