Question

I refer to Gorgon Gas Development Carbon Dioxide Injection System, and I ask:
(a) what is the anticipated lifespan of the Carbon Dioxide Injection System for the Gorgon Gas Development project;
(b) if the Gorgon Gas Development exceeds the lifespan of the Carbon Dioxide Injection System, will Chevron be required to source alternative CO2 removal or offset operations;
(c) what is the estimated capacity for CO2 storage in the Dupuy Formation on Barrow Island;
(d) given the more than 40 years lifespan of the Gorgon Gas Development Project, has an alternative location for a carbon dioxide injection been considered; and
(e) if no to (b), why not?

Answered on 31 October 2019

(a) - (b) Ministerial Statement 800 requires Chevron Australia to design, construct and operate a carbon dioxide injection system for the life of the project. The Environmental Protection Authority (EPA) Report 1221 for the Gorgon Gas Development  indicates that the lifespan of the proposal is 60 plus years.

(c) The EPA Report 1221 noted that in 2004 the then Department of Industry and Resources commissioned Curtin University to undertake a technical appraisal of the feasibility for injection of the CO2 from the development, including reviewing the investigation work undertaken by  . The appraisal found that the Dupuy Formation has adequate capacity to contain the CO2 from the injection system for the life of the project.

(d) See answer to (a) - (b) above.

(e) Not applicable
