A test of the well’s producing potential usually done during the initial completion phase. Test made to determine the daily rate of oil, gas, and water production. Production testing is carried out after electric logging, especially if the results of these are not conclusive. The testing may last a couple of weeks, cost considerable money and is meant to provide further details of the main gas content and subsurface information.

A combination of a potential test and a bottomhole pressure test the purpose of which is to determine the effects of different flow rates on the pressure within the producing zone of the well to establish physical characteristics of the reservoir and to determine the maximum potential rate of flow.

A mathematical means to explain the ability of a reservoir to deliver fluids to the wellbore.

The productivity index (more briefly PI) takes into account the reservoir characteristics at the inlet of the well, through the specification of a relation between the inlet total flow rate QT, the well inlet pressure P and the reservoir pressure PG.

The degree that the well can produce hydrocarbons

Productive wells are producing wells and wells capable of production. A productive well is an exploratory or a development well that is not a dry well

Productive capacity is the maximum output you could achieve with your current production equipment when it is working for the maximum practical number of hours and with the maximum efficiency and minimum down and change over times
