Earthstone Energy Furnishes 2nd Quarter Operations Update

November 8, 2013

DENVER, CO--(Marketwired - Nov 8, 2013) - EARTHSTONE ENERGY, INC. ( NYSE MKT : ESTE ) furnished an update of its current operational activities along with activities for its 2nd fiscal quarter, ended September 30, 2013. 

Operations Update
Banks Field, McKenzie County, North Dakota
There continues to be excellent potential for reserve growth in the Banks area, where we placed seven new wells on production in the second quarter, ended September 30, 2013. All seven wells are operated by Statoil and include, the Enderud 9-4 4TFH, Beaux 18-19 2TFH, Beaux 18-19 7H, Sax 25-36 3H, Sax 25-36 4TFH, Sax 25-36 5H and Sax 25-36 6TFH. Currently, two wells are drilling and six wells are being completed or are waiting on hydraulic stimulation. 

With respect to oil and gas reserves classifications, at quarter-end, five wells were reclassified from Proved Undeveloped (PUD) to the Proved Developed, Producing (PDP) category and seven wells were reclassified from Proved Developed, Non-Producing (PDNP) to PDP. In addition, four wells were reclassified from PUD to PDNP. 

Nebraska Deep Prospect, Cheyenne County, Nebraska
The Company resumed completion operations on the Schmale 34-20 in mid-October. During completion operations, one additional zone was tested in a Permian age interval. Similar to the two previous tests, some oil was recovered, but volumes were not sufficient to warrant building production facilities. The Company and its partners have suspended operations and are assessing further actions. This decision will most likely be to plug and abandon the well, but could include further stimulation to existing zones or testing additional zones. Earthstone is the Operator of the well and has a 45% working interest in this venture. The remaining ownership in this project is held by unrelated, privately-held, third parties.

South Texas Legacy Waterfloods, Webb County, Texas
The Company continues to geologically re-evaluate our long-held, waterflood properties in south Texas. Currently, these fields generate 10% to 15% of our cash flow and wells in this field are shallow and inexpensive to drill. Based on the preliminary results of this re-evaluation, the Company anticipates a modest drilling program will be undertaken this winter or spring.
