Latest Patents

Among his latest patents, Phelps has introduced groundbreaking techniques such as "In-situ cementation for profile control" and "In-situ silica cementation for profile control during steam injection." The first patent describes a method and composition for controlling the profile of a formation at temperatures exceeding 200°F. This involves injecting an aqueous solution of organoammonium silicate into a higher permeability zone, followed by a spacer volume of a water-immiscible organic solvent, and finally a water-miscible organic solvent containing alkylpolysilicate. This process results in the formation of silica cement in-situ, effectively closing the higher permeability zone to fluid flow. The second patent outlines a similar method, utilizing an aqueous solution of alkali metal hydroxide or ammonium hydroxide to achieve profile control during steam injection.
