What are the testing requirements for new wells that are drilled?
An initial reservoir pressure (Pi) test is required prior to production from any zone. A valid DST on the zone is acceptable for a measurement of initial pressure. Otherwise, the company may run a static gradient following initial completion, once wellbore dynamics have stabilized. All gas wells require an AOF test within six months of initial production, if not already done prior to pipeline tie-in. A single point test is often adequate, however a multi-point test is preferred. In-line testing is preferred, to reduce gas flaring, as long as line pressure does not restrict the well to a low flow-rate. A calculation of both sandface and wellhead AOF values is required.
