Reservoir engineering of in-situ carbonation: a feasibility study
Insitu carbonation turns carbon dioxide (CO2) into rock that is permanently stored underground! Insitu carbonation is therefore a technology that could be used to fight climate change.
Insitu carbonation involves pumping CO2 underground where it reacts with subsurface rocks. This project examines the reservoir-engineering aspects of this technology, in order to clearly identify the benefits, critical drivers of success and key obstacles that may be present in full-scale commercial implementations. Aspects such as the type of injectate (for example, super-critical CO2 or carbonated brine), the amount of water used, the pumping and pipeline requirements, the number of wells and their locations and completions, along with any fracking requirements will be explored. This will allow assessment of when and where insitu carbonation may be feasible.
