... Abstract The impact of non-swelling clays on Steam-Assisted Gravity Drainage (SAGD) performance was studied in this work. Two SAGD experiments were conducted on a Canadian bitumen by preparing the reservoir rocks with two different non-swelling clays; kaolinite (SAGD1) and kaolinite (90 wt...

... Abstract This study focusses on the impact of wettability alteration of reservoir clays on the overall efficiency of Steam Assisted Gravity Drainage (SAGD). Samples from two SAGD experiments were investigatedSAGD1, consisting of kaolinite in the oil-sand packing and SAGD2, consisting...

..., silt and shale components. The main authigenic cements are kaolinite, chlorite, calcite, ankerite and interstratified I/S. The facies described from core samples were adjusted with microfacies obtained from thin sections where permeabilities ranging 0.1 to 400 milidarcy, and porosities between 4 to 15...

... about a 1,000 times greater surface area:volume than a quartz sand grain. Fines are either cemented to the host grain or loosely attached within the pore network. Non-clay fines are typically not cemented at all, while kaolinite and illite are loosely attached thus making them susceptible to migration...

... damage which, as proven, is due to fine migration. Flow tests and the mineralogical analysis of some cores from the area have shown that there is a high content of clay particles such as kaolinite and "Mixed Layer" illite, which have a very special characteristic: they move through pores. When...
