NCCS Webinar - CO₂ mobility control – Modelling of CO₂ foam core flooding experiments" (Task 11)

Presenter: Alv-Arne Grimstad, Senior Research Scientist, SINTEF Industry

Description/purpose
The mobility contrast between injected CO₂ and the resident brine in a storage formation is typically high. This is unfavourable for efficient and stable displacement of brine during the CO₂ storage operation. Efficient mobility control for the injected CO₂ will improve sweep and reduce risk of early break-through of CO₂ in pressure management wells, leading to higher effective storage capacity.

In this webinar we present results from simulation of core-flooding experiments with several commercially available surfactants that generate CO₂-brine foam and therefore could be candidates for implementation of CO₂ mobility control in storage operations. The simulations show how high/low partition coefficient, high/low mobility reduction factor and high/low adsorption interact to give markedly different behaviour for the time-development of the surfactant concentration in the core and for the resulting effect on the gas mobility.
