Title: George M Holzwarth: Innovator in Oil Recovery Technologies
Introduction
George M Holzwarth is a notable inventor based in Linden, NJ (US). He has made significant contributions to the field of oil recovery, holding a total of 2 patents. His work focuses on innovative processes that enhance the efficiency of oil extraction from subterranean formations.
Latest Patents
Holzwarth's latest patents include groundbreaking methods for oil recovery using modified heteropolysaccharides in buffered brine. The first patent describes a process that utilizes a modified aqueous saline heteropolysaccharide solution as a mobility control agent. This solution contains at least 0.5 wt. % of inorganic salts and is stabilized against loss of pyruvate groups during heat treatment. The process involves preparing an aqueous solution with heteropolysaccharide and inorganic salts, adding a buffer to maintain a pH between 6.5 and 10.0, and heating the solution while controlling the pH. This innovative approach prevents viscosity loss, ensuring effective oil recovery.
The second patent focuses on recovering crude oil using stabilized saline heat-treated heteropolysaccharide solutions. These solutions also contain at least 0.5 wt. % of inorganic salts and are designed to maintain viscosity during heat treatment. The stabilization process includes preparing an aqueous solution, removing oxygen, and heating in an inert atmosphere. This method results in improved filterability and eliminates cell debris, further enhancing the oil recovery process.
