Filed:

Nov 15, 2001

Appl. No.:

09/999292

Inventors:

George J. Hirasaki - Bellaire TX
Clarence A. Miller - Houston TX

Assignee:

Wm. Marsh Rice University - Houston TX

International Classification:

E21B 4326

US Classification:

166294, 166281

Abstract:

Methods of reducing the water permeability of a water producing zone in a subterranean formation are provided. The methods basically comprise introducing a polymeric surfactant and an inert gas into the water producing zone to thereby form a water permeability reducing foam therein. The polymeric surfactant has the property of facilitating the formation of the foam and the additional property of stabilizing the foam in the presence of flowing formation water.

International Classification:

C10G 1/04

US Classification:

208390

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.

International Classification:

C09K 8/584

US Classification:

507255

Abstract:

The invention relates to a hydrocarbon recovery composition comprising a combination of an internal olefin sulfonate and an alkoxy glycidyl sulfonate, more specifically a hydrocarbon recovery composition comprising surfactant and water, wherein the surfactant comprises a combination of an internal olefin sulfonate with a chain length of greater than C20 and an alkoxy glycidyl sulfonate selected from an ethoxylated glycidyl sulfonate and a propoxylated glycidyl sulfonate. Further, the invention relates to a method of treating a hydrocarbon containing formation, comprising (a) providing a hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation, wherein the composition comprises a blend of an internal olefin sulfonate and an alkoxy glycidyl sulfonate; and (b) allowing the composition to interact with hydrocarbons in the hydrocarbon containing formation.
