Elizaveta Andreevna Inozemtseva 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).

  • Treatment fluid, method for formation treatment, method for reducing the proppant settling rate in the formation treatment fluid
    Patent number: 11345847
    Abstract: A fluid and a method for treating a subterranean formation penetrated by a wellbore. The method provides for injecting a treatment fluid for hydraulic fracturing, wherein the treatment fluid contains a low viscosity carrier fluid, a proppant dispersed in the low viscosity carrier fluid and a fiber blend with different stiffnesses that have silicone finishing. The method provides for improved dispersion of fibers, reduces the proppant settling rate and reduces the probability of fiber bridging in hydraulic fractures.
    Type: Grant
    Filed: August 1, 2016
    Date of Patent: May 31, 2022
    Assignee: Schlumberger Technology Corporation
    Inventors: Anastasia Evgenyevna Shalagina, Elizaveta Andreevna Inozemtseva

  • TREATMENT FLUID
    Publication number: 20170037306
    Abstract: Proppant transport assist in low viscosity treatment fluids. Treatment fluids and methods use fiber containing 0.1 to 20 wt % silicones to inhibit proppant settling without an unacceptable bridging tendency.
