Miller Energy Resources Announces $100 Million Credit Facility and the Successful Redevelopment of the RU-1 Well in Alaska

HUNTSVILLE, Tenn., June 13, 2011/PRNewswire/ -- Miller Energy Resources, Inc. (“Miller”) (NYSE:MILL), a high growth oil and natural gas exploration, production and drilling company, announced today that it had closed on a two year, $100 million credit facility with Guggenheim Corporate Funding, LLC, Citi and Bristol Investment Fund, Ltd. Munger, Tolles and Olson, LLP advised Miller on the transaction. The credit facility, which provides for an initial borrowing base of $35 million, is secured by substantially all of the company’s and its subsidiaries’ assets. Proceeds from the loan will be utilized to fund development and the construction of a drilling rig to be used to increase oil production both onshore and offshore in Alaska through the drilling of new wells and the reworking of previously producing oil wells.

Miller has also successfully redeveloped the RU-1 well on the Osprey platform in the Cook Inlet in Alaska by changing an electric submersible pump (“ESP”). The well is currently flowing above expected rates at a steady rate of approximately 350 Bbls/d gross.

Miller is continuing redevelopment operations on the Osprey and is currently replacing the ESP on the RU-7 well, which is expected to come online in the next week. Following this replacement, Miller plans to redevelop and drill additional wells in the Cook Inlet, including the four wells that are expected to produce an additional 2,000 Bbls/d gross from the Osprey platform.

“From both a financial management and operational standpoint, I am very proud of our Company. Today we have announced a $100 million credit facility with major financial institutions and the successful redevelopment of the RU-1 well in Alaska. The credit facility ensures that Miller has the funding to dramatically increase production through low-risk development, which will build significant long-term value for our shareholders.  Obtaining a credit facility without an equity component led by Guggenheim was very important for Miller. Beyond the financial security provided by the facility, Miller is pleased to have access to Guggenheim’s significant financial capabilities and extensive oil and gas expertise. With the successful redevelopment of RU-1, which is exceeding expectations, we continue to demonstrate our operational expertise and our ability to cost effectively operate and redevelop wells in the Redoubt field and our other Alaskan assets.” said Scott M. Boruff, Miller CEO. “The credit facility ensures that Miller has the funding to dramatically increase production through low risk development which will build significant long term value for our shareholders.”
