Project Overview
CO2CRC is currently developing the next stage of the Otway Project. Recognising the importance of saline aquifers for CO2 storage, CO2CRC has developed a “Stage 2” concept to better understand the non-structural trapping mechanisms in saline aquifers. It is proposed that a small volume of CO2-rich gas is injected, via a new well (CRC-2) into the Paaratte Formation, which represents a typical target with no clear structure closure, and low, medium and high permeability sands thinly interbedded with intraformational sealing lithologies.
This will allow the CO2CRC 1) to focus on investigating processes and kinetics governing CO2 dissolution, hydrodynamic trapping and geochemical reaction using the Huff-n-Puff approach and 2) to characterise and measure parameters (such as saturation and relative permeability) that affect the CO2 behaviour in saline aquifers using a set of dedicated monitoring tools. The Otway Project Stage 2 will expand the scope of the work by building on knowledge and facilities established for Stage 1. Stage 2 will also pave the way for future long term developments of the Otway project beyond 2010.
