摘要： Offshore systems and methods may be configured for oil production, offshore power generation, ammonia production, and carbon dioxide injection for EOR. For example, a method performed on an offshore facility may include: separating a produced hydrocarbon into a produced gas and a produced oil; combusting the produced gas to produce power and a flue gas; at least partially removing nitrogen from the flue gas to produce a carbon dioxide-enriched flue gas and a nitrogen-enriched flue gas; reforming a portion of the produced gas to produce a stream including hydrogen and carbon dioxide; at least partially separating the carbon dioxide from the stream to yield a carbon dioxide stream and a hydrogen stream; reacting the hydrogen stream and the nitrogen-enriched flue gas to yield ammonia; combining and compressing the carbon dioxide stream and the carbon dioxide-enriched flue gas; and injecting the compressed gas from the gas compressor into the gas reservoir.

摘要： A formation treatment fluid may include a wettability alteration agent, a solvent, an injection gas, and an optional foaming agent. The wettability alteration agent may include a fluorinated surfactant, a silicon-based surfactant, charged nanoparticles partially modified with fluorine containing groups, or combinations thereof. Methods for altering a hydrocarbon-bearing reservoir surface wettability may include providing the formation treatment fluid, injecting the formation treatment fluid into the hydrocarbon-bearing reservoir, and recovering fluids produced from the hydrocarbon-bearing reservoir.

摘要： A method of oil production after water flooding includes the steps of: forming at least one injection well and at least one production well in a reservoir; pumping enriched air (at least 30-100 mole-% oxygen with fogged water droplets) into the injection well, so as to maximize gravity segregation of gas/steam and gravity drainage of oil from an attic and/or pinch-out volume of the reservoir; and recycling produced carbon dioxide by injection into a man-made gas cap created around the at least one injection well. The enriched air preferably includes a mixture of 30-100 mole-% oxygen, 0-4 mole-% argon, 0-67 mole-% nitrogen and 0-70 mole-carbon dioxide gas.

摘要： System and method for the optimized production of hydrocarbons from shale oil reservoirs via cyclic injection to achieve an improved and optimal recovery of oil. The method can determine and optimize the composition of injected fluids to be injected, the rate, pressure and duration of injection, the production rate and pressure of produced fluids; can determine and utilize the optimum number of injection and production cycles; can determine the amount of soaking time (if any); and can determine the equipment design and operating characteristics to provide for the optimized injection of injection fluids, and the separation of produced fluids for both reinjection and delivery to sales or storage.

摘要： A method of subsurface sequestration of CO2 in a subsurface formation, the method including: producing formation water and hydrocarbons from a first well located within the first region while concurrently injecting an aqueous CO2 solution into a second well located within the second region, wherein the subsurface formation comprises a first region and a second region, the first region and the second region being fluidly connected, and the second region is at a greater depth than the first region and comprises at least one of the subsurface sequestration locations; and allowing the aqueous CO2 solution to sink as a negatively buoyant fluid below the formation water and the hydrocarbons, thereby sequestering the CO2 in the second region of the subsurface formation and wherein the aqueous CO2 solution has a greater density than the formation water and the hydrocarbons, making the aqueous CO2 solution negatively buoyant in the subsurface formation.
