  • Hydraulic fracking fluid for generating proppants in situ and fracking method with proppant generation in situ
    Patent number: 11578257
    Abstract: A hydraulic fracking aqueous fluid, including: water; one or more soluble calcium salts; a carbonate ion generating compound; and one or more soluble zinc salts. A method for fracking an underground formation using the hydraulic fracking fluid.
    Type: Grant
    Filed: March 4, 2021
    Date of Patent: February 14, 2023
    Assignee: YPF TECNOLOGIA S.A.
    Inventors: Gabriel Lombardo, Maria Laura Vera, Pablo Alejandro Raffo, Simón Marco, Marcos Eduardo Coustet, Roque Carlos Dietrich
  • Nanotracer for oil recovery comprising an occluded polynucleotide and method of preparation thereof
    Patent number: 11193368
    Abstract: Tracers for oil recovery, particularly fluorescent nanotracers comprising polynucleotides such as DNA strands. The tracer comprises a core-shell nanoparticle tailored according to the operation to be traced. It contains a fluorescent core comprising a target polynucleotide that allows the detection thereof in the field and a functionalized polymeric shell that provides increased stability in high salinity aqueous phases. A method for preparing said nanotracer by encapsulation of a polynucleotide.

  • Nanotracer for oil recovery and method of preparation thereof
    Patent number: 10995610
    Abstract: Tracers for oil recovery, particularly fluorescent nanotracers conservative in aqueous phases. The tracer comprises a core-shell nanoparticle tailored according to the operation to be traced. It contains a fluorescent core that allows the detection thereof in the field and a functionalized polymeric shell that provides increased stability in high salinity aqueous phases. A method for preparing said nanotracer. Given the nanotracer versatility, it can be used both for tracing fracking steps as well as meshes of secondary and tertiary recovery.
