Premier Oil has been re-working the numbers for its Sea Lion development using an FPSO off the Falkland Islands.
One of Premiers officers has told a meeting of the Falkland Islands Offshore Hydrocarbon Environmental Forum that the work has resulted in an upgrade of the estimated reserves figure for the Sea Lion field which is now put at 394 million barrels of oil.
Also Premier has reappraised its FPSO mobilisation and subsea infrastructure costs.
Speaking to a meeting of the Falklands Islands Offshore Hydrocarbons Environmental Forum, Premier Oil's Ken Humphrey also told islanders of plans for a rig-sharing agreement involving Noble Energy for a three well exploration and appraisal drilling programme off the Falklands which is timetabled to take place in late 2014 and early 2015.
“He then outlined the current thinking on the Sea Lion Development, with a phased development of the exploitation of hydrocarbons, focussing first on the reserves in the north, followed by the south. The potential use of a Tension Leg Platform to reduce the footprint of subsea infrastructure is now being considered along with the FPSO option,” according to a report published by the Falkland Islands News Network.
Meanwhile Premier is working on environmental aspects of the Sea Lion development: Norway's Sintef research organisation is to be contacted to help prepare a weather study for the Sea Lion field area in the North Falklands Basin, to assess potential impacts of any possible oil spill, and a wave rider buoy is to be installed at the field location for up to three years to collect swell and other oceanographic data, the Falklands news network reports.
Acoustic monitoring devices which were installed in Sea Lion field area have been capturing data on cetacean movements for the last year and that data has now been retrieved and analysed prior to production of a final environmental report.
Also Premier is studying the implications of building a new jetty at Port Stanley in the Falklands to support its oil development.
Andy Duffy of Premier updated work on a Stanley Harbour Environmental Baseline Survey to support the construction of a temporary jetty and this data has been passed to Noble Energy which also plans to install a temporary dock at Stanley to support its 2014/15 drilling campaign.
The Falklands hydrocarbon forum heard that Noble plans to start building the temporary dock either later this year or early 2014, using a pre-fabricated floating concrete structure, using a 400 foot long by 100 foot wide barge, which is to be secured by piles and accessed via a causeway. Construction of the dock is expected to take up to six months, the Falklands news network has reported.
