| Description | Two complementary techniques for imaging flow, X-ray CT, and transport, PET, through rock cores have been applied experimentally. These were applied to the imaging of surfactant/polymer (enhanced oil recovery method) floods in Bentheimer (sandstone) rock cores. Via X-ray CT, a greater understanding of rock core aspect ratio on flooding performance was garnered - information that can help streamline and reduce wasted efforts in industrial surfactant/polymer flood worfklows. |
| Exploitation Route | Albeit applied to enhanced oil recovery, surfactant transport plays an important role in other, more topical, research areas - such as soil remediation. The techniques applied here can be thus extended and applied to these parallel fields with the goal of developing additional knowledge there. The work also demonstrated the possibility of performing more complex, multi-phase, experiments imaged via PET. These experiments can prove quite powerful as most 'realistic' flow scenarios contain multiple phases - within which, specific fundamental knowledge, such as dispersion in unsaturated porous media, can be investigated via imaging (direct imaging currently limited to micromodels). |
