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: Screening multiple surfactants is performed by a screening method including passing foam compositions comprising a surfactant through a porous media while measuring pressure drop across the porous media until a first steady state pressure drop is achieved. Magnitude and frequency in oscillations of the first steady state pressure are measured. A gas is injected through the porous media while measuring the pressure drop across the porous media until a second steady state pressure drop is achieved. Magnitude and frequency in oscillations of the second steady state pressure drop are measured. Foam stability is determined based on the first steady state pressure drop, second steady state pressure drop, and magnitude and frequency of oscillations during the first and second steady states. Secondary oil recovery may include injecting a foam composition into an oil-containing reservoir, wherein the foam composition is based on results of the screening and properties of the oil-containing reservoir.

Abstract: A method and system for labeling and identifying a sample, including a rock core sample, after determining a physical primary label has been compromised is provided. The method includes labeling the sample by placing a physical primary label on the sample or sample container, creating a first rollout image of the sample for a secondary label, and storing the first rollout image in a secondary label digital database with a sample identifier. The method continues for identifying the sample after determining the physical primary label has been compromised by creating a secondary rollout image of the sample and searching the secondary label digital database using the second rollout image to create a plurality of matching scores using a machine learning or deep learning image matching technique. The matching scores are then evaluated to determine an identify of a sample and the sample is re-labelled using a replacement primary label.

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 recovering heavy oil from a reservoir may include placing one or more downhole mechanical heaters in an injection wellbore and injecting a fluid composition through the one or more downhole mechanical heaters. The fluid composition may contain a dialkyl ether. The fluid composition may further contain a surfactant and/or water in addition to dialkyl ether. The method may further include mechanically heating the fluid composition with the one or more downhole mechanical heaters to form a heated fluid composition, mixing the heated fluid composition with the heavy oil in the reservoir, decreasing a viscosity of the heavy oil, and collecting a mixture of the heated fluid composition and the heavy oil from a production wellbore.

Abstract: Mineralizing carbon dioxide for storage may occur in a wellbore. For example, a method of mineralizing carbon dioxide may include: introducing, through a first wellbore to a subterranean formation, a first solution including a metal salt and a metal catalyst; introducing a second solution including a brine, wherein the second solution has nanobubble carbon dioxide at least partially dispersed therein, and wherein the second solution is introduced after introduction of the first solution; injecting carbon dioxide gas thereby at least partially dispersing the carbon dioxide gas in the first solution, thereby forming dissolved carbon dioxide; generating mineralized carbon dioxide from the dissolved carbon dioxide, wherein the generating includes catalytically reacting the metal salt and the dissolved carbon dioxide using the metal catalyst, thereby forming the mineralized carbon dioxide; and depositing the mineralized carbon dioxide within the subterranean formation.

Abstract: A method for increasing CO2 sequestration efficiency in depleted reservoirs by increasing injectivity is provided. This method includes the steps of introducing a surfactant solution into an upper portion of the reservoir through an injection well and introducing CO2 to a lower portion through another injection well such that the CO2 and surfactant solution migrate away from the wells and intimately intermingle to form CO2-based foam in situ. The surfactant solution and CO2 may also be introduced through the same injection well, where the surfactant solution is introduced to an upper portion of the reservoir and the CO2 is introduced into a lower portion. The pressure may be maintained at a value less than the fracture pressure of the reservoir utilizing a pressure relief well.
