  • Publication number: 20210024814
    Abstract: A method for treating kerogen in a subterranean zone which includes the use of supercritical carbon dioxide or emulsions of liquid carbon dioxide and an aqueous fluid. The carbon dioxide or emulsions can further include oxidizers. The oxidizers can include inorganic oxidizers or organic oxidizers, for example an oxidizer including an organic cation and an oxidizing anion. Additional additives such as polymers, crosslinkers, clay inhibitors, scale inhibitors and corrosion inhibitors can further enhance the efficiency of the kerogen-treating carbon dioxide or emulsion.

  • Publication number: 20210024808
    Abstract: Unconventional hydrocarbon source rock reservoirs can contain the organic material kerogen, intertwined with the rock matrix. The kerogen can alter the tensile strength of the rock and contribute to higher fracture energy needs. To degrade kerogen and other organic materials, oxidizing gasses are dissolved in carbon dioxide (CO2) which is then used as part of a fracturing fluid. The oxidizing gasses can be dissolved directly in the CO2 or generated in situ using precursors.

  • Publication number: 20200224078
    Abstract: Embodiments relate to methods and compositions for controlling excess water production for hydrocarbon recovery. According to an embodiment, the method includes a treatment fluid composition. The treatment fluid composition includes a monomer and a latent acid. The treatment fluid composition is introduced downhole where it is positioned in a water-bearing region of a hydrocarbon-bearing formation. An acid catalyst is formed by hydrolysis or decomposition of the latent acid in the water-bearing region. The acid catalyst is used to polymerize the monomer to form a resin. The resin blocks water from permeating from the water-bearing region into the wellbore.

  • 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.
