We offer


   Drill-stem formation tester equipment is designed for hydrodynamic surveys of formations and extracting downhole samples from them in the testing process. They allow testing in the multi-purpose mode in the drilled wells with a diameter from 76 to 295 mm.

   This results in considerable reduction of time spent on search and exploration of new fields due to quick receiving of information about the saturation characteristics of reservoir formations.

   During drill stem testing a much wider radius of production formation survey is ensured thereby solving the task of determining the industrial significance of the reservoir, and, according to the pressure diagram interpretation results, the quantitative characteristics of the downhole formation zone state, productive potential and formation pressure are determined.

   The complex includes: filter, anchor, packer, formation tester, jar, shutoff valve, circulation valve, casing head, instrument branch pipes for installation of self-contained pressure gages – thermometers and other units ensuring survey by the selected technology.
