  • Patent number: 10669829
    Abstract: Methods and systems for removing near wellbore damage in a hydrocarbon reservoir are described. In one example implementation, an antenna is positioned inside a wellbore in a location corresponding to a formation where near wellbore damage occurs. The wellbore extends from a surface of a hydrocarbon reservoir downward into the subterranean structure of the hydrocarbon reservoir. An electromagnetic (EM) wave is transmitted to the antenna. A portion of the EM wave is irradiated at the formation. The portion of the EM wave removes the near wellbore damage at the formation.

  • Publication number: 20190390101
    Abstract: A fracturing fluid including an aqueous base fluid having total dissolved solids between 100,000 mg/L and 400,000 mg/L, a polymer, a crosslinker, and at least one of a free amine and an alkaline earth oxide. In one example, the fracturing fluid may include a hydroxypropyl guar, a Zr crosslinker, and either a free amine such as triethylamine, or an alkaline earth oxide such as magnesium oxide. Optionally, the fracturing fluid may include a nanomaterial. Suitable example of a nanomaterial includes comprises ZrO2 nanoparticles. The viscosity and viscosity lifetime of fracturing fluids with polymer, crosslinker, and either a free amine or an alkaline earth oxide are greater than the sum of the effects of the individual components taken separately. This synergistic effect offers significant, practical advantages, including the ability to reduce polymer loading to achieve a desired viscosity, and the ability to achieve better formation cleanup after the fracturing treatment.
