Parliamentary Questions


Question On Notice No. 347 asked in the Legislative Assembly on 25 November 2021 by Mr R.S. Love

Question Directed to the: Minister for Environment
Parliament: 41 Session: 1


Question

I refer to the Gorgon gas project, and I ask:
(a) How much CO2 was required to be sequestered at the Barrow Island site each year under the original project approvals;
(b) Has this figure changed and if so, what was the change and what was the date of each change;
(c) How much CO2 has been sequestered in each year;
(d) What is the shortfall in each year and what is the total shortfall; and
(e) What agreement has the state made with Chevron to address this shorfall?

Answered on 15 February 2022

(a) Ministerial Statement 800 (and the previous Ministerial Statement 748) requires at least 80% of reservoir CO2 to be injected into the Dupuy formation over a five-year rolling average.

(b) No.

(c) The volume of CO2 injected to date is: 2019 = 890,240 tonnes, 2020 = 3,517,143 tonnes, 2021 = 545,112 tonnes.

(d) Ministerial Statement 800 requires a five-year rolling average, therefore an annual shortfall figure cannot be determined. The shortfall over the five-year rolling average, 18 July 2016 to 17 July 2021, is 5,233,533 tonnes.

(e) Chevron has reported its intention to offset the shortfall.
