Latest Patents

Among his latest patents, the invention titled "Crosslinking of swellable polymer with PEI" stands out. This invention is directed towards the development of stable and labile crosslinked water-swellable polymeric microparticles. These microparticles can undergo further gelation through covalent crosslinking in a transamidation reaction. The applications of this invention span across hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, the food industry, and papermaking. Importantly, the invention also serves as flocculation aids. The composition comprises expandable polymeric microparticles with both labile and stable crosslinkers, mixed with a fluid and an unreacted tertiary crosslinker such as polyethylene imine (PEI). This unique formulation allows for the particles to swell and form a stable gel, which has critical applications in petroleum production processes, enhancing oil recovery by diverting water to lower permeability regions.

Another remarkable disclosure is centered on "Delayed gelation of polymers." This technique presents methods and compositions that effectively delay polymer gelation in water flooding scenarios. By sequentially or co-injecting a carboxylate-containing polymer solution, a gel-delaying polymer, and a gelation agent into hydrocarbon reservoirs, prolonged delays—lasting weeks—are achieved.
