DOWNHOLE TOOL AND METHOD FOR PERFORATING A DOWNHOLE TUBULAR
A downhole tool, with an elongate tool housing that extends around a central longitudinal tool axis, houses a sting, a press device, and a bending arm. The sting is movable in a radially outward direction. The press device acts on the sting, to force the sting in the radially outward direction upon relative movement of the press device, in longitudinal direction, with respect to the sting whereby the sting may extend outside the tool housing. The sting is mounted on a distal end of the bending arm. At its proximal end the bending arm is longitudinally secured stationary relative to the tool housing. The sting and the distal end of the bending arm are movable in unison in a longitudinal-radial plane from the central longitudinal tool axis. The downhole tool can be used to perforate a wall of a downhole tubular arranged within a borehole in the Earth.

METHOD AND SYSTEM FOR PREDICTING SAND FAILURE IN A HYDROCARBON PRODUCTION WELL AND METHOD AND SYSTEM FOR PRODUCING HYDROCARBON FLUIDS FROM AN EARTH FORMATION
Bottom hole pressure (BHP) actuals and bottom hole temperature (BHT) actuals in a hydrocarbon production well are recorded as a function of time, during production of hydrocarbon fluids. Selective statistical measures of both the BHP actuals and the BHT actuals are determined as a function of time. These selective statistical measures suitably represent estimates of expected normal BHP actuals and BHT actuals in case there is no imminent sand failure, supplemented with an uncertainty measure of the estimates of expected normal BHP and BHT. The BHP actuals and the BHT actuals are compared with respective BHP and BHT anomaly thresholds based on the selective statistical measures. An anomaly alert is automatically issued upon meeting a condition wherein both the BHP actuals and the BHT actuals exceed their respective anomaly threshold. The anomaly alert is an indication of a predicted imminent sand failure of the hydrocarbon production well in operation.

The invention relates to pre-treating an oil derived from a renewable feedstock to remove at least a portion of one or more contaminants by filtering the oil with a nanofiltration membrane. The resulting permeate oil has a reduced concentration of the contaminant relative to the feed stream to the nanofiltration membrane.
A process for hydroprocessing a renewable feedstock in a fixed-bed reactor system having at least one catalytic bed involves directing a downward flow of the renewable feedstock to a filtering zone having top-open interstitial portions to receive the downward flow and top-covered annular portions that are in fluid communication with a headspace between the filtering zone and a catalytic zone. The feedstock flows from the interstitial portions to the annular portions through a filtering material disposed between the interstitial portions and the annular portions, resulting in a filtered feedstock, which then flows to the catalytic zone. In the catalytic zone, filtered feedstock is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetalation, hydrocracking, hydroisomerization, and combinations thereof.

Abrégé
Syngas is produced from hydrocarbons and carbon dioxide. A steam methane reformer is configured to receive a hydrocarbon containing stream and steam, and to produce a first intermediate syngas stream from the hydrocarbon containing stream and the steam. At least a fraction of the hydrogen produced in the steam methane reformer is removed from the first intermediate syngas stream, and fed to a reverse water gas shift reactor in which carbon dioxide is reverse shifted to CO. The resulting CO-containing effluent stream is combined with a second intermediate syngas stream, which is a residue stream from the first intermediate syngas stream from which the fraction of hydrogen has been removed. Unconverted hydrogen which is discharged from the reverse water gas shift reactor, can be reintroduced in the second intermediate syngas stream together with the CO. The combined stream is a final syngas stream.

A method for predicting an occurrence of a geological feature in a geologic thin section image uses a backpropagation-enabled classification process trained by inputting extracted training image fractions having substantially the same absolute horizontal and vertical length and associated labels for classes from a predetermined set of geological features, and iteratively computing a prediction of the probability of occurrence of each of the classes for the extracted training image fractions. The trained backpropagation-enabled classification model is used to predict the occurrence of the classes in extracted fractions of non-training geologic thin section images having substantially the same absolute horizontal and vertical length as the training image fractions.

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.
