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.

Abrégé
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.

The present invention provides a method for estimating hydrocarbon saturation of a hydrocarbon-bearing rock from a measurement for an electrical property a resistivity log and a rock image. The image is segmented to represent either a pore space or solid material in the rock. An image porosity is estimated from the segmented image, and a corrected porosity is determined to account for the sub-resolution porosity missing in the image of the rock. A corrected saturation exponent of the rock is determined from the image porosity and the corrected porosity and is used to estimate the hydrocarbon saturation. A backpropagation-enabled trained model can be used to segment the image. A backpropagation-enabled method can be used to estimate the hydrocarbon saturation using an image selected from a series of 2D projection images, 3D reconstructed images and combinations thereof.

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).

CALIBRATING DIRECT FLOW SIMULATIONS OF ROCK SAMPLES
A method for calibrating a direct flow simulation of a rock sample involves providing a 3D image of a rock sample and generating a segmented structural image of the rock sample from the 3D image by selecting voxels to represent either a pore space or a solid material. Fluid flow is simulated on the segmented structural image with a direct flow simulation. A 3D spatially-resolved fluid velocity map is generated for one or more fluid phases at a pore-scale resolution using pulsed field gradient nuclear magnetic resonance imaging. The simulated fluid flow and the 3D spatially-resolved fluid velocity map are compared to calibrate the direct flow simulation across the rock sample.

A method involving automated salt body boundary interpretation employs multiple sequential supervised machine learning models which have been trained using training data. The training data may consist of pairs of seismic data and labels as determined by human interpretation. The machine learning models are deep learning models, and each of the deep learning models is aimed to address a specific challenge in the salt body boundary detection. The proposed approach consists of application of an ensemble of deep learning models applied sequentially, wherein each model is trained to address a specific challenge. In one example an initial salt boundary inference as generated by a first trained first deep learning model is subject to a trained refinement deep learning model for false positives removal.

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.

Abrégé
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. The shaped charges are simultaneously detonated, whereby pressure waves from neighboring shaped charges interact to cause the additional dents.

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.
