Rockhopper Exploration Joins Fellow Falklands Explorers On AIM
Investors looking for exposure to wildcats in the southern Atlantic are spoilt for choice with the arrival on Londons Alternative Investment Market of Rockhopper Exploration. The start-up, which has raised 15 million before expenses, joins fellow AIM-quoted Falkland Island explorers Desire Petroleum, Borders & Southern Petroleum, Falklands Oil & Gas Limited (FOGL) and Global Petroleum (which owns 14 per cent of FOGL). This is an area that offers investors a white knuckle ride but this kind of high risk prospecting also offers the potential of major rewards.
Rockhopper, which started trading in February 2004, owns 100 per cent of four offshore licences, covering 5,800 sq km of the North Falkland Basin. It also has a farm-in agreement with Desire, giving it the right to earn up to 15 per cent in two further licences (another 1,300 sq km tranche of acreage) by funding up to 30 per cent of the costs of a three-well drilling programme planned for 2006.
The funds raised from the IPO will be used to pay for a 640 sq km 2D survey and 685 sq km 3D seismic over its four 100 per cent owned and operated licences (PL023, 24, 32 and 33) plus the farm-in drilling costs on the Desire acreage.
Despite the remote location - the islands lie 300 miles east of Argentina - this is not virgin territory. The North Falkland Basin was home to a much-hyped drilling programme in 1998, when four consortia shared a rig to drill six wells. The well results failed to match expectations but, equally, in no way wrote off the prospectivity of the region. Rockhopper, which is named after the penguin colonies on the Falklands, holds the ex-Shell acreage. Shell drilled two wells: one flowed gas to the surface, the other encountered live oil.
Of the six wells, only one was completely dry and five found non-commercial quantities of oil and gas, Rockhoppers managing director Sam Moody told oilbarrel.com. The North Falkland Basin stretches 250 km from north to south and there have only been six wells and they all tested the same type of play concept. If you look at the North Sea, there were a lot of wells drilled before they found a commercial oil discovery.
The next phase of exploration in the North Falkland Basin will target a different play concept, Moody explained. The first six wells proved the existence of a world class source rock, the lacustrine, estimated by the British Geological Society to be the second richest source rock in the world. It is thought this source rock could have generated 100 billion barrels of oil much of which the BGS reckons is trapped beneath the uppermost part of the lancustrine interval, which may have forced the oil to migrate toward the basin margins or into sands older than the source rock.
None of the wells drilled to date have targeted sands within or beneath this source rock, nor have they tested the margins of the basin. Rockhopper believes these targets represent a major untested oil play.
It is keen to prove its concept. The company is currently designing the parameters of its seismic programme and talking to seismic contractors about boat availability. Desire, meanwhile, is preparing for next years drilling programme and is in touch with drilling contractors about rig availability (water depths here are under 500 metres allowing for the use of standard semi-submersible kit). Preparations are underway for the drilling programme, buying in consumables and getting Health & Safety up to speed, so that as soon as a rig becomes available at the right price the partners can get to work.
There has already been a spurt of activity in the waters to the south and east of the Falkland Islands, an area geologically distinct from the North Falkland Basin. Borders and Southern Petroleum recently completed a 2,860 km 2D shoot over its 19,598 sq km tranche of acreage while FOGL has a busy 2D and 3D schedule underway.
FOGLs acreage covers 83,700 sq km, equivalent to the North Seas Southern Gas Basin and Central Graben, and the company has already identified 130 leads distributed across different play types, some of which could hold recoverable reserves in excess of 200 million barrels. The 2D survey has identified numerous Direct Hydrocarbon Indicators, seismic signals that point to the presence of working petroleum systems. Some of these DHI leads cover areas of 300 to 500 sq km. First drilling here is slated for 2007.
Exploration success by any of these companies, whether north or south of the islands, will be good news for their fellow Falklands explorers and put this region firmly on the oil and gas map.
