An initial fluid of hydrochloric acid and water was pumped down the well to dissolve carbonates and then followed by the main fracture fluid which was 99.6 per cent water with friction reducers and clay stabilizers making up the remaining 0.4 per cent of the fluid.
This 0.4 per cent of fluid included up to 15 chemicals that are listed in the Material Safety Data Sheets attached to the Environmental Management Plan approved by the Department of Mines and Petroleum, and available on the operator's (Buru Energy) website at
