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), an independent exploration and production company with assets in Azerbaijan, announces that it has confirmed 422 feet and 193 feet of behind-pipe pay thickness based on cased hole production logs in the first two of its thirty-six planned recompletions in the Gum Deniz oil field. Greenfields participates in the Bahar Exploration, Rehabilitation, Development and Production Sharing Agreement through its 33.33%-owned joint venture, Bahar Energy Limited ("BE"), and BE's operating subsidiary, Bahar Energy Operating Company Limited ("BEOC").

Cased hole logging (PNN & Carbon/Oxygen) has been completed on wells #464 and #449. In well #464, four zones (X, IX, VIII and VI) have been confirmed to have approximately 422 feet of behind-pipe pay thickness from the cased hole logging program. In well #449, three zones (IX, VIII and VI) have been confirmed to have approximately 193 feet of behind-pipe pay from the cased hole logging program.

During the next thirty days, completion activities will be underway to test the various zones in each well. In well #464, completion of zones X and IX are set to be tested together and then later evaluations of zones VIII and VI will be made. In well #449, Zone IX will be the only zone to be completed. BE intends to evaluate zones VIII and VI at a later date.

As previously announced, BEOC has contracted two new western-style workover rigs, the first to arrive before year-end and the second in early 2012. After these two rigs arrive, Greenfields intends to proceed with twenty-four recompletions in the subsequent twelve-month period in the Gum Deniz oil field and the Bahar gas field.
