Abstract: One method includes position an antenna inside a wellbore in a location corresponding to a formation where near wellbore damage occurs; wherein the wellbore extends from a surface of a hydrocarbon reservoir downward into the subterranean structure of the hydrocarbon reservoir; transmitting an electromagnetic (EM) wave to the antenna; and irradiating, from the antenna, at least a portion of the EM wave at the formation, wherein the portion of the EM wave removes the near wellbore damage at the formation.

Abstract: Embodiments provide methods and compositions for mitigating water production for hydrocarbon recovery. According to an embodiment, the method involves a treatment fluid composition. The treatment fluid composition includes a base liquid, a gelling agent, and a crosslinking agent. The treatment fluid composition is introduced downhole where it is positioned in a high permeability streak adjacent to a wellbore. After crosslinking, the treatment fluid composition blocks water in the high permeability streak from penetrating into the wellbore.

Abstract: A method and hydraulic fracturing fluid that is a viscoelastic surfactant (VES) fracturing fluid having a surfactant and an inorganic oxidizer salt for hydraulic fracturing of a geological formation. The VES fracturing fluid is provided through a wellbore into the geological formation to hydraulically fracture the geological formation to form hydraulic fractures in the geological formation. The method includes oxidizing organic material in the hydraulic fractures with the VES fracturing fluid.

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.

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.

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.
