Rockhopper’s exploration and appraisal activity in the North Falkland Basin has centred around licences PL032 and PL004, which contain the Sea Lion and the Isobel-Elaine fan complexes. It is envisaged that Sea Lion will be developed in two phases, with Isobel-Elaine viewed as a potential phase 3 development.

  • Rockhopper has made a number of discoveries in the North Falkland Basin
  • Sea Lion was the first oil discovery in the Falkland Islands (May 2010) and sits in around 450m of water
  • The field is well appraised
  • A number of associated discoveries form a wider part of the Sea Lion development (Casper, Casper South, Beverley and Zebedee)
  • Sea Lion has been independently audited to contain over 500mmbbls of recoverable oil on a 2C basis with a 3C of approximately 900 million barrels
  • There is material low risk near field upside in the area
  • As the field is so large, it is likely to be developed in phases
  • Isobel was discovered in 2014
  • The field requires appraisal and is likely to be developed after Sea Lion

Details of previous exploration campaigns

2010-12 campaign

In February 2010, the Ocean Guardian drilling rig arrived in Falklands water to carry out a multi-well drilling campaign. In the spring of 2010, Rockhopper (as operator) drilled its first exploration well on the Sea Lion Prospect which resulted in an oil discovery. The well was successfully flow tested in September 2010.

Following the successful flow test, a further eight exploration wells were drilled by Rockhopper across the Sea Lion Complex, six of those being discoveries. In addition, Rockhopper participated in a further five non-operated wells in the North Falkland Basin.

2015-16 campaign

In March 2015, the Eirik Raude rig arrived in the North Falkland Basin to commence a multi-well drilling campaign.

Through the course of 2015 and early 2016, oil discoveries were made at Zebedee, Isobel Deep and Isobel-Elaine.
