What is DST (Drill Stem Testing)?

A drill stem test (DST) is a procedure that determines the pressure, permeability and productive capacity of a geological formation while drilling a well. The test is crucial in measuring pressure behavior at the drill stem and is an effective way of obtaining data on the formation fluid, and determining whether a well has found a commercial hydrocarbon reservoir. Drill stem testing can be applied in the following ways: 1. Cased Hole stimulation This testing is done after the well is cased and u

@jamalalmaqbali. DRILL STEM TESTING (SRO) The Drill Stem Test (DST) plays a pivotal role in prospect evaluation and subsequent field development planning. Therefore, it is imperative to acquire reliable, high-accuracy downhole pressure and temperature data in a timely manner in order to allow the reservoir evaluation to be conducted without introducing additional uncertainty or delay. #oilandgasindustry | OilRegistry
