(a) Ministerial Statement 800 (and the previous Ministerial Statement 748) requires at least 80% of reservoir CO 2 to be injected into the Dupuy formation over a five-year rolling average.
(b) No.
(c) The volume of CO 2 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.
(b) No.
