Abstract: Methods and devices use improved FWI techniques for seismic exploration of subsurface formations including salt bodies using a travel-time cost function. In calculating the travel-time cost function, time-shifts may be weighted using cross-correlation coefficients of respective time-shifted recorded data and synthetic data generated based on current velocity model. The improved methods enhance the resulting image while avoiding cycle-skipping and issues related to amplitude difference between synthetic and recorded data.

Abstract: A method for predicting mineralogical, textural, petrophysical and/or elastic properties at locations without rock samples based on well log data is provided. The method includes obtaining well log data and values of a target property measured by analyzing rock samples at rock sample locations. The method further includes building and calibrating a prediction model using machine learning algorithms, the well log data and the values of the target property at the rock sample locations. The method then estimates values of the target property at one or more locations without rock samples using the prediction model.

Abstract: Methods for processing seismic data acquired with non-impulsive moving sources are provided. Some methods remove cross-talk noise from the seismic data using emitted signal data and an underground formation's response estimate, which may be iteratively enhanced. Some methods perform resampling before a spatial or a spatio-temporal inversion. Some methods compensate for source's motion during the inversion, and/or are usable for multiple independently moving sources.

Abstract: Methods and systems for processing data acquired using a variable-depth streamer, obtain up-going and down-going wavefields at a predetermined datum, and use them to identify multiples included in the up-going wavefield. An image of a geological formation under the seabed is then generated using the data from which the multiples have been removed, and/or the multiples.

Abstract: A seismic exploration method includes performing a true amplitude PSDM based on an initial velocity model of a subsurface formation to obtain a reflectivity model, and then a Born modeling using the reflectivity model to generate synthetic data. An image-based reflection full waveform inversion is applied to a cost function of differences between seismic data acquired over the subsurface formation and the synthetic data to update the initial velocity model. The updated velocity model enables exploring the presence of and/or assisting in the extraction of natural resources from the subsurface formation.

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.

Abstract: A system for immersion cooling computing system equipment includes a container containing a volume of immersion cooling fluid. At least one heat generating computing system equipment component and a liquid-liquid heat exchanger are disposed in the volume of immersion cooling fluid. A manifold system is disposed between the heat generating computing system equipment component and the liquid-liquid heat exchanger to direct a flow of immersion cooling fluid between the heat generating computing system component and the liquid-liquid heat exchanger and to isolate the flow of immersion cooling fluid from a bulk amount of immersion cooling fluid. The flow of immersion cooling fluid and the bulk amount of immersion cooling fluid constitutes the volume of immersion cooling fluid.

Abstract: Method, source array and source element that generate seismic waves. The source element includes an enclosure having an opening covered by a piston; a local supply accumulator fluidly communicating with an interior of the enclosure, a pressure of the fluid inside the local supply accumulator being larger than a pressure of the fluid inside the enclosure; a local supply valve located between the local supply accumulator and the enclosure and configured to control a flow of the fluid from the local supply accumulator to the interior of the enclosure; and a controller configured to control the local supply valve such that the pressure inside the enclosure does not fall below a first preset value based upon an ambient pressure of the enclosure while seismic waves are generated.
