Drillstem Testing Services

Determine the commercial viability of your well

Our service guides the next phase for exploration-well drilling and production. Even in extreme or unknown downhole conditions—including sour and HPHT environments—we create a secure temporary completion string that safely flows reservoir fluids to the surface.

Using data from durable quartz gauges, our technicians then deliver a complete reservoir analysis, including identifying boundaries, fluid type, permeability, porosity, skin factor, and flowing and static reservoir pressures and temperatures. We then help you determine whether commercially viable quantities of hydrocarbons exist and, if so, guide decisions on well-completion and production-facility design.
