Premier makes O&G discovery offshore Falklands

  • Exploration & Production

Premier Oil has announced that the Zebedee well (14/15b-5) in PL004b, offshore the Falkland Islands, discovered 81 feet of net oil-bearing reservoir and 55 feet of net gas-bearing reservoir. 

The well penetrated multiple targets in the Cretaceous F2 and F3 formations with a total hydrocarbon net pay of 136 feet. The pay is primarily located within two F2 sands:

·     The Hector sand, which contains 55 feet of net gas pay.

·     The Zebedee sand, which contains 79 feet of net oil pay. No oil-water contact was observed in Zebedee.

The reservoir at both the Hector and Zebedee intervals is of good quality and the above results are in line with prognosis. Good oil shows were recorded at the deeper F3 targets but at this location the sands are not well developed, Premier has said.

The well will now be plugged and abandoned as a successful exploration well. The Eirik Raude rig will then drill the first exploration test of the Elaine/Isobel fan complex in the southern part of the North Falkland Basin with the Isobel Deep well. The results of this well are expected in late April.

Andrew Lodge, Exploration Director said:  We are delighted to announce the discoveries in the Hector and Zebedee fans, which extend the play fairway further south from Sea Lion and the satellites. They will add further resource to future phases of development in the area. We now look forward to the results of the upcoming Isobel Deep well, potentially the highest impact well in this campaign.”
