Abstract: A computer program product is embodied on a non-transitory computer readable medium. The computer readable medium has instructions stored thereon that, when executed by a computer, causes the computer to perform receiving image data that is to be recognized by the at least one classifier. The image data captures an occurrence of a fossil species. The computer can also perform generating an output via the at least one classifier based on the received image data. The computer can also perform comparing the output of the at least one classifier with a desired output. The computer can also perform modifying the at least one classifier so that the output of the classifier corresponds to the desired output.

Abstract: A method for drilling a borehole in a subsurface formation includes receiving measured values indicative of operations performed by drilling equipment while drilling. The measured values include hookload values. The hookload values are analyzed to identify hookload values acquired while connecting a drill pipe, and a block weight value is set based on such a hookload value. The block weight value is subtracted from the hookload values to produce rebased hookload values. A rig state model produces a value for a state of the drilling equipment based on the measured values and the rebased hookload values. Responsive to the state of the drilling equipment, an operation performed to drill the subsurface formation is changed.

Abstract: A method of recovering paraxylene in a pressure swing adsorption unit with varying hydrogen purge pressures. The pressure swing adsorption zone is adapted to adsorb and desorb paraxylene based on the cycling of partial pressure in the zone. A first hydrogen purge is fed concurrent to the feed. A second hydrogen purge is countercurrent to the feed.

Abstract: A method for analyzing a rock sample includes segmenting a digital image volume corresponding to the rock sample, to associate voxels in the digital image volume with pore space or solid material. A distance transform is applied to each pore space voxel. The distance transform assigns a distance value to the pore space voxel specifying distance from the pore space voxel to a solid material voxel. Drainage is numerically simulated by, for a pore space, selecting each distance value assigned to a pore space voxel that is greater than a predetermined threshold value to represent a radius of a sphere of a non-wetting fluid introduced into the pore space. The sphere is centered at the pore space voxel corresponding to the distance value. The digital image volume is numerically analyzed to characterize a material property of the rock sample at a non-wetting fluid saturation produced by the drainage.

Abstract: According to one embodiment, there is provided a method of correcting recorded seismic data where each receiver clock is potentially inaccurate. Since the seismic wave field is not random, and contains coherent events that are recorded by all receivers in a local area, it is possible to estimate the differences in the time reference by comparing the recordings of different receivers in a local area. With no external time reference, time signal, or pilot trace, an entire seismic data itself can be used to determine how each receiver's clock is drifting from true time.

Abstract: A method for retrofitting a system for recovering paraxylene. The system is retrofitted with a pressure swing adsorption unit and a second isomerization reactor. The retrofit lowers the variable cost of the plant, while providing the opportunity to maintain existing equipment and furnace and refrigeration duty.

Abstract: A method for recalculating the solvent power of a light oil, SP(LO recalculated), is provided. The method comprises: titrating the light oil against a reference oil, optionally in the presence of a titrant, to determine a volume fraction of the light oil at the onset of asphaltene precipitation, V(onset fraction LO), a volume fraction of the reference oil at the onset of asphaltene precipitation, V(onset fraction RO), and, where a titrant is present, a volume fraction of the titrant at the onset of asphaltene precipitation, V(onset fraction T), and determining the recalculated solvent power of the light oil, SP(LO recalculated), according to the following formula: SP ( LO   recalculated ) = ( CSP ( RO ) - SP ( RO ) * V ( onset   fraction   RO ) - x * SP ( T ) * V ( onset   fraction   T ) ) V ( onset   fraction   LO ) wherein: CSP(RO) is the critical solvent power of the reference oil, SP(RO) is the solvent power of the reference oil, SP(T) is the solvent power of the titrant, and x is 1 where a titrant is present, and otherwise is 0. The recalculated solvent power may be used in methods for preventing asphaltene precipitation during processing of crude oils in a refinery.

Abstract: A method comprises correlating—in a system which comprises a non-aqueous phase comprising a hydrocarbon fluid, and an aqueous phase—partitioning levels of a basic contaminant and/or an acid of interest into the aqueous phase with the pH of the aqueous phase. The partitioning levels of the basic contaminant and the acid of interest, as well as the pH of the aqueous phase, are obtained under conditions which are representative of those used in a partitioning process in which a basic contaminant is removed from a hydrocarbon fluid.
The correlations may be used in a method for selecting an acidic environment for use in a partitioning process, for estimating corrosion risk downstream of a partitioning process, or for controlling a partitioning process.
