Magnolia Petroleum Plc, the AIM quoted US onshore focused oil and gas exploration and production company, is pleased to announce an update on its activities across its portfolio of interests in proven oil plays including the Bakken/Three Forks Sanish, North Dakota and the Mississippi Lime and Woodford/ Hunton formations in Oklahoma, in line with its expansion strategy to rapidly grow production and revenues.

Overview:

* Prucha 1-23MH well, operated by Devon Energy, targeting the Mississippi Lime has now completed and initial production rates awaited - 25% working interest and 18.75% net revenue interest * Commencement of production at Henry 2-29 vertical well in the Wilcox formation, Oklahoma - 2.4373% working interest and 1.828% net revenue interest * + Gross initial production rate of 35 bopd - in line with expectations + Expected payout (recovery of costs) of less than 12 months, ahead of the current portfolio average + Based on success of Henry well, Magnolia is participating in two direct offsets (Bowen 2-29 and Bowen 3-29) * Participation in Phenom 1-14H well in Mississippi Lime Formation, Oklahoma (operated by Territory Resources LLC) with a net revenue interest of 1.72626%

Magnolia COO, Rita Whittington said, "Our participation in the Phenom and two Bowen wells brings the total in which we have an interest in to 100 (82 producing, 9 drilling, 9 waiting to spud). The speed with which we have reached this milestone is testament to the accelerating activity and interest in the proven oil formations in which we are active, including the prolific Bakken/ Three Forks Sanish, North Dakota and the Mississippi Lime and Woodford/Hunton, Oklahoma.

"Increasing the number of wells in which we participate along with the average size of our interests are the key drivers behind our successful strategy to grow Magnolia's revenues substantially. Furthermore, with 9 wells currently drilling/ completing and 9 waiting to spud, we are on track for our target of interests in 100 producing wells by the end of the year, and shows we are delivering on our objective to rapidly grow revenues and, in the process, build a significant oil and gas company."

Further Information:

Initial Production from Henry 2-29(`Henry well')

Basis (`Basis'), the operator of the Henry well, has reported an initial production rate of 35 bopd, which is in line with management's expectations. Henry 2-29 is a vertical well targeting the historically producing Wilcox formation in Oklahoma in which Magnolia has a 2.4373% working interest and a net revenue interest of 1.828%. As a result, out of a total cost of US$558,500, the Company's share is US$13,612. Based on the initial production rates, the well is expected to payout (recover its costs) in approximately under 12 months.

Following the success of the Henry well, Magnolia is participating with Basis in two additional direct offsets to the Henry, the Bowen 2-29 and Bowen 3-29, to optimise the recovery of all the reserves. As with the Henry well, Magnolia has a 2.4373% working interest in each Bowen well, resulting in its estimated share of drilling costs of US$13,612 each.

Participation in the Phenom 1-14H(`Phenomwell')

Magnolia has also elected to participate in the Phenom well, a horizontal well to test the Mississippi Lime Formation, Oklahoma. Magnolia holds a 2.1484% working interest and a 1.72606% net revenue interest in the Phenom well which is operated by Territory Resources LLC. The total estimated cost for the proposed work is US$3,040,550 with the Company's share estimated at US$65,323.18.
