- The Fairley field is located some 45 kilometres northwest of Seria, in water depths of about 60 metres.
- The field consists of four separate accumulations spread over an area of 14 by 16 kilometres
- Gas is supplied to the Brunei LNG Terminal
- Global Industries: Subsea - Ampa Fairley rationalisation
- 1969 - Well Fairley-1 discovered gas in the Block 1 structure
- 1972 - Full scale development commenced
- 1982 - Installation of a fifth drilling platform
- The Fairley accumulations are trapped on the downthrown sides of three parallel down-to-basin growth faults, formed during the progradation of the Baram delta system. In Block 1 and 2 hydrocarbons are found in the A to B sands from 1,450 to 3,100 metres subsea (Early Piacenzian).
- Blocks 3, 4 and 5 contain hydrocarbons in the B to C sands from 1,680 to 2,770 metres subsea (Late Zanclian to Early Piacenzian) and Block 20 in the P to S sands between 2,360 to 3,050 metres subsea (Zanclian).
- Cores from the A, B and C sands are interpreted as fine to very fine, beach, shallow offshore bar and channel sands, ranging from 3 to 40 metres thick, with porosities and permeabilities of 17 to 26% and 10 to 500 mDarcy (0.01-0.5m2) respectively.
- The reservoirs range in age from Late Miocene in the southern accumulations to Late Pliocene in the northern, reflecting the seaward progradation of the palaeo-Baram coastline.
