Patent number: 9267075Abstract: The invention is directed to stable crosslinked water-soluble swellable polymers and methods for making same. More particularly, the invention relates to a composition comprising expandable polymeric particles having anionic sites and labile crosslinkers and stable crosslinkers, said particle mixed with a fluid and a cationic crosslinker that is capable of further crosslinking the particle on degradation of the labile crosslinker and exposure of the anionic sites so as to form a gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into target zone and when the heat and/or suitable pH of the target zone cause degradation of the labile crosslinker and the particle expands, the cationic crosslinker crosslinks the polymer to form a gel, thus diverting water to lower permeability regions and improving oil recovery.Type: GrantFiled: January 17, 2014Date of Patent: February 23, 2016Assignees: ConocoPhillips Company, University of KansasInventors: Ahmad Moradi-Araghi, James H. Hedges, David R. Zornes, Riley B. Needham, Huili Guan, Jenn-Tai Liang, Cory Berkland, James P. Johnson, Min Cheng, Faye Lynn Scully

Patent number: 9139762Abstract: The invention is directed to long lasting crosslinked water-soluble swellable polymers, methods for making same, and their uses. More particularly, the invention relates to a composition comprising expandable polymeric particles having cationic sites as well as labile crosslinkers and stable crosslinkers, said particle mixed with a fluid. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a target zones in the reservoirs and when the heat and/or a suitable pH in the reservoir cause degradation of the labile crosslinker and when the particle expands, the cationic sites in the polymer adsorb to negative sites of the rock in the formation, thus diverting water to lower permeability regions and improving oil recovery. However, many other uses are possible.Type: GrantFiled: February 18, 2014Date of Patent: September 22, 2015Assignees: ConocoPhillips Company, The University of KansasInventors: Ahmad Moradi-Araghi, James H.

Publication number: 20140238702Abstract: 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: ApplicationFiled: February 6, 2014Publication date: August 28, 2014Applicants: University of Kansas, ConocoPhillips ComapnyInventors: Huili GUAN, Cory BERKLAND, Ahmad MORADI-ARAGHI, Jenn-Tai LIANG, Terry M.

Publication number: 20140202693Abstract: 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: ApplicationFiled: December 30, 2013Publication date: July 24, 2014Applicants: The University of Kansas, CONOCOPHILLIPS COMPANYInventors: Huili GUAN, Cory BERKLAND, Ahmad MORADI-ARAGHI, Jenn-Tai LIANG, Terry M.

Publication number: 20140196894Abstract: The invention is directed to stable crosslinked swellable fluorescently tagged polymeric microparticles, methods for making same, and their various uses. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into target zone and when the heat and/or suitable pH of the target zone cause degradation of the labile crosslinker and the microparticles expand. The swelled polymer diverts water to lower permeability regions and improves oil recovery. The tags allow monitoring of the presence and concentration of the tagged microparticles and ultimately allow evaluation of the performance of such treatments. Detection of polymeric microparticles in producing wells can be instructive for teaching about the character and extent of thief zones in the subsurface. Better knowledge of the reservoir flow will enable improved application of the gel treatments, improved oil recovery, and allow improved forecasting using simulation modeling.Type: ApplicationFiled: October 22, 2013Publication date: July 17, 2014Applicants: University of Kansas, ConocoPhillips CompanyInventors: Cory BERKLAND, Huili GUAN, Ahmad MORADI-ARAGHI, Jenn-Tai LIANG, Terry M.
