Gasco and Wapiti Close Uinta Basin Joint Venture Transaction

DENVER and HOUSTON — (PR Newswire) — March 26, 2012 — Gasco Energy, Inc. (NYSE Amex: GSX) (“Gasco”) and Wapiti Oil & Gas II, L.L.C. (“Wapiti”) today jointly announced that a Gasco Energy, Inc. subsidiary, Gasco Production Company (“Gasco Production”) and Wapiti closed their previously announced transaction in which Gasco Production (I) sold to Wapiti an undivided 50% interest in certain of its Uinta Basin producing oil and gas assets for an aggregate amount of $19.1 million in cash and other consideration and (II)transferred to Wapiti an undivided 50% interest in its Uinta Basin non-producing oil and gas assets in exchange for, among other agreements, Wapiti’s commitment to fund $30 million of the drilling and completion costs associated with the exploration and development of the transferred assets.

The deal closed on terms substantially similar to those previously announced.  Gasco Production was unable to obtain the required consent to the transaction from one working interest owner and, as a result, Gasco Production retained all of its interests in 34 producing wells currently producing approximately 1.25 million cubic feet equivalent per day, net to Gasco Production’s interest.

“With our new joint venture with Wapiti, Gasco has completed the first step of its strategy of positioning itself to take advantage of opportunities outside of Utah while remaining well-positioned to participate in our proven natural gas play as prices recover,” said King Grant, Gasco’s President and CEO. “We look forward to investing alongside Wapiti in the Uinta drilling program that we expect to commence this summer.  The drilling program is weighted towards the more liquids-rich Wasatch and Mesaverde formations.  We also plan to take advantage of the current strong oil price environment by allocating some of the investment to our Green River oil potential.  In a collaborative effort with Wapiti, we look forward to jointly developing our large Uinta Basin hydrocarbon resource to generate growth in reserves, production and cash flow.”

“This joint venture complements Wapiti’slarge, low-risk Rockies natural gas asset portfolio,” said Bart Agee, Wapiti’s President and CEO.  “I am extremely excited about these assets and in the team that we have put together that will be working on this project.”
