Summary Information

  • Operator: Ithaca
  • Country: UK
  • Location: central North Sea
  • Production start: 2017
  • Partners:
  • Type: Oil & Gas
  • Estimated Reserves:
  • Production Volume:


  • The Greater Stella Area lies within United Kingdom Continental Shelf (UKCS) Block 30/06a, in the central North Sea. Block 30/06a is approximately 238km south east of Peterhead and 17km from the UK-Norway median line
  • The development includes the Stella, Harrier and Hurricane fields
  • The development scheme is likely to involve up to 5 production wells drilled from a sub-sea drilling centre on Stella and 2 further production wells drilled on Harrier. The Harrier centre will be tied back to the Stella where the hydrocarbons from both fields (oil and gas) will be combined
  • The development solution will involve the use of the FPF-1 semi-submersible floating production unit, owned by Petrofac
  • Gas is transported on the Central Area Transmission System ("CATS") to the Teesside Gas Processing Plant TGPP
  • The Vorlich field is being developed as an extension of the Stella develoment. Vorlich is a two-well development which will be tied back to the FPF-1 floating production facility


  • EPC Subsea: Manufacture of drill centre manifolds, riser base structures and export pipeline tie in structures
  • Technip: EPIC subsea contract
    • Detailed design and pipelay of a 33 kilometre 10” oil export and 63 kilometer 10” gas export pipeline to the production platform,
    • Various subsea works to the Stella main drill center and North drill center including;
    • Installation of manifolds, tee structures, flexible pipelay and spoolpiece components,
    • Installation of the mooring system to the production platform and design and installation of five-slot mid water arch.
  • Vallourec: Provision of seamless linepipe including coating and welding services
  • Applied Drilling Technology International: Manage development drilling and completion operations
