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

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

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]

The Easington Gas Terminal is one of six main gas terminals in the UK, and is situated on the North Sea coast at Easington, East Riding of Yorkshire and Dimlington. The other main gas terminals are at St Fergus, Aberdeenshire; Bacton, Norfolk; Teesside; Theddlethorpe, Lincolnshire and Rampside gas terminal, Barrow, Cumbria. The whole site consists of four plants: two run by Perenco, one by Centrica and one by Gassco. The Easington Gas Terminals are protected by Ministry of Defence Police officers and are provided with resources by the Centre for the Protection of National Infrastructure.

Theddlethorpe Gas Terminal (TGT) is a former gas terminal on the Lincolnshire coast on Mablethorpe Road at Theddlethorpe St Helen close to Mablethorpe in East Lindsey in England. It is just off the A1031 and next door to a holiday camp and Mablethorpe Seal Sanctuary and Wildlife Centre.

The United Kingdom's National Transmission System (NTS) is the network of gas pipelines that supply gas to about forty power stations and large industrial users from natural gas terminals situated on the coast, and to gas distribution companies that supply commercial and domestic users.

<span class="mw-page-title-main">Oil and gas industry in the United Kingdom</span>

The oil and gas industry plays a central role in the economy of the United Kingdom. Oil and gas account for more than three-quarters of the UK's total primary energy needs. Oil provides 97 per cent of the fuel for transport, and gas is a key fuel for heating and electricity generation. Transport, heating and electricity each account for about one-third of the UK's primary energy needs. Oil and gas are also major feedstocks for the petrochemicals industries producing pharmaceuticals, plastics, cosmetics and domestic appliances.
