Licence committee for unitisation

Norwegian Petroleum Museum

The licensees for the British and Norwegian sides of Statfjord held an informal meeting in December 1974 to discuss unitisation – an agreement on joint development and production of the field – and to determine its division between the two countries.

It had already been established in May that Statfjord extended across the North Sea boundary. Agreements on exchanging well and seismic survey data were entered into during May 1975. Conoco was operator for the UK licence and coordinated exploration drilling.

The first formal meeting took place in August 1975, when the Statfjord field licensees committee (SFLC) was created to take ultimate charge of the unitisation work. Each licensee had one member and an alternate on this committee. The UK licensees attended solely as observers without voting rights until a preliminary unitisation agreement was signed in June 1976.

This estimated that the Norwegians held 88.88 per cent of the field’s reserves while the British had 11.11 per cent. That division has later been adjusted by agreement.
