Drillstem Testing

A Drilling Stem Test (DST) is a pivotal procedure in the oil and gas industry, conducted during the drilling of a well. It involves the deployment of specialized downhole tools, including a packer and control valve, to isolate and evaluate a specific geological formation’s reservoir properties. By monitoring pressure, flow rates, and fluid composition, DSTs provide crucial insights into the formation’s potential productivity, permeability, and fluid properties. This data guides decisions on well completion, reservoir viability, and production strategies, ultimately playing a vital role in optimizing the economic success of oil and gas wells.
