Stimulation Services. Our fluid-based stimulation services include fracturing and acidizing, which are designed to improve the flow of oil and natural gas from producing zones. Fracturing involves pumping a fluid mixture, often a combination of water, sand and chemicals, at a sufficient pressure to create a fracture in a chosen formation that becomes a pathway for hydrocarbons to flow into the wellbore and increase the wells productivity. Acidizing entails pumping large volumes of specially formulated acids into a carbonate formation to dissolve limestone and other materials that block the reservoir and eliminate obstacles to the flow of oil and natural gas. Our fluid technology expertise and specialized equipment have enabled us to provide stimulation services with relatively high pressures (8,000 to 10,000 pounds per square inch, or psi) that many of our smaller independent competitors currently do not offer. We currently have 16 stimulation crews of approximately six to 20 employees each and a fleet of 166 vehicles, including 70 high-tech, customized pump trucks, blenders and fracturing stimulation vans, or frac vans, for use in our fluid-based stimulation services
