Definition - What does Well Testing mean?
Well Testing is the execution of the set of activities of planned data acquisition for broadening the understanding and knowledge of the properties of reservoirs containing hydrocarbons. It provides information about the state of a well. The main objective of Well Testing is to identify the capacity of reservoirs to produce hydrocarbons like natural gas and oil. The data gathered during Well Testing involves pressure and the volumetric flow rate observed in a particular well. Well Testing requires the right technology, planning and implementation in order to gather information about a particular well.
Petropedia explains Well Testing
Well Testing determines fluid properties, reservoir pressure, areal extent, flow rates, vertical layering, drawdown pressure, permeability, formation damage, productivity index and much more. The dynamic reservoir properties can be measured using a well test. It also allows the operators to extract fluid samples from the reservoirs in order to observe changes in the properties of the reservoir fluids and in the composition between the wellhead and the perforation. The information gathered is essential for the prediction of the reservoir and well completion. By measuring the flow rates and pressures physically, Well Testing offers large scale measurement of permeability. It also provides the transcendent means of evaluating the ability of reservoirs to transmit fluids.
