Abstract: A system for cooling an electronic component includes a cylindrical container, a support, a heat exchanger, and one or more micropumps. The cylindrical container includes an internal volume that stores dielectric liquid. The internal volume is formed by an interior wall and a bottom of the cylindrical container. The support is positioned in the internal volume of the cylindrical container, and retains the electronic component within the dielectric liquid stored in the internal volume of the cylindrical container. The support also controls a flow of the dielectric liquid. The heat exchanger is positioned in the cylindrical container and circulates water from an external environment of the cylindrical container into and out of the internal volume of the cylindrical container. The one or more micropumps are integrally formed with and powered by the electronic component, and circulate the dielectric liquid through the electronic component.

Abstract: A method for imaging a formation of a subsurface includes receiving input data d related to the subsurface, generating synthetic data u related to the subsurface, by applying an implicit finite-difference approach to a reflectivity model r, updating a velocity model V based on the input data d and the synthetic data u, and generating an image of the formation in the subsurface based on the updated velocity model, wherein the formation is used to locate natural resources.

Abstract: A geothermal plant, for extracting energy from a geothermal reservoir located below the ocean bottom, includes a floating platform; a riser that extends from a well drilled into the geothermal reservoir, to the floating platform; an electrical pump having a mechanical actuation part located in a bore of the riser, and an electronic part located outside the riser, wherein the electrical pump is configured to pump a geothermal liquid from the geothermal reservoir to the floating platform; and a power plant located on the floating platform and configured to use a steam produced by the geothermal liquid to generate electrical power. The electrical pump is placed at a depth of the riser where the geothermal liquid is in a single-phase.

Abstract: Computing device, computer instructions and method for processing input seismic data d. The method includes receiving the input seismic data d recorded in a first domain by seismic receivers that are towed in water, the input seismic data d including pressure data and/or and particle motion data; generating a model p in a second domain to describe the input data d; processing the model p to generate an output particle motion dataset; and generating an image of the surveyed subsurface based on the output particle motion dataset.

Abstract: A method for generating an image of a subsurface based on blended seismic data includes receiving the blended seismic data, which is recorded so that plural traces have uncontaminated parts with different uncontaminated recording time lengths, selecting plural subgroups (SG1, SG2) of traces so that each subgroup (SG1) includes only uncontaminated parts that have a same uncontaminated recording time length, processing the traces from each subgroup to generate processed traces, mapping the processed traces to a same sampling, combining the processed traces from the plural subgroups (SG1, SG2) to generate combined processed traces, and generating an image of a structure of the subsurface based on the combined processed traces.

Abstract: Property values inside an explored underground subsurface are determined using hybrid analytic and machine learning. A training dataset representing survey data acquired over the explored underground structure is used to obtain labels via an analytic inversion. A deep neural network model generated using the training dataset and the labels is used to predict property values corresponding to the survey data using the DNN model.

Abstract: Methods and apparatuses for seismic data processing perform a least-squares reverse time migration method in which surface-attribute-independent coefficients for the surface attribute gathers are demigrated to reduce the computational cost.

Abstract: Limitations in accuracy and computing power requirements impeding conventional Kirchhoff migration and reverse time migration are overcome by using the wave-equation Kirchhoff, WEK, technique with Kirchhoff migration. WEK technique includes forward-propagating a low-frequency wavefield from a shot location among pre-defined source locations, calculating an arrival traveltime of a maximum amplitude of the low-frequency wavefield, and applying Kirchhoff migration using the arrival traveltime and the maximum amplitude.

Abstract: Well completion is accomplished by obtaining a sample of geological material from the subsurface and generating primary data for the sample of geological material. The primary data include textural data, chemical data and mineralogical data. The primary data are used to derive secondary data for the sample of geological material, and the primary data and the secondary data are used to generate tertiary data for the sample of geological material. The tertiary data are a quantification of physical characteristics of the sample of geological material. The primary data, secondary data and tertiary data are used to determine a location of a stage along a well and an arrangement of perforation clusters in the stage.
