摘要： Aspects of the technology described herein identify geologic features within seismic data using modern computer analysis. An initial step is the development of training data for the machine classifier. The training data comprises an image of seismic data paired with a label identifying points of interest that the classifier should identify within raw data. Once the training data is generated, a classifier can be trained to identify areas of interest in unlabeled seismic images. The classifier can take the form of a deep neural network, such as a U-net. Aspects of the technology described herein utilize a deep neural network architecture that is optimized to detect broad and flat features in seismic images that may go undetected by typical neural networks in use. The architecture can include a group of layers that perform aspect ratio compression and simultaneous comparison of images across multiple aspect ratio scales.

摘要： A continuous thermal hydrogen compression system, and methods of thermally compressing hydrogen, are disclosed. A hydrogenation module accepts a hydrogen gas stream to be absorbed or adsorbed to a lean carrier stream through heat removal, thereby producing a heat output and a rich carrier stream containing absorbed or adsorbed hydrogen. A pump, connected to an output of the hydrogenation module, increases the pressure of the rich carrier stream to produce a pressurized rich carrier stream. A dehydrogenation module separates, via an addition of heat, a pressurized hydrogen gas stream from the pressurized rich carrier stream to produce a lean carrier stream. A pressure reducing device reduces the pressure of the lean carrier stream before it is returned to the hydrogenation module. The carrier stream is cycled continuously between the hydrogenation module and the dehydrogenation module.

摘要： A computer-implemented method for analyzing geophysical data is disclosed. Interpretation of geophysical data, such as seismic data, can be performed in multiple stages, such as at an information extraction stage and an information analysis stage. Typically, the information analysis stage is performed by geologists or interpreters, which may be laborious and inconsistent. The disclosed method includes using an information extractor that extracts information indicative of geo-features in a subsurface and an inference engine that analyzes the information indicative of geo-features in a subsurface to generate an output, with the information extractor and the inference engine being integrated and acting in combination. For example, the information extractor may generate summaries of the geo-features or answers to questions. In this way, the information extractor and the inference engine in combination may act synergistically, such as in the context of reasoning, natural language processing, and the outputs generated.

摘要： Geologic modeling methods and systems disclosed herein employ fault face parameterization to constrain and improve the transformation of a faulted physical space geologic model into an unfaulted depositional space geologic model. An illustrative embodiment includes: associating a seismic image with each face of at least one fault in a subsurface region; determining a correspondence map between the seismic images for said at least one fault; parameterizing the faces using the correspondence map to match parameter value assignments for corresponding portions of the faces; creating a displacement map that draws together matching parameter values to align the corresponding portions of the faces; applying the displacement map to the geologic model to create a design space model; modifying the design space model; applying the displacement map in reverse to the modified design space model to obtain a modified geologic model; and outputting the modified geologic model.

摘要： Methods include providing a natural gas stream; directing a first fraction of the natural gas stream to a bioreactor including a propagating culture of hydrocarbon degrading microbes; directing a second fraction of the gas stream to a local power generator and converting the natural gas stream to electricity and heat; using a dynamic control system to balance of the gas stream to the first fraction and the second fraction based on one or more of the availability of electricity from an electricity grid and the price of electricity from the electricity grid; powering, at least in part, the bioreactor with the electricity generated by the local power generator; and harvesting the hydrocarbon degrading microbes from the bioreactor as a biomass. Related systems are also provided.

摘要： Methods and systems for measuring cluster efficiency for stages of wellbores are provided herein. One method includes selecting a frequency band for generating broadband tube waves within the fluid column of the wellbore and generating the broadband tube waves within the fluid column of the wellbore using a pressure pulse generator that is hydraulically coupled to the wellbore. The method also includes recording data corresponding to the broadband tube waves and reflected broadband tube waves using pressure receivers that are hydraulically coupled to the wellbore. The pressure receivers are arranged into arrays with two or more pressure receivers in each array. The data recorded by the pressure receivers relate to characteristics of reflectors (including perforation cluster/fracture interfaces) within the wellbore. The method further includes processing the recorded data using interferometry and performing full waveform inversion(s) on the processed data to determine frequency-dependent, complex-valued reflection coefficients at each perforation cluster/fracture interface.

摘要： Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of resin-coated petroleum coke (referred to as resin-coated petroleum coke proppant particulates). In some instances, the resin-coated petroleum coke proppant particulates have a particle density of equal to or less than about 1.7 grams per cubic centimeter and better resistance to creating fines when exposed to uniaxial stress.

摘要： Methods for completing hydrocarbon wells using variable rate fracturing are provided herein. One method includes positioning a perforation device within a tubular conduit of a downhole tubular, where the downhole tubular extends within a wellbore, and where the wellbore extends within a subsurface region, as well as perforating the downhole tubular using the perforation device to define perforations within the downhole tubular. The method also includes pumping a slurry including fracturing fluid and a lightweight proppant into the tubular conduit according to a variable pumping rate schedule to fracture zones of the subsurface region that are proximate to the perforations, forming corresponding fractures within the subsurface region. The method further includes flowing the slurry into the fractures, via the perforations, to prop the fractures with the lightweight proppant, where the lightweight proppant includes granules formed from a polyolefin, petroleum coke, and/or a polyaromatic hydrocarbon resin.

摘要： A device and method for weld root hardening determination compensated for variations in distance between sensor and sample are disclosed. A sensor is used to determine hardness of a weld for weld fabrication quality control. Because of irregular weld protrusion geometry, there may be variations in the tip of the sensor and the surface, resulting in inconsistent measurements. To compensate, one or both of a positional compensation or a software compensation are performed. Positional compensation mechanically moves the tip of the sensor to within a predetermined range of the surface. Software compensation may at least partly compensate for the variation by using one part of the generated sensor data (such as the 1st harmonic signal) in order to modify another part of the generated sensor data (such as the 3rd harmonic signal). In this way, the sensor determination of hardness of the weld may be less dependent on the variations.
