Calgary, Alberta, March 3, 2014 - Calvalley Petroleum Inc., (TSX: CVI.A) provides 2013 reserves update.

Calvalley Petroleum Inc. ("Calvalley" or the "Company") announces the results of its December 31, 2013 reserves evaluation.

The reserve evaluation was conducted by McDaniel & Associates Consultants Ltd. who prepared an independent engineering evaluation of the reserves attributable to the Company's 50% working interest in Block 9 in a report dated February 26, 2013 with an effective date of December 31, 2013 (the "McDaniel Report") in accordance with National Instrument 51 101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101") and the Canadian Oil and Gas Evaluation Handbook ("COGE Handbook").

Drilling activity in 2013 included the drilling of four new prospects, Ras Nowmah South, Ras Nowmah North, Sueda and Al Hedba plateau. Ras Nowmah South was completed and put on production during the year. The level of drilling activity was restricted by security and local issues during 2013.

The following information is derived from the McDaniel Report.

Company interest proved reserves of crude oil of 11.5 million barrels declined from 12.5 million barrels in 2012. Similarly company interest proved plus probable reserves of crude oil of 22.9 million barrels declined from 25.2 million barrels in 2012.

Notes:

(1) "Proved" reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

(2) "Probable" reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves.

(3) "Possible" reserves are those additional reserves that are less certain to be recovered than probable reserves. There is a ten per cent probability that the quantities actually recovered will equal or exceed the sum of proved plus probable plus possible reserves. It is unlikely that the actual

remaining quantities recovered will exceed the sum of the estimated proved plus probable plus possible reserves.
