About Frontier Oilfield Services

Frontier Oilfield Services, Inc.’s (OTCQB:FOSI) primary business focus on wastewater recovery and disposal has been selected due to the recurring nature of the revenues, the relatively high margins and the strong barriers to entry by potential competitors because of the limited supply of state permitted commercial disposal wells. In addition, as a result of breakthroughs in recent technology (the process by which shale oil and gas is extracted), exploration & production companies are faced with increasing volumes of, and thus challenges with regard to the disposal of produced fluids and salt water. Frontier’s acquisition strategy in this highly fragmented, decentralized and essential sector of the energy services market, positions Frontier for potentially rapid expansion and substantial growth in the future.
