Eco-Stim Energy Solutions Signs Second Contract To Expand Operations in Oklahoma -- Dedicated Crew For New Customer

HOUSTON, TX and NEUQUEN CITY, ARGENTINA--(Marketwired - Jul 20, 2017) - Eco-Stim Energy Solutions, Inc. (NASDAQ: ESES) ("EcoStim" or the "Company") announced today that the Company has executed a one-year agreement with a US oil and gas exploration and production company to expand its pressure pumping operations in the north central region of Oklahoma. The Company expects that the work to be performed under this contract should support a second well stimulation crew allowing the company to further expand its footprint in this region. The contract has an option, exercisable by the Company's customer, for a second year.

While the contract does not require the customer to award any specific volume of work to the Company, the contract provides ESES with the exclusive right to complete all of the customer's wells so long as ESES meets the operational standards required. Currently, the customer expects to complete 2-3 wells per month and is operating two drilling rigs in this region. Each well is expected to be completed with approximately 25 stages and will require approximately 40,000 HHP.

J. Chris Boswell, EcoStim's President and Chief Executive Officer, commented, "After starting our U.S. based operations in late May 2017, we have been in discussions with several other operators working in the Scoop/Stack Merge plays and these discussions have now led to the signing of a commercial contract. We believe that this agreement will be a foundational contract that should enable the Company to participate in the expanding activity levels indicated by the recent rig count increase within the Scoop/Stack/Merge formations being developed in the region. We continue to believe that this area is poised for growth and this contract will position the Company with a second significant customer in the area."
