Miller Energy Resources Announces Updated Reserve Report

Proved Developed Reserves PV-10 Increased From $32.8 Million to $297.8 Million; Expected to Increase to Over $350 Million Following Acquisition of North Fork

ANCHORAGE, AK--(Marketwired - Dec 12, 2013) - Miller Energy Resources Inc. (the "Company" or "Miller") (NYSE: MILL) announced a substantial increase in the value of its reserves located in the Cook Inlet area of Alaska based on a report issued by Ryder Scott Company (RSC), an independent petroleum reserves engineering consulting firm.

Compared to the value of the Cook Inlet area reserves at April 30, 2013, the December 1, 2013 reserve report shows, approximately, the following:

The majority of the increase to the existing asset base is attributable to the success of the Sword-1 well, with recoverable reserves of 898 Mbbls and a PV-10 value of $63.4 million, RU-2A, with recoverable reserves of 1.5 MMbbls and a PV-10 value of $78.0 million, RU-1A with recoverable reserves of 1.0 MMbbls and a PV-10 value of $52.0 million, and RU-5A, with recoverable reserves of 516 Mbbls and a PV-10 value of $25.1 million.

"We started our process with Ryder Scott in order to facilitate our financing objectives. Given lender focus on proved developed reserves, we expect this report will greatly enhance our ability to access cheaper capital," said Scott M. Boruff, Miller's CEO. "Moreover, the increase in proved developed reserves attributed by Ryder Scott validates our team's ability to execute on our development and acquisition strategy. As we move forward with our planned drilling schedule, we believe this rate of growth will continue in the second half of our fiscal year. While certainly exciting, it is just an early indication of the considerable potential yet to be unlocked at Miller Energy."

The reserve reports were based on SEC pricing. Pro forma reserves combine Miller Energy reserves as of December 1, 2013 and North Fork reserves as of December 1, 2013. Actual North Fork acquisition reserves are effective as of the closing date for the acquisition and will not include production from the North Fork Unit between December 1, 2013 and the actual closing date.

The reserves quoted in this release were estimated based on the definitions and disclosures guidelines contained in the Society of Petroleum Engineers, World Petroleum Council, American Association of Petroleum Geologists and Society of Petroleum Evaluation Engineers Petroleum Resources Management Systems.
