The first exploratory drilling occurred in 1998 in a single drilling campaign when 6 wells were drilled. 5 of the wells had oil and/or gas shows, with one well flowing oil to the surface. The deposits were small and not commercial, and given the low price of oil prevailing then, no further drilling was undertaken. However, various estimates of volumes of oil that lie in the area have been made, with some sources saying about 60 billion barrels lie in the area. These potential huge undiscovered volumes have managed to keep some companies, albeit relatively smaller, interested in the area.
A. Falkland Oil and Gas Ltd: Falkland Oil and Gas Limited (FOGL) is an AIM-listed oil and gas exploration company operating in the South and East Falkland Basins.
E. Borders and Southern Petroleum: Borders & Southern is a UK-based, London Stock Exchange (AIM) listed company. It holds a 100% interest and operatorship in five Production Licences covering an area of nearly 20,000 sq km.

Rockhopper Falkland Islands Exploration
Rockhopper Group has 100% of 4 licences in the North Falkland Basin, PL023, PL024, PL032 and PL033, between them covering an area of ~ 3800 sq. km. The Ernest prospect identified on the blocks was drilled in July 2010. However, the well did not encounter any hydrocarbons and was plugged and abandoned. On April 16, 2010 the Company spudded an exploration well Sea Lion 14/10-B on the Sea Lion prospect in PL032 which encountered oil. After very positive appraisal drilling, plans are currently to test the well, and also drill another appraisal well. As on 14 March 2011, a wider seismic acquisition programme, over areas of licences PL024, PL032 and PL033 and adjacent areas, is ongoing, and the company has secured four firm additional well slots and plans to drill in PL 032 in the near future.
PL 001
Production License 001 is located in the North Falkland Basin, offshore Falkland Islands and occupies an area of about 1,126 sq km. Argos Resources has completed 2D seismic survey over the license and based on the report about seven prospects and five leads have identified. The Company carried out a 1,415 sq kms of 3D seismic data aquisition in 2011 and plans to drill exploration wells in late 2011 or early 2012. Argos holds 100% interest in the licence.

Enter Sea Lion!
Rockhopper, the company that holds exploratory acreage around the Falkland Islands, drilled the Sea Lion discovery well during April and May 2010. The well discovered 53 m of net oil pay in multiple zones of good sands and was flow-tested at over 2300 barrels of oil per day under restricted testing conditions. This was the first proper oil discovery and apart from pushing up Rockhopper’s share price considerably, it also significantly de’risked the area. After very positive appraisal drilling, plans are currently to test the well, and also drill another appraisal well. The 2nd appraisal well (14/10-5) reportedly flowed at commercially viable rates. Further appraisal drilling is being progressed over the coming months to continue to define the extent of the Sea Lion resource. It is highly likely that this discovery will be commercial, and if so will herald a new chapter in the Islas Malvinas history.

FOGL - Falkland Islands Northern Licences
Falkland Oil and Gas Ltd. (FOGL) holds interests in 7 exploration and production licences in the northern region (collectively called Northern Licences) and is the designated operator. The production licences cover ~ 50,000 sq km and are located in water depths ranging from approximately 200 m to 2,000 m. The licences contain many prospects which include the Loligo, Nimrod, Hersilia and Endeavour prospects. The Lologo prospect is scheduled to be drilled in Q1 2012, and possibly other prospects will be drilled depending on FOGL's ability to farm out and acquire funding.

Liz Prospect
The Liz prospect lies in 350m of water offshore Falkland Islands in Tranche C. An exploration well was spudded on the prospect on February 22, 2010. The well encountered 17 metres of net hydrocarbon pay were encountered between 2961 and 3031 metres within a zone of over-pressured, predominantly sandstone, reservoir. The primary and secondary targets had hydrocarbon shows but reservoir quality in both was poor and was in complex stratigraphic traps. As on Feb 2011, the company is reprocessing 3D seismic over the Liz prospect and also plans to shoot more 3D around the prospect to define volumetrics. Desire Petroleum (92.5%) is operator and Rockhopper Exploration (7.5%) is partner.

Ann
The Ann prospect lies in PL 003 Tranche C Ann sub-area in 400m of water. The consortium was planning to spud a well in 2010. However, pending further announcements, it is unlikely this prospect will be drilled in 2011. Desire Petroleum (57.5) is the operator and the partners are Rockhopper Exploration (7.5%) and Arcadia Petroleum (35%).
