Abstract

Systems and methods include a computer-implemented method for determining and storing a length scale dimension in spatial coordinate systems. A mapping of three-dimensional (3D) grid locations (x, y, z) relative to a continuous surface of the Earth is determined. The 3D grid locations have a grid point spacing in an (x, y) space defining map view coordinates of the continuous surface independent of an elevation z. A length scale (l) is determined for each 3D location. The length scale defines a 3D distance between 3D grid locations, and also defines a structural or geometrical length scale at the 3D location relevant to a given task. Then, (x, y, z, l) information is stored for each 3D grid location. The (x, y, z, l) information defines, for each (x, y) coordinate, a z-coordinate defining an elevation of the continuous surface at the (x, y) coordinate and the local length scale at the (x, y, z) coordinate.

Abstract

An exhaust gas purifying system (100) for an engine (102) includes a three-way catalyst (106), a particulate filter (108), an ammonia sorbent unit (110), an exhaust gas purifying catalyst unit (114), and a gas injection component (112) including an oxygen-containing gas, all coupled to an exhaust line (104). Methods for purifying exhaust gas from an engine (102) include exposing the exhaust gas to a three-way catalyst (106) and a particulate filter (108), thus generating ammonia. The ammonia may be stored in an ammonia sorbent unit (110) during a cold start condition. An oxygen-containing gas may be injected into the exhaust line (104). Once the ammonia sorbent (110) has reached a desorption temperature, the ammonia may be released into the exhaust line (104) and exposed to an exhaust gas purifying catalyst unit (114). The exhaust gas purifying catalyst (114) partially oxidizes the ammonia to nitrous oxides (NOx) and subsequently catalyzes a reaction between the remaining ammonia and the nitrous oxides to give nitrogen gas and water.

Abstract

Systems and methods include a computer-implemented method for optimizing variogram ranges uncertainties. Variogram modeling is performed using variogram models on wells in parallel (major), normal (minor), and vertical directions for continuous log porosity to select a best-fit variogram model using large uncertainty ranges and a preferred-normal distribution. A distribution of geological properties is determined onto the best-fit variogram model. Multiple realizations are executed to determine predicted porosities over the best-fit variogram model. Correlation coefficients of actual porosity versus predicted porosity are generated using the multiple realizations. The process is repeated until a correlation meets a predetermined acceptance criteria. A variogram range for the best-fit variogram model is optimized using a high correlation realization. Correlations are determined for the subset of wells by executing multiple realizations using a same seed number. Final optimized variogram ranges uncertainties are determined by repeating the optimizing and determining until an acceptance correlation is achieved.

Abstract

Systems and methods include a computer-implemented method for determining normalized apparent power. Drilling acoustic signals corresponding to a time domain and generated during drilling of a well. A fast Fourier transformation (FFT) is performed using the drilling acoustic signals to generate FFT data. Normalized FFT data is generated using normalization parameters and a drill string rotation rate record of a drill string used to drill the well. The drill string rotation rate is received during drilling. Normalized apparent power is determined from data points of a predetermined top percentage of the normalized FFT data within a lithological significant frequency range. The normalized apparent power is a measure of the power of the drilling acoustic signals and it is a function of the amplitude and frequency of the normalized FFT data. The lithological significant frequency range is a frequency range within which the drill sounds are more closely related with lithology.

Abstract

Methods for utilizing a supercritical water unit to convert waste plastics to product through hydrothermal treatment in a supercritical unit are provided. Waste plastic is treated in a pretreatment unit, melting the plastic into a liquid and prepares the plastic for the supercritical water unit. The pretreatment unit can dehalogenate the waste plastic. The molten plastic is introduced into a supercritical water unit with water, which generates a product. A flushing stream of product and steam or water from the supercritical water unit is recycled from the supercritical water unit into the pretreatment unit, preheating and pretreating the waste plastic, and acting as a catalyst in the dechlorination reaction. A purge stream removes the products of the dehalogentation reaction occurring in the melting section.

Abstract

Methods for determining sensor channel location in distributed sensing of fiber-optic cables are disclosed. In one method, three or more Fiber Bragg-Gratings (FBGs) connected in series by a standard telecommunication fiber and interrogated using an input distributed fiber-optic sensing (DFOS) laser, where the input DFOS laser has a single wavelength. The input DFOS laser operates on a single wavelength that is different than the respective wavelengths of each of the three or more FBGs. The three or more FBGs are interrogated using an input broadband FBG laser. Each FBG reflects a wavelength of laser light that is proportional to the grating size, using an optical time domain reflectometer (OTDR) at the FBG wavelength, the distance to the particular FBG in the optical domain is computed and compared to the physical measurement of the FBG location. The sensor channel locations of the DFOS system are calibrated and constrained using this method.

Provided herein are methods and systems for treating a tail gas of a Claus process to remove sulfur-containing compounds. The method includes combusting a tail gas of a Claus process in an excess of oxygen gas to yield a thermal oxidizer effluent. The thermal oxidizer effluent includes sulfur dioxide, water vapor, and oxygen. The effluent is routed to a quench tower and contacted with a dilute aqueous acid quench stream to yield sulfurous acid, hydrated sulfur dioxide, or both. The sulfurous acid or hydrated sulfur dioxide is oxidized with the excess oxygen from the thermal oxidizer effluent to yield sulfuric acid.

Abstract

A single well chemical tracer composition comprising core/shell tracer particles and an aqueous fluid is provided. The core/shell tracer particles 102 have a core 106 and a polymer shell 104. At least two tracer chemicals are encapsulated in the core/shell tracer particles. A method of determining residual oil in a reservoir is also provided. The method includes introducing a tracer fluid having the core/shell tracer particles into a wellbore. The reservoir is then maintained for a period of time such that the core/shell particle is ruptured, and the tracer chemicals are released into the reservoir. Then, the method includes producing a produced fluid from the reservoir, measuring the quantity of the tracer chemicals in the produced fluid, and determining a residual oil content of the reservoir based on the measured quantity of the tracer chemicals in the produced fluid.
