A method to measure acid diversion efficiency in rock samples. The method includes measuring a first porosity and a permeability of the rock samples. The method includes flooding a core region of the rock sample with a hydrochloric acid (HCl) system to create a wormhole, wherein during the flooding the HCl system penetrates from a first end of the rock sample to a second end of the rock sample to form the wormhole. The method includes measuring a second porosity, a pore size distribution, and a diffusion tortuosity of the rock samples with NMR. The method includes establishing a diversion index (DI) based off a ratio between the diffusion tortuosity in a first direction and the diffusion tortuosity in a second direction. The method includes determining the acid diversion efficiency based off the diversion index.

A method for carbon dioxide (CO) storage includes injecting a brine solution into a subterranean anhydrite-rich formation, then injecting carbon dioxide into the subterranean anhydrite-rich formation and reacting the carbon dioxide with the subterranean anhydrite-rich formation to form one or more minerals thereby sequestering the carbon dioxide in the subterranean anhydrite-rich formation. The temperature in the subterranean anhydrite-rich formation is from 300 Kelvin (K) to 365 K and the pressure in the subterranean anhydrite-rich formation is from 90 bar to 120 bar.

A method of hydrogen storage is described. The method includes injecting hydrogen into a subterranean banded iron formation, including magnetite, hematite, and/or pyrite, where the hydrogen is mainly hydrogen (H) gas based on the total volume of the hydrogen. Further, the subterranean banded iron formation includes mainly magnetite, hematite, and/or pyrite based on a total weight of the subterranean banded iron formation, where the hydrogen is adsorbed on the magnetite, the hematite, and/or the pyrite. Further, the method includes injecting ethylenediaminetetraacetic acid into the subterranean banded iron formation to release the hydrogen from the magnetite, the hematite, and/or the pyrite.

Preventing the flow of soil grains into oil and gas wells is highly desirable for the protection of hydrocarbon production. Geotechnical engineering solutions addressing this issue may utilize enzyme-induced precipitation methods to consolidate and increase shear strength. Methods may comprise: providing a mixture comprising urea, a urease enzyme, calcium chloride, magnesium chloride, and a cellulose; contacting at least a portion of the mixture with at least a portion of a subterranean formation; and forming a biomineral precipitate within the subterranean formation. The biomineral precipitate, comprised of a carbonate mineral and an evaporite mineral, may consolidate particles within the subterranean formation to form a consolidated body.

A drilling fluid includes an aqueous base fluid; 1 to 30 wt. % of an okra composition; 10 wt. % of clay particles; and 0.005 to 0.5 wt. % of a base, each wt. % based on a total weight of the drilling fluid composition. The okra composition is uniformly disposed on surfaces of the clay particles. The clay particles disposed with the okra composition are present in the drilling fluid composition in the form of a composite. A pellet made from the clay particles treated with the okra composition has a swelling value at least 75% less than a swelling value of the pellet in an aqueous composition that does not contain the okra composition, as determined by a linear swell meter. A method of making the drilling fluid composition.

A method of hydrogen storage and recovery includes injecting saline water into a subterranean gas storage cell in a subterranean geologic formation, including magnetite. The method further includes injecting a gas mixture having hydrogen gas at a positive pressure into the subterranean gas storage cell, and then storing a portion of the hydrogen gas in the magnetite under a storage condition. At least a portion of hydrogen is desorbed of the hydrogen gas from the magnetite by injecting a chelating solution into the subterranean gas storage cell.

A method of emulsion detection includes executing an oil production process from a volume of a formation. While executing the oil production process, conducting real-time spectral induced polarization (SIP) measurements of the volume of the formation to determine a real-time real conductivity value (RCV) of a matrix material in the volume of the formation. The method further includes determining an onset of water-in-oil (W/O) emulsion formation in the volume of the formation by analyzing the real-time RCV of the matrix material and optionally identifying the onset of the W/O emulsion formation when the real-time RCV first exceeds a first threshold value.

A thermochemical engine that includes a reaction chamber having a nitrite source inlet, an ammonium source inlet, and a gas outlet, and a gas-driven energy transducer coupled to the reaction chamber such that a gas produced in the reaction chamber moves the gas-driven energy transducer in a process of exiting the reaction chamber via the gas outlet. The thermochemical engine is configured to produce the gas under pressure by reacting in the reaction chamber a nitrite source comprising a nitrite ion and an ammonium source comprising an ammonium ion in the presence of water at a reaction temperature of 50 to 150° C.

An drilling mud composition is described, which includes an aqueous base fluid, a viscosifier, and a weighting material The drilling mud composition also includes an anti-sagging agent that comprises a dimethylamino methyl ester, such as methyl 5-(dimethylamino)-2-methyl-5-oxopentanoate. The anti-sagging agent may be used to prevent barite sagging, where barite is used as a weighting material. Small amounts of the anti-sagging agent may be used to maintain a low sag factor while drilling, and without causing unwanted increases in viscosity. The anti-sagging agent is effective for both vertical and inclined wellbores.
