Abstract
The main issue in heavy oils enhanced recovery methods is to reduce their viscosity in order to get a<br>better mobility. This is commonly obtained by blending the oil with light hydrocarbons. Co-solvents are<br>good candidates to improve the hydrocarbon recovery efficiency especially in miscible processes.<br>However, the effect of co-solvents on miscible flooding of heavy oil reservoirs at different pore geometries<br>is not well understood.
