Activity Description |
---|
Quadrant Energy operates the Varanus Island oil and gas production and infrastructure facilities located offshore Dampier. Oil and gas is supplied to Varanus Island from a number of offshore petroleum reservoirs via several subsea pipelines. The Halyard gas field is located approximately 65 km west of Varanus Island, and currently comprises the Halyard-1 well connected via a flowline to the East Spar subsea infrastructure, from where gas is transported 65 km via pipeline to the East Spar gas plant on Varanus Island. Quadrant is proposing to install additional infrastructure to connect another well, Spar-2, to the existing Halyard subsea facilities. The Spar-2 well is located approximately 1.7 km west-southwest of the existing Halyard-1 well, and was completed in December 2010 but was not connected. To complete the connection, Greater East Spar infrastructure must be installed. Installation activities are expected to commence in Quarter 3, 2017, and run for up to 60 days. |
