Note: bcm = billion cubic metres, bcf = billion cubic feet
Developments
The fields were developed with an array of platforms and subsea completions. Production from the fields was principally routed via existing infrastructure to the onshore
Bacton gas terminal
The Bacton Gas Terminal is a complex of six gas terminals within four sites located on the North Sea coast of North Norfolk in the United Kingdom. The sites are near Paston and between Bacton and Mundesley; the nearest town is North Walsham.

The pipeline from Lancelot to Bacton is known as the LAPS pipeline (Lancelot Area Pipeline System).
The Lancelot installation also provided an export route for gas from the Durango and Waveney fields.
