Facility Details

The Jackson facility accepts production from approximately 40 oil fields containing about 182 oil wells through approximately 250 kilometres of pipelines and flowlines. Produced oil is dewatered and sent via the 797 kilometre 12 inch Jackson-Moonie pipeline and on to the Lytton oil refinery in Brisbane.

Jackson acts as the central collection and storage facility for several outlying satellite gathering areas such as Watson, Tickalara, Cooroo and Naccowlah.

The fields originally contained over 360 million barrels of oil in place of which about 110 million barrels will ultimately be recovered. To date about 95 million barrels has been produced.

The central facility comprises:

• oil processing inlet separators, dewatering tanks, evaporation ponds and skimming ponds
• centralised electrical power supply to beam pumps and ESPs at Jackson and Naccowlah facilities (Jackson 3.5MW - Naccowlah 5MW)
• oil storage (two tanks, 63,000 barrels total)
• shipping pumps.

Water is provided by bores and a flash evaporator plant and 4.5MW electricity generation capacity is on site.
