How a Drill Stem Test Is Run YouTube
Drill stem test (DST) is the conventional method of formation testing and reservoir evaluation which obtains reservoir data under dynamic (rather than static) conditions. A DST is essentially a temporary completion, a method of evaluating reservoir formations without costly and time-consuming completion procedures.

1. n. [Drilling] A procedure to determine the productive capacity, pressure, permeability or extent (or a combination of these) of a hydrocarbon reservoir. While several different proprietary hardware sets are available to accomplish this, the common idea is to isolate the zone of interest with temporary packers.
Drill Stem Test DST YouTube
A drill stem test ( DST) is a temporary completion of a wellbore that provides information on whether or not to complete the well. The zone in question is sealed off from the rest of the wellbore by packers, and the formations' pressure and fluids are measured. Data obtained from a DST include the following: fluid samples reservoir pressure ( P *)

Introduction A drill-stem test is a temporary completion of the well. Drill-stem tests are usually made for one or both of the following reasons:to determine the producible fluid content of a formation, and to determine the ability of a formation to produce.
Downhole Reservoir Testing Northstar DST Downhole Specialists
drill-stem test . A procedure for determining the potential productivity of an oil or gas reservoir by measuring reservoir pressures and flow capacities while the drill pipe is still in the hole, the well is still full of drilling mud, and usually the well is uncased.

The RezConnect ยฎ well testing system is the industry's first fully acoustically actuated drill stem test (DST) system offering a complete well testing solution for acoustic controls of DST tools with real-time measurements and analysis. The system features a variety of products that measure pressure, fluid samples, and more. Related Products
Drill Stem Testing
A drill stem test (DST) is a method of formation evaluation. The test allows fluids in the formation being evaluated to flow into the drill stem and to the surface. Pressure-recording devices in the drill stem test tool measure and record pressure in the well while it is both flowing and not flowing (shut in).

A drill-stem test, or DST, is the most common method to measure reservoir pressure. DSTs are the most reliable reservoir pressure measurement method if sufficient time elapses during the test for the higher formation pressure to equilibrate with the lower borehole pressure. Pressures often must be extrapolated.

12.1 Introduction. Drill-stem testing provides a method of temporarily completing a well to determine the productive characteristics of a specific zone. As originally conceived, a drill-stem test provided primarily an indication of formation content. The pressure chart was available, but served mainly to evaluate tool operation.

A drill stem test (DST) is a procedure for isolating and testing the pressure, permeability and productive capacity of a geological formation during the drilling of a well.The test is an important measurement of pressure behaviour at the drill stem and is a valuable way of obtaining information on the formation fluid and establishing whether a well has found a commercial hydrocarbon reservoir.
Drill Stem Testing
A Flow test is an operation on a well designed to demonstrate the existence of moveable petroleum in a reservoir by establishing flow to the surface and/or to provide an indication of the potential productivity of that reservoir. Some flow tests, such as drill stem tests (DSTs), are performed in the open hole.

A drill stem test (DST) offers the fastest and safest method of evaluating the potential of a newly-discovered hydrocarbon-bearing formation. After the well has been drilled and cased, the first stage of a well test is to run a DST string in conjunction with a downhole data system with the option to include tubing conveyed sampling
