Exhibit 99.1

Tim P Burroughs, President and CEO of Frontier Oilfield Services, Inc (OTCQB: FOSI) announced today that the Company has completed the acquisition of Chico Coffman Tank Trucks, Inc (“Coffman”), including its wholly owned subsidiary, Coffman Disposal, LLC, which had audited gross revenue in 2011 of $40,500,000 and net income before interest, taxes, depreciation and amortization of $3,263,000.

Coffman’s primary services wells owned and operated by Devon Energy (DVN), XTO Energy (XTO), Pioneer Natural Resources (PXD) and EnCana Corporation (ECA).

Tim P Burroughs, President of Frontier Oilfield Services, Inc, stated, “The acquisition of Coffman allows Frontier to expand its operations across North Central and East Texas and was a next step to our business strategy of geographic expansion over the US mid-continent region.”

ABOUT FRONTIER OILFIELD SERVICES, INC

Frontier Oilfield Services, Inc.’s 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 saltwater. 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.
