Abstract: Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of agitated petroleum coke particles (referred to as agitated petroleum coke proppant particulates). In some instances, the agitated petroleum coke proppant particulates are characterized by a particle density of equal to or less than about 1.6 grams per cubic centimeter. The agitation processing of the present disclosure can remove petroleum coke particles having initiated cracking or scissions that are prone to fines production.

Abstract: A drive system for liquefied natural gas (LNG) refrigeration compressors in a LNG liquefaction plant. Each of three refrigeration compression strings include refrigeration compressors and a multi-shaft gas turbine capable of non-synchronous operation. The multi-shaft gas turbine is operationally connected to the refrigeration compressors and is configured to drive the one or more refrigeration compressors. The multi-shaft gas turbine uses its inherent speed turndown range to start the one or more refrigeration compressors from rest, bring the one or more refrigeration compressors up to an operating rotational speed, and adjust compressor operating points to maximize efficiency of the one or more refrigeration compressors, without assistance from electrical motors with drive-through capability and variable frequency drives.

Abstract: Sulfur-crosslinked olefins, particularly sulfur-crosslinked heavy hydrocarbon products having one or more sulfur-crosslinked olefin moieties, may undergo pyrolysis to form sulfur-doped porous carbon having high BET surface area values. Pyrolysis to form the sulfur-doped porous carbon may be particularly efficacious in the presence of a hydroxide base. BET surface areas up to 2000 m2/g or even higher may be obtained. Such sulfur-doped porous carbon may be prepared by combining a heavy hydrocarbon product with sulfur, heating to a first temperature state to form a liquefied reaction mixture containing a sulfur-crosslinked heavy hydrocarbon, homogeneously mixing a hydroxide base with the liquefied reaction mixture, and pyrolyzing the sulfur-crosslinked heavy hydrocarbon to form sulfur-doped porous carbon.

Abstract: Systems and methods are provided for handling sequence-dependent data as part of processing and/or analyzing large data sets in a distributed data processing environment. The distributed data processing environment can be suitable for handling data generated at a plurality of sites within a network of manufacturing sites. The systems and methods can allow for pre-processing of some values for sequence-dependent data. This can allow secondary aggregated values and/or secondary aggregated data sets to be generated from sequence-dependent data that can span multiple blocks or partitions. Pre-calculation of secondary aggregated values and/or secondary aggregated data sets for sequence-dependent data can allow the efficiencies of parallel or distributed computation to be at least partially retained while also allowing for desired processing of the sequence-dependent data.

Abstract: A method for estimating a flow rate of a material (e.g., a multiphase fluid) may include: flowing the material through one or more of a plurality of receptacles of a dielectric contrast analysis structure that includes: a bulk dielectric substance and the plurality of receptacles in the bulk dielectric substance; exposing the dielectric contrast analysis structure to incident electromagnetic radiation; detecting and analyzing a resultant electromagnetic radiation from the exposed dielectric contrast analysis structure to yield a phase fraction in the material and a phase distribution in the material; measuring a differential pressure across the dielectric contrast analysis structure; and estimating the flow rate of the material using the differential pressure, the phase fraction, and the phase distribution in the material.

Abstract: A method for collecting data relating to characteristics of a wellbore by generating tube waves within the wellbore using an electro-hydraulic discharge (EHD) source includes generating tube waves that propagate within a fluid column of a wellbore using an EHD source, where the fluid column is defined by a casing string within the wellbore. The method also includes allowing at least a portion of the generated tube waves to interact with acoustic impedance boundaries that act as reflectors within the wellbore, creating reflected tube waves that propagate within the fluid column. The method further includes recording data corresponding to the generated tube waves and the reflected tube waves using a receiver, where the recorded data relate to characteristics of the reflectors within the wellbore.

Abstract: A jet boiling range composition is provided with an unexpected distribution of carbon chain lengths for the hydrocarbons and paraffins in the composition. The hydrocarbon composition corresponds to a jet boiling range composition that includes 40 wt % or more of hydrocarbons and/or paraffins that have carbon chain lengths of 17 carbons or 18 carbons. Additionally or alternately, the hydrocarbon composition can contain 45 wt % or less of C14-C17 hydrocarbons and/or paraffins. This unexpected distribution of carbon chain lengths in a jet boiling range composition can be achieved for a composition that has a freeze point of −40° C. or lower and a flash point of 38° C. or higher. Optionally, the jet boiling range composition can also have a T10 distillation point of 205° C. or less (such as down to 150° C.) and a final boiling point of 300° C. or less

Abstract: Hydrocarbon wells and methods of probing a subsurface region of the hydrocarbon wells. The hydrocarbon wells include a wellbore, a downhole sensor storage structure, and a detection structure. The wellbore may extend within a subsurface region and between a surface region and a downhole end region. The downhole sensor storage structure is configured to release a flowable sensor into a wellbore fluid that extends within the wellbore, and the flowable sensor may be configured to collect sensor data indicative of at least one property of the subsurface region. The detection structure may be configured to query the flowable sensor to determine the at least one property of the subsurface region. The methods include releasing a flowable sensor, collecting sensor data with the flowable sensor, and querying the flowable sensor.

Abstract: Systems and methods are provided for separation of CO2 from dilute source streams. The systems and methods for the separation can include use of contactors that correspond radial flow adsorbent modules that can allow for efficient contact of CO2-containing gas with adsorbent beds while also facilitating use of heat transfer fluids in the vicinity of the adsorbent beds to reduce or minimize temperature variations. In particular, the radial flow adsorbent beds can be alternated with regions of axial flow heat transfer conduits to provide thermal management. The radial flow structure for the adsorbent beds combined with axial flow conduits for heat transfer fluids can allow for sufficient temperature control to either a) reduce or minimize temperature variations within the adsorbent beds or b) facilitate performing the separation using temperature as a swing variable for controlling the working capacity of the adsorbent.

Abstract: Provided herein are molecular sieve membranes for separating hydrocarbons of a lube feed stock into a permeate and a retentate based on molecular shape. The molecular sieve membranes comprise one or more layers of size-selective catalyst and a porous support comprising a plurality of diffusing gaps. Each layer of size-selective catalyst has a plurality of perpendicular membrane channels and a plurality of opening pores. The porous support is in fluidic communication with the plurality of opening pores to provide a fluidic pathway between the perpendicular membrane channels and the diffusing gaps. Also provided are processes for separating n-paraffins from other hydrocarbons in a lube feed stock using the present molecular sieve membranes.
