Field Culzean Area Central North Sea Operator Maersk Development concept Platform or subsea? Transport concept Pipeline to nearby infrastructure Start-up 2011/12 Comments: In 2009 Maersk announced a ‘promising’ discovery at Culzean, an HP/HT gas/condensate field. Assessment of possible development options was ongoing, it said in Dec. The field lies in part-block 22/25a, about 20 km from BP’s Marnock and Lomond platforms and 25 km from Shell’s Shearwater. Water depth is 92 metres, so a wellhead platform or subsea facilities could be relevant options. Culzean may be one of the eight HP/HT fields which stand to benefit from tax concessions offered in Dec’s pre-budget report. Field Flyndre UK/NOR Area Central North Sea Operator Maersk Development concept Subsea? Transport concept 18 or 30km pipeline to Janice or Affleck? Start-up 2012 Comments: Maersk is drawing up plans to develop the Flyndre oil field which straddles the UK/Norwegian median line in blocks 30/14 and 30/13a (UK) and 1/5 and 1/6 (Norway). In Feb, according to partner Noreco, the three licences were close to agreeing on a joint study to clarify the commercial potential and preferred development scenario. The concept will be selected in H1 and a development plan submitted in H2, Noreco says. Maersk says only that several development options are being considered. A subsea tieback to the Janice FPU, possibly via the Affleck subsea facilities, looks likely. Field Foinaven South-West Area West of Shetland Operator BP Development concept Subsea Transport concept 11km pipeline to Foinaven FPSO Start-up 2011/12 Comments: BP discovered oil with Foinaven South-West exploration well 204/23-2 in 2008. In Apr it confirmed it was still looking at a two-well subsea tieback to the Petrojarl Foinaven FPSO. The discovery well, which was drilled in a water depth of 168 metres by semisub Paul B Loyd Jr, was plugged and abandoned. Separately GE is studying the introduction of subsea processing and power from shore on Foinaven. In Apr Teekay announced that the FPSO lease had been extended to 2021. www.intsok.com | 32
Field Maureen Redevelopment Area Central North Sea Operator Fairfield Development concept Subsea Transport concept Pipeline – 21 km to Andrew or 14 km to Varg Start-up 2011/12? Comments: Fairfield’s 16/29a-17 appraisal well on Maureen North-East last year failed to find commercial quantities of hydrocarbons. This may spell the end of redevelopment plans - the company said it would have to evaluate whether it still had a commercial project on its hands. This process was still under way in Mar. Development was previously planned to begin with Maureen North-East, which was believed to hold an estimated 27m bbl of oil in place, together with the underlying Morag reservoir. Funding of the well was largely taken on by Endeavour and Challenger Minerals under a farm-in deal. Fairfield also sees potential in the nearby Mary and Mabel fields – Mary has already been in production while Mabel is an undeveloped discovery. Fairfield’s preferred development solution was subsea facilities tied back either to BP’s Andrew hub or Talisman’s Varg in the Norwegian sector. Stand-alone mobile solutions were also evaluated. Maureen was originally developed by Phillips; it ceased production in 1999 when 226m bbl had been produced. Field Monkwell Area Southern North Sea Operator Dana Development concept Subsea Transport concept 10km pipeline to Cleeton? Start-up 2011 Comments: Dana seems to be confident of developing the small Monkwell gas field – it has ordered a subsea tree and control system from DrilQuip which the supplier put on display at Offshore Europe last year. Start-up is scheduled for 2011. But first comes a crucial appraisal well, which jackup GSF Labrador looks like spudding in May. Assuming the well is successful, Monkwell will be developed as a subsea tieback to a nearby host – an agreement has been reached with the host, according to Dana. The leading candidate appears to be Cleeton, some 10 km to the south-east, which already hosts several satellites. www.intsok.com | 33
