The Drill Stem Tests will definitely add value to our project in regard to gaining information on whether the formations above and below the area of interest are fluid bearing or not. This information will be key in determining cavern design if the project advances past exploration.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.

It is placed in the upper section of the DST tool above the hydraulic by-pass valve. According to (Black, 1956), one of its main functions is to provide a passage for the fluids to flow into the drill pipe when the packer is set at the annulus.

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 samplingA 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.

These devices are known as packers and are used to make a seal between the borehole wall and the drill pipe, isolating the region of interest. A valve is opened, reducing the pressure in the drill stem ...Introduction Drill-stem testing (DST) is one of the most important completion techniques. It is a type of temporary completion that is used to evaluate the formation and inspect a reservoir's properties. According to (Ammann, 1960), the measurement of the reservoir properties by the DST can be delivered directly or indirectly.When drilling deep boreholes in hard rock, the amount of time spent tripping drilling and testing equipment in and out of the borehole (e.g., to change the drill bit, retrieve core samples, conduct a drill-stem test, or perform hydrofracture tests) can be a significant portion of the total time.Drill Stem Test Results from Namibia's Venus-1X Well Positive" alt="Argeo and Shearwater Form Alliance to Transform Subsea and OBN Seismic Markets"> Argeo and Shearwater Form Alliance to Transform Subsea and OBN Seismic Markets " alt="Qatarenergy Signs LNG Ship-Building Agreement with HD Hyundai Heavy Industries"> ...
