The Planets gas fields are small natural gas producing areas in the UK sector of the southern North Sea, their names are associated with the planets and moons of the solar system. The fields started gas production from 1995, although some have now (2021) ceased operation.
The fields[edit]
The Planets fields are in Quadrants 47, 48 and 49 and have been owned and operated by a range of successive organisations. The fields are named after planets, minor planets, moons and asteroids. The planetary fields reservoir parameters are as shown.[1] [2] [3] [4] [5]

Developments[edit]
The fields were developed with an array of platforms and subsea completions. Production from the fields was routed via existing infrastructure to the onshore Easington and the (now closed) Theddlethorpe gas terminals.[6] [7] [8]
