Magnolia Petroleum Plc / Index: AIM / Epic: MAGP / Sector: Oil & Gas 25 July 2013 Magnolia Petroleum Plc (Magnolia or the Company) Excellent Initial Production at Second of Six Jake Wells in North Dakota Magnolia Petroleum Plc, the AIM quoted US onshore focused oil and gas exploration and production company, is pleased to report an initial production rate of 2,244 boepd for the Statoil operated Jake 2-11 2TFH well in the Three Forks Sanish Formation, North Dakota, in which Magnolia holds a 1.465% net revenue interest.

This adds 33 boepd to the Companys net production and follows the initial production rates for the Jake 2-11 # 1H, announced on 22 July 2013, which added a further 57.5 boepd net to Magnolia.

This update is in line with the Companys strategy to rapidly build production and reserves on its leases in proven US onshore formations.

Rita Whittington, COO of Magnolia, said, "As a result of this second Statoil operated Jake well, the last four wells in which we have participated in North Dakotas prolific Bakken and Three Forks Sanish formations have added almost 200 boepd net to Magnolia.

Even after taking decline rates into account, this substantial increase in net production will result in a major uplift in revenues which in turn will fund new wells and leases. "Revenues generated from 121 producing wells are funding an ever-increasing proportion of our drilling activity across our portfolio of 13,500 net mineral acres in proven US onshore formations.

With an additional four Jake wells to come, along with other wells in which we have larger working interests such as the Blaser (12.5% working interest), we are highly confident this trend is set to continue." ** ENDS ** Glossary boe means barrels of oil equivalent: a unit of energy based on the approximate energy released by burning one barrel (42 US gallons or 158.9873 litres) of crude oil. There are 42 gallons (approximately 159 litres) in one barrel of oil, which will contain approximately 5.8 million British Thermal Units (MBtus) or 1,700 kilowatt hours (kWh).

The value is necessarily approximate as various grades of oil have slightly different heating values.

BOE is used by oil and gas companies in their financial statements as a way of combining oil and natural gas reserves and production into a single measure. boepd means barrels of oil equivalent per day IPR means initial production rates NRI means net revenue interest WI means working interest For further information on Magnolia Petroleum Plc visit www.magnoliapetroleum.com or contact the following: Steven Snead Magnolia Petroleum Plc +01 918 449 8750 Rita Whittington Magnolia Petroleum Plc +01 918 449 8750 Jo Turner / James Caithie Cairn Financial Advisers LLP +44 20 7148 7900 John Howes / Alice Lane / Luke Cairns Northland Capital Partners Limited +44 20 7796 8800 Lottie Brocklehurst St Brides Media and Finance Ltd +44 20 7236 1177 Frank Buhagiar St Brides Media and Finance Ltd +44 20 7236 1177 Notes Magnolia Petroleum Plc is an AIM quoted, US focused, oil and gas exploration and production company.
