Abstract: Methods of stimulating a hydrocarbon well are disclosed herein. The hydrocarbon well includes a wellbore that extends within a subterranean formation and a tubular that extends within the wellbore and defines a tubular conduit. The methods include retaining a sealing structure within the tubular conduit and, during the retaining, stimulating a zone of the subterranean formation. Subsequent to the stimulating, the methods include fluidly isolating the zone of the subterranean formation from the uphole region by at least partially sealing the plurality of perforations. Subsequent to the fluidly isolating, the methods include moving the sealing structure in a downhole direction within the tubular conduit. The methods also include repeating the retaining, the stimulating, the fluidly isolating, and the moving a plurality of times to stimulate a plurality of corresponding zones of the subterranean formation.

Abstract: Hydrocarbon wells include a wellbore, a fracture that extends from the wellbore, and an electromagnetic contrast material positioned within the fracture. The hydrocarbon wells also include a downhole electromagnetic transmitter, which is configured to direct an electromagnetic probe signal incident upon the electromagnetic contrast material, and a downhole electromagnetic receiver, which is configured to receive an electromagnetic resultant signal from the electromagnetic contrast material. Methods for monitoring fracture morphology of a fracture that extends from a wellbore of a hydrocarbon well include flowing an electromagnetic contrast material into a fracture and generating an electromagnetic probe signal. The methods also include modifying the electromagnetic probe signal with the electromagnetic contrast material to generate an electromagnetic resultant signal. The methods further include receiving the electromagnetic resultant signal and determining the morphology of the fracture.

Abstract: A method and system for liquefying a methane-rich high-pressure feed gas stream using a first heat exchanger zone and a second heat exchanger zone. The feed gas stream is mixed with a refrigerant stream to form a second gas stream, which is compressed, cooled, and directed to a second heat exchanger zone to be additionally cooled below ambient temperature. It is then expanded to a pressure less than 2,000 psia and no greater than the pressure to which the second gas stream was compressed, and then separated into a first expanded refrigerant stream and a chilled gas stream. The first expanded refrigerant stream is expanded and then passed through the first heat exchanger zone such that it has a temperature that is cooler, by at least 5° F., than the highest fluid temperature within the first heat exchanger zone.

Abstract: Disulfide solvents may be particularly effective for dissolving deposits comprising elemental sulfur, but the extreme odor of these solvent may make their use rather problematic. Solvent blends comprising at least one disulfide solvent, amine solvent, ketone solvent, and ester solvent may afford a less obnoxious odor and not appreciably compromise the sulfur dissolution capabilities. Surfaces contacted with such solvent blends or at least partially spent variants thereof may exhibit excessive odor due to loss of one or more of the amine, ketone, or ester solvents. Excessive odor resulting from a solvent residue upon a surface may be alleviated by contacting the surface with at least one oxidant. Odor balance may also be restored to at least partially spent solvent blends by introducing additional ester solvent, which may convert a biphasic mixture into an emulsion comprising the disulfide solvent.

Abstract: Oxygen-containing graphenic nanomaterial (OGN)-doped novolac polymers suitable for producing graphitized carbon may be synthesized based on a correlation between (a) the amount of OGN and/or the oxygen content of the OGN and (b) at least one property of a resultant graphitized carbon. For example, a method may comprise: synthesizing an OGN-doped novolac polymer, wherein an amount of OGN and/or an oxygen content of the OGN used in the synthesizing is based on a correlation between (a) the amount of OGN and/or the oxygen content of the OGN and (b) at least one property of a resultant graphitized carbon; and carbonizing and graphitizing the OGN-doped novolac polymer to yield a graphitized carbon.

Abstract: An elevated target amount of electrolyte is used to initially fill a molten carbonate fuel cell that is operated under carbon capture conditions. The increased target electrolyte fill level can be achieved in part by adding additional electrolyte to the cathode collector prior to start of operation. The increased target electrolyte fill level can provide improved fuel cell performance and lifetime when operating a molten carbonate fuel cell at high current density with a low-CO2 content cathode input stream and/or when operating a molten carbonate fuel cell at high CO2 utilization.

Abstract: Provided are marine fuel compositions having acceptable wax behavior. In one form, the marine fuel composition has the following enumerated properties: a kinematic viscosity at 50° C. of about 5 cSt to about 700 cSt; a wax endpoint temperature of less than about 100° C.; and a ratio of kinematic viscosity at 100° C. to operating viscosity greater than 1, wherein the operating viscosity is at least about 2 cSt. The marine fuel composition exists in a liquid phase with essentially all the wax in the composition melted (essentially free of solid wax) prior to fuel injection into a marine engine.

Abstract: A methodology using an interwell connectivity model for hydrocarbon management is disclosed. The interwell connectivity model may include interwell connectivity metrics indicative of fluid interconnectivity amongst pairs of wells and may be used as predictive or prescriptive for enhanced oil recovery (EOR). As predictive, the interwell connectivity model may be used to determine an effect of gas injection into the reservoir on one or more aspects of EOR, such as reservoir pressure or production rates. As prescriptive, the interwell connectivity model may be used to improve or optimize various stages of EOR, such as during drilling or construction of the extraction site, during primary depletion, or during one or more huff-and-puff cycles.

Abstract: Systems and methods are provided for operating a combined cycle power plant while enhancing the CO2 content of the flue gas generated by the power plant. The CO2 content is enhanced by using a combination of exhaust gas recycle and oxygen-enriched combustion. The oxygen-containing flow for performing the oxygen-enriched combustion can be generated by an integrated pressure swing adsorption process that allows for production of a commercial grade nitrogen stream (95 vol % or more of N2) while also providing an oxygen-containing stream with an oxygen content between 25 vol % and 48 vol % with high 02 recovery.

Abstract: Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve performing dampening for fluctuations in the streams conducted away from the adsorbent bed unit. The process may be utilized for swing adsorption processes, such as rapid cycle TSA and/or rapid cycle PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.
