CCS world projects: Otway Project

Project Overview

The CO2CRC has developed a research project which involves extracting CO2 and methane gas from an existing well, separating these gases in a temporary surface separation plant and compressing the CO2 to a supercritical state in a compressor/refrigeration unit. This condensed CO2 will then be transported and injected into a depleted natural gas field where it will be monitored by the CO2CRC. A comprehensive monitoring program across the atmospheric, near surface and subsurface domains is being planned. It is estimated that 100,000 t of CO2 will be injected over 1-2 years and monitoring and modeling activities will continue post injection for several years.
