Low salinity surfactant nanofluids for enhanced CO2 storage application at high pressure and temperature
Abstract
CO2 storage and its containment security are key concern of a large-scale CCS project. One of the most important parameters affecting the CO2 storage potential is CO2/brine interfacial tension. In this work, we use low salinity surfactant nanofluids to demonstrate its potential application for CO2 storage at high pressure and temperature conditions by significantly lowering CO2/brine interfacial tension. The present work gives novel insight on the use of nanoparticles in CO2 storage application. We use Sodium dodecylbenzenesulfonate (SDBS) surfactant and ZrO2 nanoparticles for our formulation. Determination of interfacial tension were carried out using pendent drop method at 20 MPa and 70 °C and drop shape analysis were carried out using pendant drop plugin of Image J software.
