The drill stem testing (DST) bottomhole assembly is designed around your test objectives and well parameters. Our focus is providing downhole systems, including perforating guns, with the functionality to effectively and safely perform the well test, while capturing quality data, such as bottom-hole pressures and temperatures during flow (drawdown) and shut-in (build up) periods and representative single-phase formation fluid samples.

  • Over 30 years of DST heritage
  • More than 2,000 successfully completed DST jobs
  • In more than 25 countries
