31. | MAGNOLIA PETROLEUM PLC | MAY 2012 31 Appendix: Extracts from Competent Person’s Report “A well diversified portfolio of producing properties that provide a stable long life cash flow to underpin the company. It has a small, but well positioned presence in two of the most active unconventional resource plays in North America.” “A state study evaluating oil reserves in the Three Forks Formation in western North Dakota concluded that there could be as much as 2 billion barrels of recoverable oil… based on more than 200 well measurement logs and 85 sets of testimony from technical experts.” “The development of the horizontal drilling technology and the multistage fracture stimulation… have transformed once known, but marginal plays into highly profitable plays.” “The North Dakota leasehold position has the potential… to double the expected recovery of hydrocarbons from the existing asset base providing significant upside to Magnolia.”
