Abstract

A method for inferring a well integrity criterion used for a CO2 storage site risk assessment of a subterranean formation uses a training well data set having a set of associated training labels. A backpropagation-enabled process is dependency-trained to identify contextual relationships between elements of the training well data set. The dependency-trained backpropagation-enabled process is label-trained using the training well data set and the associated training labels to assess a training well integrity criterion. The label-trained backpropagation-enabled process is used to compute a well integrity criterion in a non-training well data set.

Abstract

A method for determining a relative permeability of a porous medium uses a segmented structural image generated from a 3D image to produce a pore-scale output from a pore-scale flow simulation. A Darcy-scale flow model is generated by simulating fluid flow on boundary conditions of the pore-scale flow simulation and an initial relative permeability model. The Darcy-scale output is compared to the pore-scale output to determine a degree of match. The initial relative permeability model is updated and the Darcy-scale simulation and inverse modeling steps are repeated until the degree of match falls within a pre-determined tolerance.

Abstract

The present invention provides a method for estimating a total porosity of rock from a 3D image. The image is segmented to identify primary and secondary porosity. For primary porosity, segmentation identifies resolved pores and solid material having dimensions greater than or equal to voxel size. For secondary porosity, the impact of partial pores having a dimension less than voxel size and/or porous materials are determined. An image porosity based on the resolved pores of the segmented image is determined and a non-wetting liquid capillary pressure curve produced for calculating a resolved porosity correction factor. Secondary porosity system corrections are determined using a partial pore porosity correction factor and/or a porous matrix correction factor from a volume fraction of partial pores and/or porous material, respectively, identified in the segmented image. Saturation is calculated using the image porosity, the resolved porosity correction factor, and the secondary porosity correction factor(s).

Abstract

A process for the production of glycol from a saccharide-containing feedstock involves catalytically converting the saccharide-containing feedstock in the presence of a heterogenous hydrogenation catalyst and a homogeneous retro-aldol catalyst resulting in a glycol product. Effluent from the conversion zone is contacted with an ion exchange material to adsorb transition metal anions from the retro-aldol catalyst present in the effluent. Adsorbed transition metal anions are then desorbed from the ion exchange material and recycled to the conversion zone. After the contacting step, the effluent is separated into a product stream and a heavies fraction. The product stream is passed to a glycol recovery zone for recovering a purified glycol product.

Abstract

An energetics tool is inserted downhole in a wellbore tubular, which has a string of at least two axially separated shaped charges. With this tool N axially separated circumferential dents are created, using a string of only M = (N+1)/2 axially separated charges. N is an odd number of 3 or higher. Two additional axially separated dents may be created for each additional axially separated shaped charge that is added to the string. For example, by simultaneously detonating two shaped charges, it is possible to create three axially separated dents. By simultaneously detonating three shaped charges that are axially separated from each other, it is possible to create five axially separated dents. The shaped charges are contained in charge housings that are mechanically interconnected with a longitudinal connecting rod.

Abstract

A computer-implemented approach has been developed to estimate corrosion rate (100) in a section of a pipe transmitting a corrosive substance. A trained surrogate model (60) is provided to output an estimated value of maximum near-wall velocity (70) of the substance in the pipe section. The estimated value of maximum near-wall velocity (70) is then fed into a computerized electrochemical model (80), together with electrochemical parameters (90) associated with the corrosive substance, which electrochemical model then determines an estimated corrosion rate (100) imposed on the pipe section by the corrosive substance. The surrogate model is trained using results of a full physics-based simulation. Once it has been trained, the surrogate model can generate the estimated value of maximum near-wall velocity (70) much faster than the full physics-based simulation can.

Abstract

A method for capturing long-range dependencies in geophysical data sets involves dependency-training a first b ackpropagation-enabled process, followed by interdependency-training the dependency-trained backpropagation-enabled process. Dependency-training computes spatial relationships for each input channel of a geophysical data set. Interdependency -training computes inter-feature and spatial relationships between each of the featurized input channels. The output conditional featurized input channels are fused to produce a combined representation of the conditional featurized input channels. The combined representation is inputted to a second backpropagation-enabled process to compute a prediction selected from the group consisting of a geologic feature occurrence, a geophysical property occurrence, a hydrocarbon occurrence, an attribute of subsurface data, and combinations thereof.

Abstract

A process for improving yield of kerosene from a renewable feedstock involves directing a hydroprocessed liquid stream to a lead stripper to separate a lead stripper bottoms stream and a lead stripper overhead stream comprising naphtha, lower and higher boiling point range hydrocarbons and water. Bulk water is removed from the lead stripper overhead stream resulting in an unstabilized hydrocarbon stream, which is passed to a stabilization column to separate a stabilized naphtha-containing stream from the lower boiling point range hydrocarbons. The stabilized naphtha-containing stream is passed to a rectification column to separate a rectification bottoms stream and a naphtha product stream. Kerosene and diesel boiling range product streams are separated from the lead stripper bottoms stream in a vacuum fractionator.

Abstract

A process for producing kerosene involves reacting a renewable feedstock in a hydroprocessing section under hydroprocessing conditions sufficient to cause a hydroprocessing reaction to produce a hydroprocessed effluent. The hydroprocessed effluent is separated to produce a hydroprocessed liquid stream and a separation system offgas stream. The hydroprocessed liquid stream is directed to a work-up section where gases are stripped to produce a stripped liquid product stream and a stripper offgas stream. A gas stream comprising the separation system offgas stream and/or the stripper offgas stream are directed to a gas-handling section to obtain a pressurized gas stream and a hydrocarbon fraction that is liquid at a pressure in a range from 0 - 1.5 MPaG and a temperature in a range from 0 to 50C. The hydrocarbon fraction is recycled to the work-up section. A kerosene stream separated in the product recovery unit has a higher yield compared to conventional processes.

Abstract

A method for capturing long-range dependencies in seismic images involves dependency-training a backpropagation-enabled process, followed by label-training the dependency-trained backpropagation-enabled process. Dependency-training computes spatial relationships between elements of the training seismic data set. Label-training computes a prediction selected from an occurrence, a value of an attribute, and combinations thereof. The label-trained backpropagation-enabled process is used to capture long-range dependencies in a non-training seismic data set by computing a prediction selected from the group consisting of a geologic feature occurrence, a geophysical property occurrence, a hydrocarbon occurrence, an attribute of subsurface data, and combinations thereof.
