Publication number: 20240116789Abstract: Method of decomposing high molecular weight polymer downhole to prevent chelation of iron by residual high molecular weight polymer thereby producing flowback without iron contamination as chelated iron. A secondary method is also described to treat iron chelated produced water with oxidants at surface conditions, utilizing aluminum electrolytes, specifically low basicity polyaluminum chloride, to either co-precipitate residual polymer and bound iron, or to substitute chelated iron with aluminum in the polymer-metal complex, resulting in liberating of iron to enable neutral pH oxidation and removal by precipitation, coagulation, flocculation and physical separation. The produced water with removed iron can be then stored or re-used for other oilfield applications.Type: ApplicationFiled: October 5, 2023Publication date: April 11, 2024Applicant: CONOCOPHILLIPS COMPANYInventors: Jonathan KIESEWETTER, Ramesh SHARMA, Paul CARMAN

Patent number: 11353524Abstract: A system for measuring magnetic field gradients comprising a multi-bay support structure with a series of raised contact shoulders separated from each other by voids. An optical fiber is spaced along the length of the multi-cell support structure and traverses all the raised contact points and voids. The optical fiber has a plurality of Fiber Bragg gratings (FBGs) spaced lengthwise, each FBG suspended in a void. In addition, a plurality of ferromagnetic members are strung onto the optical fiber, each suspended in a void. Magnetic field gradients act on the ferromagnetic member to create localized tension in the optical fiber. The FBG's refractive indices are monitored, tension is calculated therefrom, and the tension is correlated to the magnetic field gradient. This greatly simplifies mechanical, optical, electronic and computational complexity and is bay suited for any FOSS array for measuring magnetic fields using many dense measurement points.Type: GrantFiled: July 20, 2020Date of Patent: June 7, 2022Assignee: U.S.A, as Represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Scott Michael Strutner, Anthony Barra, Gregory Paul Carman, William Lance Richards, Francisco Peña
