The search for new oil and CO

Residual oil zones (ROZs) could present a new, potentially large and commercially viable resource for Australia provide an avenue geological storage of carbon dioxide (CO2) through CO2 enhanced recovery (CO2-EOR). These reservoirs, which can contain moderate amount residual resemble water-flooded fields, be associated with conventional fields (brownfields) or occur no main pay zone (greenfields). Both types ROZ are currently produced CO2-EOR in the Permian Basin, USA, growing interest internationally, but our understanding occurrence economic viability production from ROZs is limited. We employing petrophysical methods to identify, map quantify potential resources ROZs, initially central Australian basins. Complementing this, we conducting series core-flooding experiments combined reservoir modelling investigate techno-economic feasibility producing storing these formations. aim establish test workflow characterising evaluating Australia. prove good targets CO2-EOR+, even carbon-neutral carbon-negative by using anthropogenic sources, such as blue hydrogen production.
