Magnolia Petroleum COO, Rita Whittington said, "We are delighted to be able to 
provide our shareholders with such a positive update on our operations so close 
to our listing on AIM last month. The successful drilling of the two wells at 
Skunk Creek and reaching total depth in the Stocke well provides us with huge 
encouragement as we continue to participate in drilling in the highly 
productive Bakken/Three Forks Sanish formations. We are particularly excited 
about the Skunk Creek Three Forks Sanish well, as Moyes & Co. our Competent 
Person singled out this well as a trigger for a significant shift in Magnolia's 
reserve categories once the well has been successfully drilled and is 
producing. 
 
"Modern technology such as multi-stage frac techniques used in the completion 
of horizontal wells has increased production tremendously in non-conventional 
oil and gas plays. Magnolia's participation in the Drone well, completed as a 
30 stage frac, yielded an initial production of 1,199 barrels of oil per day, 
and nearly trebled Magnolia's net production interests to approximately 20 
barrels per day. We are extremely pleased with the Company's participation in 
successful drilling programmes to date and our highly experienced Board 
anticipates the Stocke and Skunk Creek wells will prove to be highly productive 
and will add to our outstanding success rate to date. With this in mind, I very 
much look forward to updating shareholders on our progress." 
 
Detailed Information 
 
Reports have now been received from the operator in respect to the Skunk Creek 
Wells, located in Dunn County, North Dakota. Magnolia participated with a 0.59% 
interest in the drilling of each of these two wells with Kodiak Exploration. 
The primary targets for these wells were the Three Forks Sanish and the Bakken 
Formations. Both wells have successfully been drilled and are awaiting 
completion. According to the operator, they are highly encouraged by the shows 
and have applied to the North Dakota Industrial Commission to drill an 
additional three Bakken wells and three Three Forks Sanish wells within the 
same spacing unit. Multi-stage frac techniques between 23 and 24 stages are to 
be performed on these wells. This information is in line with Magnolia's 
Competent Person's Report (announced 25 October 2011 and contained, in full in 
the AIM admission document) which indicates that the Bakken is being infill 
drilled to four wells per 1,280 acres spacing and the Three Forks Sanish is 
also starting to be developed in the area at four wells per 1,280 acre spacing 
unit. This infill drilling would allow for an additional 78 Bakken and 107 
Three Forks Sanish locations for a total of 108 wells in the Bakken and 108 
wells in the Three Forks Sanish. Once permission is obtained and these initial 
six wells are drilled, the Company expects that its overall production 
interests will increase substantially. 
 
In addition, Magnolia participated with Hunt Oil Company in the drilling of the 
Stocke 1-4-9H well, located in McKenzie County, North Dakota. The Stocke well 
reached total depth on 2 December 2011 and is awaiting completion. This well 
will have a 21 stage frac treatment. Magnolia has a 3.17% working interest in 
this well, which is nearly two and a half times larger than Magnolia's 1.34% 
working interest in the Drone well which yielded total initial production of 
1,199 barrels of oil per day (as announced on 4 November 2011). 
 
Completion on the Skunk Creek and Stocke wells described above are expected to 
start by year-end.
