Abstract: A method of the present disclosure for fracturing a subterranean formation (e.g., an unconventional formation) may include: injecting a fracturing fluid into the subterranean formation at a pressure sufficient to hydraulically fracture the subterranean formation. Said fracturing fluid may comprise an aqueous fluid and a zwitterionic surfactant at a concentration of less than or equal to a critical micelle concentration.

Abstract: Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental CO2 emissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental CO2 emissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds

Abstract: An isomerization catalyst is provided, along with corresponding systems and methods, which provides improved isomerization for bio-derived feeds in reaction environments where by-products from deoxygenation are present. The catalyst provides unexpectedly increased activity and/or selectivity in situations where, for example, a deoxygenation effluent is cascaded to the isomerization catalyst. Additionally, the isomerization catalyst can assist with reducing or minimizing hydrogen consumption during isomerization. The increased activity, stability, and/or reduced hydrogen consumption is achieved in part based on using a dispersion agent when adding base metals to the catalyst. In addition to the base metals, the catalyst includes a zeolitic framework structure suitable for isomerization.

Abstract: Isotropic pitch compositions may be obtained by reacting an aromatic feedstock comprising one or more aromatic classes with formaldehyde or paraformaldehyde under acidic conditions. Isotropic pitch compositions may comprise: at least two monomers linked with at least one methylene bridge between each one of the at least two monomers, wherein each one of the at least monomers comprises one or more aromatic classes comprising one or more 5-membered rings, 6-membered rings, and any combination thereof; and wherein the isotropic pitch composition has a weight average molecular weight (Mw) of about 300 g/mol to about 1,500 g/mol, a softening point (Tsp) of 90° C. or greater, and a micro carbon residue (MCR) of about 18 wt % or greater, based on the total weight of the isotropic pitch composition.

Abstract: A method of measuring a pressure of a fluid adjacent a wall of a pipe or vessel. A transducer is attached to the wall of the pipe or vessel. A signal is transmitted by the transducer at a characteristic frequency via a plurality of guided wave modes. The characteristic frequency is a frequency at which the guided wave modes are separated in time from each other when received. The signal is received after the plurality of guided wave modes travel in or through the wall a predetermined number of times. The signal has a signal receipt time after the predetermined number of times. The pressure of the fluid is calculated using the signal receipt time.

Abstract: Herein disclosed are methods and systems related to processes for managing power consumption by a plurality of wells in a hydrocarbon field. The plurality of wells are used to extract hydrocarbons from the field. An exemplary process comprises gathering operating information about conditions in the hydrocarbon field. The process further comprises receiving requests to operate from each of the plurality of wells. The requests to operate include a readiness indicator that provides a readiness state. The process further comprises evaluating the requests to operate based on the operating information and the readiness state of each of the wells. The requests to operate are responded to in order to control power consumption by the plurality of wells.

Abstract: Methods for utilizing and regenerating solvent mixtures for dissolving elemental sulfur within hydrocarbon wells are described herein. One method includes providing a solvent mixture including an elemental sulfur solvent fraction including disulfide compound(s), as well as an odorant fraction including a lactate ester solvent. The method also includes injecting the solvent mixture into a hydrocarbon well such that the elemental sulfur solvent fraction dissolves elemental sulfur deposited on well components, as well as collecting the resulting spent solvent mixture, which includes thiols and residual lactate ester solvent, within a spent solvent separator. The method further includes sparging the spent solvent mixture with oxidizer within the spent solvent separator to allow for oxidation of the thiols to produce the disulfide compound(s) using the residual lactate ester solvent (and, optionally, additional lactate ester solvent), as well as regenerating the solvent mixture using at least a portion of the produced disulfide compound(s).
