Falkland Oil and Gas(LSE: FOGL) andRockhopper Exploration(LSE: RKH) have been on a roll over the past four weeks.
While the FTSE 100 has ticked lower by 0.6% over the past month, Rockhopper and Falkland Oil have added 25% and 8% respectively.
But is it time to take profits following these impressive gains, or should investors hold on for further growth?
Bright prospects
Falkland Oil and Rockhoppers gains over the past few weeks have been driven by recent exploration successes.
Last week, the two companies, along with their partnerPremier Oil, announced anew oil discovery at Isobel Deep in the North Falkland Basin, which exceeded expectations.
This discoveryhas led analysts to speculate that there could be up to1bn barrels of recoverable oil reserves under theseabedin the Falklands region.
Clearly, this is great news for Rockhopper and its smaller peer.
Its believed that Rockhoppers Sea Lion prospect will be producing an estimated 60,000 barrels of oil per day within five years. Recent discoveries indicate that Falkland Oil & Gas could beset to benefit from similar growth.
Plenty of work to be done
Unfortunately, while Rockhopper and Falkland Oil could be sitting on vast hydrocarbon reserves, the two companies are still years away from production.
And theres plenty of work to be done before either companys Falklands assets start generate cash.
Both Rockhopper and Falkland Oil are planning to begin oil production from the Falklands prospects, assuming everything goes to plan, by 2019. The recently revised field development plan will cost the two companies $2bn.
After this initial expenditure, it is expected the fields will start to generate their own cash flow, which will allow further development to take place.
High risk, high reward
Overall, if everything goes to plan, theres a chance that Falkland Oil and Rockhopper could return to their all-time highs when they finally start producing oil.
This indicates a gain of 545% for Rockhopper from presentlevels and a gain of 713% for Falkland Oil.
That said, the chances of this happening are slim. The two companies could just as easily see their shares fall to zero.
