Greenfields Petroleum Corporation: Reserves Release

CALGARY, ALBERTA--(Marketwired - April 30, 2013) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES. ANY FAILURE TO COMPLY WITH THIS RESTRICTION MAY CONSTITUTE A VIOLATION OF U.S. SECURITIES LAWS.

Greenfields Petroleum Corporation (the "Company" or "Greenfields") (TSX VENTURE:GNF) (TSX VENTURE:GNF.DB) announced that it has filed its statement of reserves data, the reports of its independent qualified reserves evaluator and the related report of management and directors (National Instrument 51-101 Forms 51-101F1, 51-101F2 and 51-101F3) for year-end 2012 with the securities regulatory authorities of Canada. More detailed information can be viewed on the Company's SEDAR profile at www.sedar.com.

Total proved reserves are stated at 8,951 MBOE net to the Company through its interest in Bahar Energy Limited (Azerbaijan), a 3% decline from year-end 2011, while total proved plus probable reserves are stated at 12,575 MBOE net to the Company, a 4% increase from year-end 2011. The changes to the proved reserves were principally due to production and the late start of development drilling in 2012.

The present value of future net revenue discounted at 10% ("PV10") of the proved reserves is US$48.67 million net to the Company at year-end 2012 (down 33% from year-end 2011), while the PV10 of the proved plus probable reserves is US$117.7 million at year-end 2012 (down 11.9% compared to year-end 2011). The change in value is primarily associated with changes in future oil pricing assumptions as applied by the independent qualified reserves evaluator. Secondary factors, which collectively have a minor impact on the PV10 value, include the delay to the start-up of development drilling and an increase in drilling and completion costs.

Forward Looking Statements

The forward-looking statements contained in this press release are based on certain key expectations and assumptions made by Greenfields. Although Greenfields believes that the expectations and assumptions on which the forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because Greenfields can give no assurance that they will prove to be correct.

Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties most of which are beyond the control of Greenfields. Should one or more of these risks or uncertainties materialize, or should assumptions underlying the forward-looking information prove incorrect, actual results, performance or achievements could vary materially from those expressed or implied by the forward-looking information. These risks include, but are not limited to, risks associated with the oil and gas industry in general (e.g., operational risks in development, exploration and production; delays or changes in plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses, and health, safety, political and environmental risks), commodity price and exchange rate fluctuations and uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures. Additional risk factors can be found under the heading "Risk Factors" in Greenfields' Annual Information Form and similar headings in Greenfields' Management's Discussion & Analysis which may be viewed on www.sedar.com.

The forward-looking statements contained in this press release are made as of the date hereof and Greenfields undertakes no obligation to update publicly or revise any forward-looking statements or information, whether as a result of new information, future events or otherwise, unless so required by applicable securities laws. The Company's forward-looking information is expressly qualified in its entirety by this cautionary statement.

The term "barrels of oil equivalent" or "boe" may be misleading, particularly if used in isolation. A "boe" conversion ratio of 6 Mcf:1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
