Earthstone Energy Provides Operations Update at Annual Shareholder Meeting

DENVER, CO--(Marketwire - Sep 27, 2012) - EARTHSTONE ENERGY, INC. ( NYSE MKT : ESTE ), at its Annual Shareholder Meeting, reported that since April 1st, the beginning of its fiscal year, it has participated in the drilling and/or completion of twenty-nine horizontal wells in the Williston Basin of North Dakota and Montana. The vast majority of these wells are in the Banks Field and are operated by Statoil, formerly Brigham Oil & Gas, L.P. The working interest in these wells range from 1.4% to 5.8% with an average of 4.2%. Earthstone further disclosed that it has a working interest in twenty-one 1280 acre spacing units in the Banks Field and expects each spacing unit to eventually be developed with four horizontal Bakken and two horizontal Three Forks wells; for a total of six wells per spacing unit.

"What a frenzy of drilling activity we have seen in the last six months," commented Ray Singleton, President of Earthstone. "This has certainly been a busy six months. It is exciting to believe that eventually we may have an interest in over 120 horizontal Bakken and Three Forks wells. Indeed, we expect this year's capital deployment to easily exceed last year's record level of expenditures. Certainly, the timing of drilling operations and capital deployment is at the discretion of the respective operators, and we are not in control of these activities nor of when production may commence. Despite this, we anticipate a positive impact on our production volumes and revenues. As we continue to execute on our growth plan, we have a high sense of confidence these investments will have a positive effect on Earthstone's share price and our shareholder's outlook."
