Abstract: Thermal imaging may be used for obtaining measurements of a tribological testing apparatus including a contact temperature. For example a method of calculating a contact temperature may include: introducing a testing sample into a contact zone of a tribological testing apparatus; engaging a testing operation of the tribological testing apparatus; measuring a contact emission of a testing surface of the tribological testing apparatus with an infrared camera; and calculating a contact temperature of the testing sample in the contact zone from the contact emission; wherein the tribological testing apparatus has a carbon coating on the testing surface of the contact zone, wherein the carbon coating has a first infrared emissivity, wherein the testing sample has a second infrared emissivity, and wherein the first infrared emissivity is within +/−20% of the second infrared emissivity.

Abstract: Bicomponent carbon fibers may comprise an inner region that is at least partially surrounded by an outer sheath, each comprising at least one carbonized pitch. The inner region comprises 70 wt % or greater mesophase pitch that has been carbonized, and the outer sheath comprises up to 70 wt % mesophase pitch that has been carbonized. An amount of mesophase pitch in the outer sheath is lower than in the inner region. The bicomponent carbon fibers may be formed by extrusion of first and second pitch compositions having the requisite amounts of mesophase pitch, followed by carbonization.

Abstract: A method of full wavefield inversion using simultaneous-source, ocean bottom sensor (OBS) data, including: obtaining, with a computer, simultaneous-source OBS data recorded by receivers in a seismic acquisition; generating, with a computer, synthetic OBS seismic data from a model based on reciprocity; blending, with a computer, the synthetic OBS seismic data; differencing, with a computer, the simultaneous-source OBS data recorded by receivers and the synthetic data to form a pseudo-deblended residual; updating the model based on the pseudo-deblended residual; and prospecting for hydrocarbons at a location derived from the updated model.

Abstract: The present disclosure relates to methods and systems for treating a fluid produced from a biorefinery to remove contaminants, such as metals and sulfur therefrom. Biomass is pyrolysed and activated to form activated carbon used to remove such contaminants. The fluid produced from the biorefinery may be one or more of a biofuel, a biogas, and wastewater.

Abstract: A method for monitor-centric interpretation of offset pressure monitoring measurements includes simultaneously hydraulic fracturing treatment stages corresponding to treatment wells, measuring corresponding pressure data via pressure gauge(s) at monitor well(s), detecting pressure responses corresponding to fracture hits within the pressure data, and determining a reasonable velocity window for when a fracture originating from each treatment stage is likely to affect the pressure data. The method includes detecting treatment stage(s) that are likely to be the origin of each fracture hit based on the reasonable velocity window and, for each fracture hit that only has one likely originating treatment stage, assigning the detected fracture hit to such treatment stage. The method includes determining observation property data corresponding to the treatment stages that have been assigned to the fracture hits and iteratively assigning, based on such data, each unassigned fracture hit to one of the corresponding likely originating treatment stages.

Abstract: A method for producing a deposit resistant fluid includes combining a base stock and one or more additives to form a blended fluid configured to resist forming deposits in an oxidizing environment. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms.

Abstract: In various aspects, systems and methods are provided for operating an oxygen-fired catalyst regenerator with flue gas recycle and CO2 capture. An oxygen-fired catalyst regenerator contrasts with an air-fired regenerator. The oxygen-fired catalyst regenerator substantially reduces nitrogen within the system, which facilitates CO2 capture by reducing the energy required to capture CO2. In various aspects, a first portion of the regenerator flue gas is passed to a CO2 capture system and a second portion is recycled to the regenerator. Before the flue gas is recycled or diverted to the CO2 capture, it is passed to various processes that remove and/or reduce SOx, NOx, particulate, and water content. In various aspects, a portion of the treated flue gas may be combined with substantially pure O2 and recycled to the regenerator.

Abstract: Compositions are provided that include at least a portion of an isoparaffinic blend component, an iso-olefinic blend component, or a combination thereof, along with a method for making such a blend component. The highly isoparaffinic and/or iso-olefinic nature of the blend component can allow a blend component to be used in combination with both conventional/mineral fractions as well as non-traditional feeds to form fuel fractions and/or fuel blending component fractions. Examples of fuels that can be formed by making a blend that includes an isoparaffinic and/or iso-olefinic blend component include diesel fuels, marine gas oils, and various types of marine fuel oils, such as very low sulfur fuel oils.

Abstract: A frozen material prevention system for preventing a freezable material in a fluid flow from freezing and accumulating frozen material in a flow path, including, a surface configured to interact with a freezable-material-miscible (FMM) liquid to retain the FMM liquid to the surface. The system can include the FMM liquid. The FMM liquid can be configured to absorb the freezable material to prevent freezing and accumulation of frozen material on the surface.
