Abstract: A method and apparatus are provided for determining movement of a fluid into or out of a subsurface wellbore, to thereby enable accurate allocation of fluids being produced by or injected into each of several zones of the wellbore. A temperature change is effected in the fluid in a semi-continuous or pulsed manner at one or more locations in the wellbore. A temperature of the fluid is measured at one or more sensing locations downstream of the location of the temperature change. A time of flight model is used to determine, for a plurality of points of interest, a fluid flow direction, bulk flow rate and/or a cumulative flow rate contribution.

Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

Abstract: An upgraded crude composition is provided, along with systems and methods for making such a composition. The upgraded crude composition can include an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the upgraded crude composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.

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.
