Globally, for the development of bitumen oils thermal steam treatment is considered, since this technology is considered the most effective, but it has a number of problems with the presence of clay minerals in the rock. When clay minerals come into contact with steam they swell, leading to a decrease in the permeability of the reservoir, and therefore a decrease in the final oil recovery. This work assesses the influence of clay mineralization content on the degree of oil displacement under thermal steam treatment by conducing filtration experiments. Steam injection experiments containing low oil saturations of less than 2% resulted in no oil displacement. A solvent based on aliphatic and polar fragments was tested to extract oil in such low-oil saturated systems. Keywords: steam injection; bitumen oil; clay minerals; solvent; oil displacement.
