A discovery was made five kilometres north-east of the present site of Statfjord C in 1976, and another the following year 22 kilometres to the north. Dubbed the Statfjord satellites, their development represented a departure from the Condeep platforms used on the main field.
More about geology and subsea
The Snorre licensees resolved in 1987 to develop this North Sea field with a tie-in to Statfjord for final processing, storage and export of the oil. On behalf of the partners in production licences 057 and 089, operator Saga Petroleum submitted a plan for development and operation (PDO) of Snorre to the Ministry of Petroleum and Energy that August. The proposed Snorre A production platform would have process facilities to part-stabilise the oil and gas through pressure and temperature reductions. Associated gas would be sold to the Statfjord group for use as fuel and to replace that field’s own production.
The Statfjord satellites
The Statfjord satellites is a collective term for three different reservoirs which have each been developed with their own solution, and tied back to the main field nearby. Statfjord North and East were developed as a single project, while Sygna forms part of the same licences as Statfjord East. The Statfjord north flank is regarded as part of the main licence. The satellites collectively increase reserves in the overall Statfjord area by about 15 per cent.
