Abstract: A method and a system for a multi-task neural network for salt model building is disclosed. Imaging salt in the subsurface may be challenging because salt may be associated with strong diffraction and poor focused image, thereby making it difficult to interpret sediments underneath salt body or near salt flanks. To better image salt in the subsurface, the method and system trains, in combination, multiple aspects related to the subsurface, one of which is the target salt feature, in order to generate a salt feature model. The multiple aspects may include the target salt feature, such as the predicted salt mask, and at least one other salt feature, and one or more subsurface features, such as reconstruction of the input image and P-wave velocity. Thus, the salt model may better image salt, thereby making the seismic migration image more focused and easier to identify geological structures.

Abstract: Methods for analyzing subsurface process data in order to perform one or more subsurface operations in a subsurface are provided. Generating subsurface models is typically a long and laborious process in which subsurface process data is analyzed in order to generate the subsurface models. In contrast, work in generating the subsurface models may be front-loaded by first using a physics simulator in order to generate a training set of subsurface forward models, and then performing machine learning using the training set to generate one or more proxy models, such as a forward proxy model and an inverse proxy model. The machine learning may be constrained using physics-based rules to better converge on the proxy models. In this way, the already-trained inverse proxy model may input the subsurface process data in order to generate potential inverse models, which may then be used to perform subsurface operations in the subsurface.

Abstract: The methods disclosed herein are directed to an automated method for monitoring performance of a well in a hydrocarbon reservoir for continuous monitoring of well test production data for a plurality of well system performance parameters, trending actual performance parameter deviations from a well system model, and determining most probable root cause(s) of the performance parameter deviations based on the trend of the deviations of a plurality of parameters for an outflow component of a well performance model and a plurality of parameters inflow component of a well performance model. The method automatically notifies an operator of detected root causes of the performance degradation, and further may perform corrective action in the well system based on at least one root cause of the deviation determined by the well performance model.

Abstract: A method for deriving at least one pore or fluid relaxation parameter and endpoint selected from the group consisting of a longitudinal T1 pore surface relaxivity constant (ρ1), a transverse T2 pore surface relaxivity constant (ρ2), a pore surface-to-volume ratio (A/V), an equivalent pore-throat radius (req), and a bulk fluid relaxation time (TB) comprising: identifying modes in NMR T1-T2 data; assigning the modes to a poro-fluid class; clustering the modes based on poro-fluid class; estimating TB based on an asymptote fit of the clusters using T1 and T2 relaxation mechanisms in a bulk fluid relaxation-dominated limit; estimating ρ2/ρ1 based on an asymptote fit of the clusters using T1 and T2 relaxation mechanisms in a surface relaxation-dominated limit; fitting the T1 and T2 relaxation mechanisms to the clusters using the estimated TB; and deriving the pore or fluid relaxation parameter and endpoint for the poro-fluid classes from the fit.

Abstract: A process for increasing the softening point of asphalt using an eductor, preheated asphalt is mixed with an input gas in the eductor to form a gas/asphalt mixture. The gas/asphalt mixture is conducted to a heated and pressurized oxidizer vessel via piping connected to the discharge connection of the eductor, where the piping enables a bubble flow pattern to develop therein to enable reaction of the oxygen with the asphalt. The oxygen entrained asphalt mixture is discharged from an exit port of the piping in the oxidizer vessel. The resulting oxidized asphalt product stream has a softening temperature greater than the preheated asphalt feed. The process minimizes the off-gas produced to reduce the carbon footprint.

Abstract: This application relates to production of renewable fuels, including a method of producing renewable fuels. The method comprises hydrotreating a biofeedstock by contacting reactants comprising a combined feedstock and hydrogen with a hydrotreating catalyst to produce normal paraffins. The combined feedstock comprises a biofeedstock and an additional feedstock. The biofeedstock has about 10% or more of each of metals, phosphorous, and chlorophyll than the additional feedstock. The biofeedstock comprises the metals in an amount of about 300 parts per million (“ppm”) or less, the phosphorous in an amount of about 300 ppm or less, and the chlorophyll in an amount of about 50 ppm or less. The method further comprises isomerizing at least a portion of the normal paraffins to produce branched paraffins in an isomerization effluent.

Abstract: Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.

Abstract: Systems and methods are provided for ozonolysis of polycyclic aromatic hydrocarbons (PAHs) in a liquid CO2 reaction environment. It has been unexpectedly discovered that oxygen-containing functional groups can be added to PAH substrates while substantially avoiding combustion reactions and while reducing or minimizing formation of energetic intermediates. Because the formation of energetic intermediates is minimal, the ozonolysis can be performed at temperatures near ambient (e.g., between −10° C. and 50° C.) while still achieving a satisfactory safety profile. In various aspects, ozonolysis can occur while forming a reduced or minimized amount of water, such as forming substantially no water in the reaction environment.
