Abstract: A method for sequestering CO2 in a subterranean formation and a method for sequestering CO2 in a subterranean formation during an enhanced oil recovery treatment include preparing a solution comprising CO2 and from 0.01% by weight (wt. %) to 10 wt. % of a CO2 soluble alkoxylate surfactant based on the total weight of CO2, processing the solution through a dispersing unit in fluid communication with an injection well, and injecting the dispersion into the injection well of the formation, thereby sequestering CO2 in the formation. The method for sequestering CO2 in a subterranean formation during an enhanced oil recovery treatment includes introducing an enhanced oil recovery treatment to the formation. A system for sequestering CO2 in a formation includes an injection well in fluid communication with a formation, an injection unit, and a dispersing unit that is in fluid communication with the injection unit and the injection well.

Abstract: A method of enhancing heat transfer and energy efficiency in a geothermal reservoir includes injecting a carbonated fluid to the reservoir, injecting a first salt solution and a second salt solution into the reservoir, and increasing the temperature of the reservoir by reacting the first salt solution with the second salt solution to provide heat. The carbonated fluid injection decreases a temperature of the reservoir. The second salt solution is reactive with the first salt solution under the conditions in the reservoir after the injecting. A system of enhancing heat transfer and energy efficiency in a geothermal reservoir includes an injection system in fluid communication with an injection well. The injection system is configured to alternate the injection of the carbonated fluid and the first salt solution and second salt solution.

Abstract: A method for water drainage of a substrate includes creating, on a surface of the substrate, a designated hydrophobic region having hydrophobic surfaces of a hydrophobic film. Electronic circuitries are fabricated in the designated hydrophobic region of the substrate. The method further includes creating, on the surface of the substrate, a designated hydrophilic region having hydrophilic surfaces of the substrate. A drainage channel is formed in the designated hydrophilic region. The method further includes facilitating, based on capillary imbibition of the drainage channel, fluid flow from the designated hydrophobic region to a drainage/evaporation port to prevent damage of the electronic circuitries by moisture accumulation in the designated hydrophobic region.

Abstract: Described is a method for enhanced carbon dioxide (CO2) sequestration in geological formations. The method includes dissolving CO2 in a low salinity fluid to form a CO2-brine solution. The low salinity fluid includes sodium (Na+) ions and sulfate (SO42−) ions. The CO2-brine solution is injected into a geological formation, and the CO2 reacts with the geological formation to produce solid carbonate minerals for CO2 sequestration.

Abstract: A method for selectively optimizing water chemistry within a wellbore may include positioning a system tubing in the wellbore. The system tubing may include an electrochemical cell, a first chamber, and a second chamber. The method may also include injecting a fluid into the electrochemical cell and directing an electrical current into the electrochemical cell wherein the fluid separates by charge into a first fluid and a second fluid. The method may also include passing the first fluid into the first chamber and the second fluid into the second chamber. Also, the method may include rotating the system tubing, wherein the first fluid flows from the first chamber to the wellbore though a first radial conduit and the second fluid flows from the second chamber to the wellbore through a second radial conduit.

Then, a mixture including water and a second set of nanoparticles having a size ranging from about 1 to 10 nm is introduced to a second target zone, located in a medium permeability layer of the stratified subterranean wellbore. A second stimulation including acoustic waves having a frequency range of 100 Hz to 1 kHz is provided to the second set of nanoparticles to promote reacting.
