Participating in the following two wells at an aggregate net cost of US$263,708: Well Name Targeted Formation Operator Magnolia's Net Cost to WI/NRI% Magnolia Jimmy 1-28H Woodford, Oklahoma Red Fork 3.777/3.022 US$139,662 Energy Peters 1-27H Woodford, Oklahoma Paul Gillham 5.208/4.167 US$124,046 Increase in interest in Skunk Creek wells, North Dakota & Estimate of Reserves The Company has increased its interest in the spacing unit in North Dakotawhere the Skunk Creek 14H and Skunk Creek 15H wells are currently producingfrom the Bakken and Three Forks Sanish formations. Magnolia now holds a 0.90%and 0.675% working/net revenue interest (previously 0.60% and 0.45%respectively) in both of the above wells and also the four infill wells thatare to be drilled on the unit in the near term, as detailed in the announcementof 20 January 2014. The operator, Kodiak Energy, has estimated a total of 4.976 million barrels ofoil and 2.88 Bcf of gas can be recovered from the Skunk Creek spacing unit bydrilling eight wells, four each to the Bakken and Three Forks Sanishformations, based on the per well estimate provided in Table 1 below. The totalestimated level of reserves attributable to Magnolia on the Skunk Creek spacingunit is therefore 33,600 barrels of oil and 19.44 MMCF of gas. Rita Whittington, COO of Magnolia, said, "Jimmy and Peters bring the totalnumber of wells in proven US onshore formations in which we have an interest to205, more than three times the number at the time of our Admission to AIM inNovember 2011. We have over 600 potential drilling locations on our leases, andwith the multiple proposals we are receiving to participate in new wells, weexpect to build on the excellent growth seen to date. Meanwhile, on-goingleasing activity allows us to add to the 13,500 net mineral acres we hold,including those leases in which we already have an interest such as SkunkCreek. The operator's estimate of recoverable reserves at Skunk Creekillustrates the prolific nature of the Bakken and Three Forks Sanish formationsand bodes well for our other leases in North Dakota including the Statoiloperated Jake wells. I look forward to providing further updates on ourprogress in due course.
