It operates through the following segments: Hydraulic Fracturing, Cementing, Coil Tubing, Flowback, Surface Drilling, and Drilling. The Hydraulic Fracturing segment intends to optimize hydrocarbon flow paths during the completion phase of horizontal shale wellbores. The Cementing segment provides isolation between fluid zones behind the casing to minimize potential damage to hydrocarbon bearing formations or the integrity of freshwater aquifers, and provides structural integrity for the casing by securing it to the earth. The Coil Tubing segment involves injecting coiled tubing into wells to perform various completion well intervention operations. The Flowback segment consistsof production testing, solids control, hydrostatic testing and torque services. The Surface Drilling segment offers cost-effective, pre-set surface air drilling services to target depths of approximately 4,000 feet in areas of fragile geology.
