Patent number: 11820939Abstract: The instant application relates to nanogels or compositions that hold multivalent metal ions until some level of nanogel degradation has occurred, then slowly release the multivalent metal ions for gelation with carboxylate containing polymers. Compositions comprising such nanogels, together with polymers that can be crosslinked with multivalent metal ions, allow the deployment of such mixtures in various applications, and greatly increased gelation times.Type: GrantFiled: June 22, 2022Date of Patent: November 21, 2023Assignees: CONOCOPHILLIPS COMPANY, UNIVERSITY OF KANSASInventors: Huili Guan, Cory Berkland, Ahmad Moradi-Araghi, Jenn-Tai Liang, Terry M.

Patent number: 11814578Abstract: The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g, in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.Type: GrantFiled: May 13, 2021Date of Patent: November 14, 2023Assignees: CONOCOPHILLIPS COMPANY, UNIVERSITY OF KANSASInventors: Huili Guan, Cory Berkland, Ahmad Moradi-Araghi, Jenn-Tai Liang, David R.

Publication number: 20220348817Abstract: The invention is directed to stable and labile crosslinked water swellable polymeric microparticles that can be further gelled by covalent crosslinking in a transamidation reaction, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker comprising PEI or other polyamine based tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker and swelling of the particle, so as to form a stable gel.Type: ApplicationFiled: July 13, 2022Publication date: November 3, 2022Applicants: CONOCOPHILLIPS COMPANY, University of KansasInventors: Ahmad MORADI-ARAGHI, Min CHENG, Riley B.

Patent number: 11401455Abstract: The invention is directed to polymers that self-crosslink at acidic pH or can be crosslinked by phenolic agents in brine. Such polymers have lower viscosity and can be pumped deep into reservoirs, where they will cross link in situ, thus increasing their viscosity and/or form a gel and blocking thief zones. Methods of making and using such polymers are also provided.Type: GrantFiled: September 12, 2021Date of Patent: August 2, 2022Assignees: CONOCOPHILLIPS COMPANY, UNIVERSITY OF KANSASInventors: Huili Guan, Cory Berkland, Ahmad Moradi-Araghi, Jenn-Tai Liang, Terry M.

Publication number: 20200385629Abstract: The present disclosure provides nanosized scale inhibitors (NSI) that can extend a well treatment lifetime with high scale inhibitor retention and the ability to provide slow and sustained scale inhibitor release. The NSI can be in the form of particles where the particle size is in the nanometer range, the NSI can be suitable for applications in both formation rock and fractures. During hydraulic fracturing, the NSI can be mixed and pumped with the fracturing fluid into formation rock and fractures as a one-step process to cut the treatment cost, and the NSI can penetrate readily into the secondary fracture networks created in tight shale formations.Type: ApplicationFiled: December 8, 2017Publication date: December 10, 2020Applicant: The Texas A&M University SystemInventors: Jenn-Tai Liang, Huili Guan
