Abstract: Catalytic compositions and sequential catalytic methods are generally described. In some embodiments, a composition comprises a first catalyst comprising a Cu-modified zeolite, and a second catalyst capable of a coupling reaction between (a) an intermediate resulting from a reaction of a reactant at the first catalyst, and (b) a co-reagent, wherein a rate of diffusion of the co-reagent within one or more cages and/or pores of the first catalyst is lower than a rate of diffusion of the intermediate within the one or more cages and/or pores of the first catalyst.

Abstract: An autonomous surface vessel includes an elongate body, and a sampling system operatively coupled to the body and including one or more sampling modules, wherein each sampling module includes a housing including a storage container, a sampling material receivable within the storage container, an actuation system operatively coupled to the sampling material via a lead line, and an end cap operatively coupled to the lead line and matable with an open end of the storage container. A computer system is in communication with the sampling system to operate the actuation system, wherein each sampling module is actuatable between a stowed state, where the sampling material is received within the storage container and the end cap sealingly engages the open end, and a deployed state, where the end cap is disengaged from the open end and the sampling material is drawn out of the sampling container.

Abstract: Processes for removing deposits from a pump-around loop or simply loop. The process can include isolating a first and a second end of the loop in fluid communication with a vessel to provide an isolated section. The isolated section can include a first conduit disposed within a convection section of a steam cracking furnace or a heat exchanger that is external to the steam cracking furnace that can include char therein. The first end can be connected to an aqueous fluid/oxidant source. The second end can be connected to a second conduit disposed within the convection section. An aqueous fluid/oxidant mixture can be introduced into the first end that can be heated by flowing through the isolated section. The heated mixture can flow through the second conduit to produce a second heated mixture that can be introduced into a radiant section of the steam cracking furnace.

Abstract: Provided herein are methods of making metal-organic frameworks comprising forming a suspension capable of producing metal-organic frameworks; inducing flocculation of the suspension to form a plurality of flocs; allowing the flocs to separate from the suspension and produce a solid phase comprising metal-organic frameworks and a supernatant liquid phase; separating the solid phase from the supernatant liquid phase; and recovering the metal-organic frameworks from the solid phase. The present methods include dissolving a metal salt and at least one ligand in a solvent to form the suspension.

Abstract: A computer-implemented method for integrating a full wavefield inversion (FWI) solution with a non-FWI solution. Computational costs for generating a large bandwidth FWI solution, such as to 50 Hz, may be considerable. However, limiting the FWI solution to a narrower frequency band, such as up to 20 Hz, renders the FWI solution less useful. To remedy this, an FWI solution that is band limited, such as up to 20 Hz, is integrated with a non-FWI solution. The non-FWI solution may comprise seismic stacks or non-seismic data, and is directed to a different frequency band, with at least part of the non-FWI solution frequency band being greater than 20 Hz. In this way, bandwidth extension may be performed for at least one subsurface physical property parameter by combining a band limited FWI solution with a non-FWI solution.

Abstract: A method for determining propped fracture dimensions for a parent well includes hydraulic fracturing a stage of a child well to form a child well fracture, as well as, during the hydraulic fracturing process, measuring, via the parent well, data that are indicative of the formation of a hydraulic connection between the wells via interaction between the wetted front of the child well fracture and the propped region of a corresponding parent well fracture. The method includes measuring TFR (or VFR) data corresponding to the formation of the hydraulic connection between the two wells. The method includes estimating a child well fracture dimension when the hydraulic connection was formed using the TFR data, in combination with a fracture growth profile, and estimating a propped fracture dimension of the parent well fracture based on the estimated dimension of the child well fracture and the distance between the wells at that stage.

Abstract: Systems and a method for resisting a fluctuation in a value of a parameter relating to well equipment using a magnetorheological dampener system are described herein. The method includes continuously determining the value of the parameter relating to the well equipment, determining a fluctuation in the value of the parameter, and comparing the fluctuation in the value of the parameter to a preset limit. The method also includes energizing an electromagnet to increase a viscosity of a magnetorheological fluid (MRF) if the fluctuation exceeds the preset limit.

Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated via at least two binding sites to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. The multidentate organic ligand may comprise a reaction product of a vicinal dicarbonyl compound and an amine-substituted salicylic acid to define the first, second and third binding sites. Particular MOFs may comprise 5,59′-(((1E,2E)-ethane-1,2-diylidene)bis-(azaneylylidene))bis(2-hydroxybenzoic acid) as a multidentate organic ligand.

The hydrocarbon well includes a wellbore that extends within a subsurface region and a downhole tubular that extends within the wellbore and defines a tubular conduit. The hydrocarbon well also includes a number of perforations formed within the downhole tubular and a number of fractures formed within the subsurface region proximate to the perforations. The hydrocarbon well furthers include the proppant positioned within at least a portion of the fractures. The proppant includes a number of polyolefin-coke composite granules, where a characteristic dimension of each polyolefin-coke composite granule is at least 50 micrometers (μm) and at most 3 millimeters (mm), and where each polyolefin-coke composite granule includes a number of polyolefin polymer chains and at least one petroleum coke granule.
