Abstract

A series of visual experiments were performed to better understand and study the important parameters affecting the instability of the diffusive layer in CO2 sequestration. A vertical, two-dimensional Hele-Shaw setup composed of a flat glass plate and a flat Al plate was designed to investigate the instability of saturated layer. The set up was partially filled with brine with salinity of 20 wt.% containing pH sensitive dye of litmus powder. CO2 was introduced into the top of Hele-Shaw cell with the initial pressure of 100 psi. Experimental results showed the onset of instability and the natural convection phenomenon when the start point of CO2 fingering and its propagation through the water phase were recorded.
