Quadrant Energy

Quadrant was formed in June 2015 after the acquisition by Macquarie Capital and Brookfield Asset Management of Apache Corporation’s Australian assets, with the executive team was carried over from the previous Apache ownership. The final price of the transaction was reportedly $US1.9 billion ($2.5 billion), and at the time of the announcement Quadrant was owned 50:30:20 by Brookfield, Macquarie, and AMB Holdings respectively.

The company had a primary focus on activities in the Exmouth and Carnarvon Basins offshore of north Western Australia.

In 2018, the company was acquired by Santos.
