Abstract: The invention relates to a hydrocarbon recovery composition, which composition contains: a) a first anionic surfact ant selected from the group consisting of a propoxylated primary alcohol carboxylate and a propoxylated primary alcohol glycerol sulfonate; and b) a second anionic surfactant selected from the group consisting of a propoxylated primary alcohol carboxylate and a propoxylated primary alcohol glycerol sulfonate, and wherein the first and second anionic surfactants are different. Further, the invention relates to an injectable liquid containing the hydrocarbon recovery composition and a method for treating a hydrocarbon containing formation.

Abstract: A method for processing a bitumen froth comprising bitumen, water and solids including fine solids for reducing the solids concentration in diluted bitumen is provided comprising diluting the bitumen froth with a hydrocarbon diluent to form a dilfroth; adding a sufficient amount of a silicate to the dilfroth to cause a substantial amount of fine solids to associate with the water instead of the diluted bitumen; and allowing the diluted bitumen to separate from the water containing the substantial amount of fine solids to produce a dilbit having less than 3 percent by weight solids.
