Both proposals require construction of pipelines and injection wells drilled into storage strata. The Gorgon project will utilise a 7km pipeline to transport carbon dioxide from the gas processing plant to the injection well sites. It is anticipated that nine injections wells will be drilled directionally from three drill pads to minimise disturbance of the environment.
The proposed Collie-Harvey pipeline is about 80km long and the Kwinana-Harvey pipeline 100km long. Where possible it is planned to utilise existing easements but the pipelines will still traverse industrial and populated areas, farmlands and land used in other ways.
