Abstract: Techniques for generating electric power for well site operations include processing a hydrocarbon fluid produced from a subterranean formation, through a wellbore, and to a terranean surface into at least one acid gas; processing the at least one acid gas into hydrogen; generating, with the hydrogen, electrical power from a hydrogen engine; and providing the generated electrical power for use or storage to power at least one electrically-operated machine to perform at least one well site operation.

Abstract: A composition for a fracturing fluid may include a chelating agent, a polymeric gelling agent, and a base fluid. The base fluid in the fracturing fluid composition may be a produced fluid having a hardness content of at least 7,000 ppm. Method for treating a hydrocarbon-bearing formation may include introducing a fracturing fluid in the hydrocarbon-bearing formation. The fracturing fluid contains a chelating agent, a polymeric gelling agent, and a base fluid. The base fluid may be a produced fluid that has a hardness content of at least 7,000 ppm. The fracturing fluid may have a viscosity of at least 200 cp at 150° F., 100 1/s shear rate, and 300 psia when tested using model 5550 HPHT rheometer. After contacting the hydrocarbon-bearing formation, the viscosity of the fracturing fluid may drop near a range of 1 cP to 5 cP.

Abstract: Methods and systems for sequestering carbon dioxide and growing algae can include: producing fluids from a subsurface formation; separating the fluids into hydrocarbons and produced water; transferring the produced water to a treatment pond; transferring the hydrocarbons to a gas fractionation plant; separating the hydrocarbons resulting in a carbon dioxide side stream; and discharging the carbon dioxide side stream into the treatment pond.

Abstract: Fluids injected into a carbonate reservoir formation during Enhanced Oil Recovery (EOR) may include a foaming mixture that includes a zwitterionic surfactant, an omega-3-acid ethyl ester, and aqueous salt solution. The omega-3-acid ethyl ester may include eicosapentaenoic acid ethyl ester, docosahexaenoic acid ethyl ester, or combinations thereof. The foaming mixtures may be incorporated into methods for enhancing hydrocarbon recovery in a carbonate reservoir formation. The methods may include introducing the foaming mixture to the carbonate reservoir formation such that any hydrocarbon present in the carbonate reservoir formation is displaced by the foaming mixture and is recoverable from the carbonate reservoir formation.

Abstract: The application discloses foam compositions, methods to produce foam compositions, and methods to increase hydrocarbon production by displacing a hydrocarbon product with a foam composition. The foam composition includes an aqueous phase that typically includes an amphoteric surfactant and inorganic ions.

Abstract: Methods and systems for recovering hydrocarbon gas from a subterranean reservoir comprising a wellbore, the methods and systems comprising introducing solid carbon dioxide into the wellbore are described within.
