Initial Production Rates

Commencement of production at the Basis operated Bowen 2-29 and Bowen 3-29
vertical wells in the Wilcox formation, Oklahoma

  * Bowen 2-29 - Gross initial production rate above expectations at 65 boepd
    (1.13 boepd net)
      * Bowen 3-29 - Gross initial production rate above expectations at 30 boepd
    (0.52 boepd net)
      * Both wells expected to payout (recover costs) in less than 12 months

The Bowen wells are two additional direct offsets to the Henry 2-29 vertical
well that is producing from the historic Wilcox formation in Oklahoma.
Following the success of the Henry well, the two Bowen wells were drilled to
optimise the recovery of all the reserves. As with the Henry well, Magnolia has
a 2.4373% WI and a NRI of 1.736006% in each Bowen well, resulting in its share
of drilling costs of US$13,612 each. Based on the initial production rates, it
is estimated the Bowen wells will both payout (recover costs) in less than 12
The gross initial production rate for the Paul Gillham & Co operated SPS 6-26
vertical well in the Hunton formation in Oklahoma came in above expectations at
108 boepd (0.678 boepd net). As a result, the SPS well has achieved payout in
less than five months. Magnolia's WI/NRI in the well are 0.8333% and 0.62799%

Existing Well Update 
Magnolia COO, Rita Whittington said, "The initial production rates reported for
the two vertical Bowen wells, combined with the quick payout achieved by the
SPS vertical well provide ready-made examples of the attractive economics
behind drilling the proven reservoirs in Oklahoma. Magnolia's interests in the
Bakken, Three Forks Sanish, Mississippi Lime and Hunton formations continue to
provide attractive opportunities, as demonstrated by the participation in six
new wells mentioned today."

`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
