The Thevenard Island complex was discovered in 1985 with the Saladin-1 exploration well.
Production commenced in 1989. Currently producing ~1,700 bbls/d (gross).
Santos has participated in the Thevenard Island oil fields since 2000 when it acquired its interests from Shell Development (Australia) Pty Ltd.
Thevenard Island is a hub for six adjacent oil and gas fields, of which four are currently on production. Oil is produced from 21 wells from two offshore locations and nine unmanned offshore structures.
The facilities are capable of processing 120,000 barrels of oil per day and 18 million cubic feet of gas per day. Oil is stored at a 1 million barrel storage facility on the island and exported via an offshore tanker mooring.
