Eco-Stim Energy Solutions Broadens Its Customer Base With Strong Operational Performance

HOUSTON and NEUQUEN CITY, Argentina, March 2, 2015 (GLOBE NEWSWIRE) -- Eco-Stim Energy Solutions, Inc. (OTC: ESES) ("EcoStim" or the "Company") announced today that the Company has now qualified and successfully conducted its first well stimulation job for the largest exploration and production company in Argentina after previously completing work for several other operators in the Neuquén province, home of the Vaca Muerta shale formation. The qualification and successful operation for this customer is a major accomplishment considering that Eco-Stim only recently started its operation in Argentina. Eco-Stim is now an approved "on-call" vendor and is currently in discussion with this customer to dedicate a portion of its equipment capacity for several additional jobs to be executed in the months ahead.

Bobby Chapman, the Company's Chief Operations Officer, stated, "This is a very significant milestone for our Company. This operator has a substantial exploration, development and production budget and with no planned reductions in capital spending during 2015 as compared to 2014. To obtain technical and commercial approval from this customer and successfully complete a job only two months after starting our first operation is a major success for the Eco-Stim team. We believe Argentina will continue its push for energy independence and as a result, the government will continue to embrace policies and commodity prices that allow the local exploration and production companies to economically produce both oil and natural gas. As activity in the country continues to accelerate, we anticipate many opportunities will arise to provide quality service and innovative technology."

Hector Sanchez, Operations Manager for Eco-Stim Energy Solutions Argentina ("Eco-Stim Argentina"), stated, "We are very excited about the credibility our team has generated with this operator. We see many growth opportunities in the region and remain very excited about the future. Our entire team once again did a great job and we look forward to continuing this relationship and conducting many more jobs for this important customer."

Jorge Robles, Director of Sales for Eco-Stim Argentina, commented, "I want to congratulate our operations and technical teams for making my job easy. When you can bring your customers quality equipment complemented with a safe, well-trained crew, most customers are going to be happy. With this customer expressing a desire to utilize our crew on a more regular basis, I would say that our available capacity is starting to be strained. I look forward to getting our second well stimulation fleet in operation later this year."
