Well testing procedures are carried out on all newly drilled wells to determine the characteristics of the well and the formations it passes through. Most often the main goal of the well tests is to determine the productivity potential of a new well. Well testing involves an array of measurements and multiple types of downhole instruments for gathering information on the well characteristics.
Well tests are conducted to quantify well characteristics, production potential, and reservoir properties. Well tests are essential for exploration and production drilling, well maintenance, and geothermal field management. The tests ultimately help in optimal and sustainable utilization of the geothermal resource.
Well tests are normally conducted upon completion of drilling, but before removal of the drill rig so that the drill rig pump can be used for some of the tests.
