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.

Patent number: 9139760Abstract: The invention is directed to stable crosslinked water-soluble swellable polymers, 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 that is capable of further crosslinking the microparticle on degradation of the labile crosslinker so as to form a stable gel.Type: GrantFiled: December 9, 2013Date of Patent: September 22, 2015Assignee: ConocoPhillips CompanyInventors: Ahmad Moradi-Araghi, David R.
