Experimental study on stability and rheological properties of aqueous foam in the presence of reservoir natural solid particles

Gas injection and especially CO2 flooding has been applied in many oil reservoirs globally to increase oil recovery factor in addition to its environmental friendly aspects. However, difference between fluid viscosities and densities, can cause interface instability where gas override and fingering may expedite gas breakthrough. Different types of foam have been proposed to improve interface stability. Yet, a major uncertainty is interaction of...
