+++ History

  • 1969 - Well Fairley-1 discovered gas in the Block 1 structure
  • 1972 - Full scale development commenced
  • 1982 - Installation of a fifth drilling platform

+++ Geology

  • 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.
