Patent number: 11619113Abstract: Exemplary embodiments seek to eliminate or reduce fouling enabled by atmospheric oxygen entering the airspace of the well column. An inerting gas is used to flush atmospheric oxygen out of the well airspace. Once atmospheric air in the well gas-column has been replaced with an inerting gas, the well is sealed and pressurized with the inerting gas. The introduction of atmospheric oxygen back into the system through leaks is overcome by keeping a small, positive pressure-differential between the well-column gas pressure and the atmosphere. Results, as described herein, have shown the removal of atmospheric oxygen from the system can greatly reduce, or eliminate, both chemical and biological fouling as well as reduce or eliminate the need for well cleaning treatments.Type: GrantFiled: June 22, 2021Date of Patent: April 4, 2023Assignee: S.S.

The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.Type: GrantFiled: June 26, 2017Date of Patent: December 21, 2021Assignee: ChampionX USA Inc.Inventors: Duy T.

Patent number: 11193356Abstract: The provided method allows optimizing the fracturing design (frac design) while taking into account the two-dimensional modelling of the transport processes in the fracture. The generation of the fracturing design in a well comprises the steps of: obtaining data on hydraulic fracturing including the proppant pumping schedule and the fibre pumping schedule for various types of fibres; generating a degradation matrix for the various types of fibres; generating possible options of the hydraulic fracturing operation according to the fibre type and pumping schedule. Moreover, the method of hydraulic fracturing, which comprises generating a schedule of fracturing in a well, preparing a fracturing fluid containing carrier fluid, proppant, additives, and fibres, and pumping the fracturing fluid into the formation through the well following the selected (optimal) option of the fracturing operation, is provided.Type: GrantFiled: March 31, 2017Date of Patent: December 7, 2021Assignee: Schlumberger Technology CorporationInventors: Dmitry Viktorovich Badazhkov, Vladimir Alexandrovich Plyashkevich, Ivan Vladimirovich Velikanov, Dmitry Sergeevich Kuznetsov, Oleg Valerievich Kovalevsky, Vadim Ismailovich Isaev, Denis Viktrovich Bannikov

Patent number: 11162016Abstract: This invention is broadly concerned with compositions and processes for oilfield applications. More specifically, this invention relates to novel polymer constructed packages that, when pumped into a petroleum well, provide tunable characteristics of transformation and delayed self-assembly with each other under reservoir conditions to yield strong, elastic, bulk gel materials. The compositions comprise a polymer, assembling agents, and optional additives used for the re-assembly stage are uniformly-distributed within the initial gel particles. The polymer particle packages absorb water and swell upon exposure to water, thus exposing the “assembling agents” that enable re-assembly. Both swelling and re-assembly are proportionally controlled via compositions to be tunable to allow functional dispersion and subsequent self-assembly under various reservoir conditions.Type: GrantFiled: June 1, 2017Date of Patent: November 2, 2021Assignee: The Curators of the University of MissouriInventors: Jingyang Pu, Baojun Bai, Thomas Schuman

Patent number: 11149184Abstract: A method of recovering hydrocarbons comprises introducing a suspension comprising nanoparticles to a material and contacting surfaces of the material with the suspension. After introducing the suspension comprising the nanoparticles to the material, the method further includes introducing at least one charged surfactant to the material and removing hydrocarbons from the material. Accordingly, in some embodiments, the nanoparticles may be introduced to the material prior to introduction of the surfactant to the material. Related methods of recovering hydrocarbons from a material are also disclosed.Type: GrantFiled: August 30, 2018Date of Patent: October 19, 2021Assignee: Baker Hughes Holdings LLCInventors: Oleksandr V.

Patent number: 11105184Abstract: A completion apparatus for a wellbore includes several flow tools and an actuation mechanism. The flow tools have a piston defining first and second chambers with a housing. The chambers communicate with hydraulics so the piston are movable in response to the communicated hydraulics. A sleeve disposed in the housing is movable with the piston between first, second, and third positions. The sleeve can have a seat movable between two conditions for passing/engaging plugs. The sleeve in the first position closes off communication through the first and second ports, and the sleeve in the second position permits communication through the first port and closes off communication through the second port. The sleeve in the third position closes off communication through the first port and permits communication through the second port. The actuation mechanism is operable to communicate the hydraulics respectively with the chambers of the flow tools.Type: GrantFiled: March 22, 2019Date of Patent: August 31, 2021Assignee: Weatherford Technology Holdings, LLCInventors: Ryan R.
