Falkland Oil and Gas Limited (FOGL) has informed that the final results for the 14/20-1 “Isobel Deep” well, offshore the Falkland Islands, are expected in early June.
The well is being drilled with Eirik Raude drilling rig. According to FOGL, a zone of suspected elevated formation pressure was penetrated at the base of the current 12 ¼” hole section and oil shows were also encountered in this interval.
The operator, Premier Oil, has decided to run an additional casing string before drilling ahead through the main reservoir target to total depth. This scenario had been anticipated and the additional 9 5/8″ casing is already on the rig.
FOGL says that this additional activity will add approximately 10-15 days to the schedule and final results are now expected in early June.
