Anglia gas field


The Anglia gas field, is a natural gas field in the United Kingdom's continental shelf of the Southern North Sea. It is located in blocks 48/18 and 48/19 about 60 km east of the Lincolnshire coast. The reservoir is located at a depth of approximately subsea. The field was discovered in February 1972. Detailed seismic and appraisal well work were conducted in 1984. The reservoir was estimated to have 235 billion cubic feet of gas in place.

Owners

The original partners were Ranger Oil, Conoco, Elf Oil and Gas, Amerada Hess, and Triton Resources. In December 2010, Ithaca Energy became operator of the Anglia field by acquiring 30% stake in the field from GDF Suez E&P UK. Other partners are First Oil, Dana Petroleum 25%, and DEA AG.

Development

The field, at a cost of $120 million, was initially developed in 1991 through the Anglia A Normally Unattended Installation. The NUI had five producing wells including, at that time, the longest horizontal well drilled in British waters: the A3Z well has a 3,568 ft horizontal section. Production was through a 12-inch diameter pipeline to the Conoco operated LOGGS complex and thence to Theddlethorpe gas terminal. In 1993 the field was further development through the Anglia YM subsea template, with fluids produced via an 8-inch pipeline to Anglia A.
In November 2015 Ithaca Energy announced that production from Anglia would cease. In August 2018 all production through LOGGS and the Theddlethorpe gas terminal ceased.
