Wellhead Isolation and Frac Stacks
Utilizing a significant catalog of intellectual property and a highly experienced work force, our Stinger Wellhead Protection, Schooner Petroleum Services and STS subsidiaries provide wellhead protection equipment utilized during the pressure pumping process. Stinger is the leading provider of isolation tool services in North America and internationally. Through its proprietary wellhead isolation tools, Stinger allows pressure pumping companies to operate in a safe manner and protects an operator's production wellhead from the effects of pressure and abrasion that occur in the frac process. Schooner and STS provide frac stack rental that temporarily replace the production wellhead during the pressure pumping process and allow high pressures and high volumes of proppant to pass down to the formation.

Flow Back and Well Testing
After the frac process is complete, an operator needs to remove the sand and other material from the formation and test the quality of the well production. These processes are known as flow back and well testing. Our Well Testing Inc. and Schooner subsidiaries provide these services to a variety of customers throughout some of the most active regions in the U.S. Well Testing utilizes a high quality fleet of manifolds, sand separators and testing units as well as a highly experienced work force to provide customers with timely and accurate measurements. Schooner, using its proprietary sand separator technology, provides flow back services through 11 locations in the U.S.
