Andrey Vladimirovich Yakovlev has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10662366
    Abstract: Well treatment compositions comprise water, a polysaccharide and cellulose fibers. The cellulose fibers may have lengths between 100 nm and 10 mm, and diameters between 4 nm and 40 ?m. The compositions may be used as spacer fluids during well cementing operations. The spacer fluids may prevent commingling of a cement slurry with a drilling fluid. The drilling fluid may be water-base, oil-base, synthetic-base or an emulsion.
    Type: Grant

    Date of Patent: May 26, 2020

  • Patent number: 10421897
    Abstract: This method is designed to facilitate the well treatment with the possibilities for non-uniform/heterogeneous proppant placement in the extended and branched fractures produced by hydraulic fracturing. The essence of the method is to inject a proppant-bearing gel into the wellbore drilled into a productive formation. The low-viscosity fracturing fluid is injected into the wellbore together with the gel fluid (simultaneously or in turns). The method also provides for the injection of gas into the proppant-bearing gel and/or the low-viscosity fluid. The gas can be injected upstream of the junction point, at the junction point, or downstream of the junction point of the flows of the proppant-bearing gel and the low-viscosity fluid. The method further provides for the division of the gel fluid into the separate agglomerates with their subsequent injection into the fractures in the subterranean formation to form the proppant structures in the fracture.

  • Publication number: 20180148630
    Abstract: Cement slurry compositions comprising water, an inorganic cement and additive comprising nanocrystalline cellulose, microcrystalline cellulose, cellulose fibrils, or bacterial nanocellulose or combinations thereof have reduced fluid loss values. Such compositions may be prepared and placed in subterranean wells. The compositions are suitable for use during primary cementing or remedial cementing operations.

  • Publication number: 20160340573
    Abstract: A technique facilitates a well treatment, such as a well stimulation. The technique comprises injecting a gel containing proppant into a wellbore extending into a subterranean formation. Additionally, a low viscosity fluid is injected into the wellbore with the gel either simultaneously or separately. An additive or additives may be used to maintain the gel in the low viscosity fluid. The technique further comprises separating the gel into slugs and then causing the slugs to flow into fractures in the subterranean formation.
