  • Publication number: 20260071115
    Abstract: Described are techniques for preparing dispersions of nanobubbles in aqueous fluids, such as water or brine, under high pressure in order to create dispersions with large amounts of one or more gases that are normally immiscible with the aqueous fluid. The composition of the aqueous fluids can be adjusted to contain an optimized amount of gas at the desired pressure conditions. The gas can be present in the dispersion both as an amount dissolved in the aqueous fluid and as the dispersed nanobubbles. A thermodynamic model may be used to determine the amounts of gas that can be present in the nanobubble dispersion and/or used to determine or optimize a composition for the fluid.

  • Patent number: 12560054
    Abstract: Described herein are compositions, techniques, methods, and systems for sequestering carbon, for producing oil, for improved oil recovery, and for storing hydrogen by way of injecting aqueous mixtures into subterranean reservoirs. The aqueous mixtures include one or more carboxylates, which can represent a form of carbon dioxide and/or a form of hydrogen. The aqueous mixtures including carboxylates may also or alternatively be useful for increasing a viscosity of a fluid within the reservoir or modifying the wettability of rock within the reservoir to improve the availability and production of hydrocarbons contained within pores of the rock.

  • Patent number: 12031087
    Abstract: Described herein are techniques, methods, and systems for producing hydrocarbons from a reservoir and, particularly, from subterranean formations. The disclosed techniques employ oxygenated solvents, such as ketones, to improve or enhance oil or hydrocarbon production from subterranean formations. In some cases, ketones can be used in combination with surfactants to improve or enhance oil or hydrocarbon from subterranean formations.

  • Patent number: 10125591
    Abstract: Provided are oil recovery techniques, which may include enhanced oil recovery techniques in which a heated combination of water vapor (steam) and dimethyl ether (DME) vapor are injected into an oil reservoir, such as containing heavy oil and/or bitumen, to facilitate extraction of the oil from the reservoir.
