Drill stem Testing Drillstem Testing (DST) is a valuable tool in the oil and natural gas extraction process. DST is a process to establish the productive capacity, pressure, permeability or extent of an oil or gas reservoir. Drill stem testing is basically a flow test, which is performed on isolated formations of interest to determine the fluids present and the rate at which they can be formed.
