DST TEST STRING SHEMATIC AND DETAILED DESCRIPTION:
Drill-stem testing (DST) is a procedure used in the petroleum industry to determine the productive capacity,and permeability of a potential petroleum reservoir zone. It is comprised primarily of a flow test on isolated rock formations that indicate the possibility and presence of an oil reservoir. DST, is used primarily on exploratory oil wells and gas wells, to ascertain their commercial productivity
