  • Publication number: 20240345700
    Abstract: The disclosure describes embodiments of systems, methods, and non-transitory computer readable storage media that dynamically surface multiple user-specific application function GUIs for setting up (or accessing) application functions for a user account. For instance, the disclosed systems can select and display a GUI for a first application function from a set of application functions. Moreover, upon receiving user interactions with the GUI for the first application function (and identifying whether or not the first application system is activated for the user account), the disclosed systems can select a second application function from the set of application functions and displays a GUI (e.g., a setup interface) for the second application function from the set of application functions.

  • Publication number: 20230350089
    Abstract: Seismic data is processed using a full-waveform inversion using a model with a pseudo-? layer. The presence of the pseudo-? layer in the model enables handing the difference at the water bottom between acoustically generated synthetic data and seismic data that corresponds to an elastic medium. The pseudo-? layer may be less than 100 m thick and/or may be located directly underneath the water bottom. The pseudo-? layer may have a negative value for S and a null value for ? (? and ? being Thomsen's anisotropy parameters).

  • Patent number: 10670752
    Abstract: Recorded seismic data are obtained at a plurality of receivers from a plurality of sources, and a set of sources from the plurality of sources is selected using spatial criteria based on a location of each source such that any two sources in the set of sources are separated by a predefined minimum distance of separation sufficient to reduce cross talk between sources. The set of sources is combined in a non-encoded manner into a composite source, and forward modeling for the composite source is performed to generate a synthetic seismic data set. A composite recorded seismic data set for the set of sources is determined, and the synthetic seismic data set and composite recorded seismic data set are used to determine a residual seismic data set. Backward modeling generates a gradient update used to generate an updated earth model.

  • Patent number: 10339234
    Abstract: An Earth model of a subsurface is created from acquired seismic data by migrating at least one of the incident wavefields and reflected wavefields to generate angle gathers for the seismic data and identifying for the subsurface an elastic Earth model equation for the incident wavefields and the reflected wavefields in the acquired seismic data. The elastic Earth model is a function of reflection angle between the incident wavefields and reflected wavefields and elastic parameters and is fit to the generated angle gathers through perturbation in the elastic parameters. The generated perturbations are used to create the Earth model of the subsurface.
