Rockhopper Exploration Gains On News Of Casper Discovery And Potential Upgrade To Sea Lion Shares in Rockhopper Exploration gained 10 per cent in morning trading to stand at 23.25 pence yesterday after the AIM-quoted explorer announced its second discovery in the North Falkland Basin. Although the first discovery, Sea Lion with a low case oil-in-place estimate of 844 million barrels, is a candidate for a stand-alone development, investors will be reassured that these remote waters in the South Atlantic have the capacity to yield further finds, thereby enhancing the economics of any development and making it more material to potential industry partners
The second discovery was made by the 14/10-9 exploration well, which penetrated multiple targets: Casper (an oil and gas discovery), the Sea Lion (a successful appraisal well) and Kermit (water wet). The Caspar prospect yielded 18 metres of total net hydrocarbon pay (9.6 metres of oil, 8.4 metres of gas) in a good quality reservoir with average porosity and permeability. Rockhopper believes the gas cap would enhance oil productivity from Casper; this could also be a good location for a potential gas disposal well in any Sea Lion development.
This is good news for the AIM-quoted company as the previous well, 14/10-8, was also drilled to target the Casper, Sea Lion and Kermit prospects but found all three to be water wet. Rockhopper reckons that well, drilled last month, penetrated a relatively restricted area of the Sea Lion Main Complex which appears to be separated from the rest of the field by a fault.
The 14/10-9 location, however, delivered good news from Casper and Sea Lion although Kermit was again water wet. The Sea Lion appraisal was very positive with chief executive Sam Moody believing it will significantly increase the minimum case area for the field, moving it up towards the previously mapped mid-case scenario. Management estimates previously put the low case at 844 million barrels of oil in place, with a medium case of 1.3 billion barrels and a high case of 1.4 billion barrels.
Rockhopper, which holds the acreage on a 100 per cent basis, has already started mulling development options. It has worked up a development plan on the basis of a recoverable resource of 350 million barrels using a leased FPSO. This wont be cheap development costs to first oil are put at US$2 billion with the company targeting first oil in early 2016, ramping up to output of 120,000 bpd by 2018. The company plans to get to work on Front-End Engineering Design next year, ready for submission to the Falkland Islands Government in Q1 2013.
The 14/10-9 well will now be sidetracked to take cores in both the Casper and Sea Lion formations, after which it will be P&A. The rig will then move some 6.3 km to the southwest to drill in the PL004b licence, which following a recent farm-in agreement is operated by Rockhopper with a 60 per cent interest with fellow AIM company Desire Petroleum holding a 40 per cent interest. This well will target the most southerly extent of the Sea Lion main complex giving ailing Desire Petroleum a free ride into this portion of the only commercial discovery in Falklands waters as well as the Beverley prospect. Another discovery would certainly add real muscle to a development in these waters as well as generating some much needed good news for Desires shareholders who have, to date, suffered a run of dry holes.
