The objective of the project is to investigate/demonstrate the feasibility of utilising produced CO2 for re-injection in a geothermal field to provide the geothermal energy sector with the means to address the climate change challenge through CO2 utilisation/storage.
The main objective of the postdoctoral research project is to investigate and demonstrate the feasibility of utilising produced CO2 for re-injection in a geothermal field to:
- maintain and enhance reservoir pressure as the driving mechanism for the production of geothermal fluids, while storing the CO2 that is currently being vented to the atmosphere in most geothermal fields,
- test and demonstrate new monitoring technologies, such as the new environmentally friendly seismic monitoring EM-vibrators and the highly sensitive distributed fibre-optic acoustic sensing systems (DAS),
- increase reservoir permeability and productivity while suppressing scaling by artificial acidification,
- provide a real field environment for testing of supercritical CO2 injection into a carbonate reservoir and, simultaneously,
- provide the geothermal energy sector with the means to address the current climate change challenge through CO2 utilisation and storage.
This project addressed the efficiency of Foam-Assisted Chemical EOR. The question that was addressed in this project is whether we can improve the efficiency of surfactant flooding by using foam as a mobility drive.
Gas flooding is one of the most efficient Enhanced Oil Recovery (EOR) methods for extending the lifecycle of mature oil fields. Often gas injection is done under immiscible conditions. Immiscible Water-Alternating-Gas (iWAG) is often adopted to minimize gas gravity override and channeling through high permeability streaks and thus improve reservoir sweep efficiency. Unfortunately, gravity segregation might also occur during WAG injection as seen in laboratory experiments. Foaming of the gas is another, potentially more effective, way for improving gas sweep efficiency. Foam reduces gas mobility greatly by trapping gas in a discontinuous form within a continuous liquid phase. Foam can be effectively used as a mobility drive in an EOR process.
This project addresses the efficiency of Foam-Assisted Chemical EOR, i.e. Foam-Assistent Surfactant Flooding. The primary question which will be addressed in this project is whether we can improve substantially the efficiency of surfactant flooding by using foam as a mobility drive (oil bank formation, clean oil-emulsified oil ratio, ultimate oil recovery, mobilization and displacement mechanisms). The objective of the project is to investigate theoretically, numerically and experimentally the interplay of multiphase flow in porous media and transport of chemical species (surfactants, ions, etc.) at laboratory and field conditions.
