The International Tribunal for the Law of the Sea (ITLOS) on Saturday drew an ocean boundary favouring Ghana, ending the dispute which has slowed the development of oil fields and at times soured relations between the two oil-producing nations.
Tullow, which leads the TEN project, now expects to increase output from around 50,000 barrels per day (bpd) to 80,000 bpd.
“A clear ruling that does not alter the jurisdiction of any part of the TEN Development Area and is accepted by both countries is the best outcome Tullow could have hoped for,” said Barclays, which stuck to its “overweight” rating on the stock.
Tullow shares were up 6 percent at 189 pence by 0828 GMT, having earlier hit a four-month high of 192 pence.
“While positive from an operational sense regarding the potential return to drilling, this border ruling also removes a major corporate overhang which, in our view, has been delaying RBL refinancing,” brokerage Jefferies said.
Davy Research also said the company is likely to divest some of its 47 percent equity in the TEN project.
