Facility Details

Santos has participated in the East Spar field since 1996. The field currently has one remaining production well and is expected to cease production during 2005.

The production facilities are tethered to a navigation, control and communications buoy housing power generation, chemical inhibition and communication equipment.

Gas is sent to the Varanus Island processing facility via a 63 kilometre multiphase pipeline. Condensates are removed and stored and the raw gas is processed into sales quality gas.

The processing facility consists of two sales gas trains and a common stabiliser with a total installed capacity of 2 x 100 million standard cubic feet of gas per day and 8,000 barrels of condensate per day. Sales gas is sent to mainland Western Australia via two 100 kilometre sales gas pipelines which connect into the Dampier to Bunbury and Goldfields Gas Transmission trunk lines.
