  • Patent number: 11657090
    Abstract: Methods, apparatus, systems, and computer-readable media are set forth for processing exploration and production data to make such data more readily searchable for clients seeking to leverage the data for analytics and other services. The exploration and production data can be processed to generate a graph database that includes multiple nodes and node edges. The nodes can represent different portions of an exploration and production system, and the node edges can represent relationships between the different portions of the exploration and production system. Search suggestions be auto-filled at an interface of the graph database based on data available at the graph database. In this way, a user can be readily provide detailed search queries, without having to be completely cognizant of all the data available in the graph database.

  • Patent number: 11656199
    Abstract: Embodiments of the present disclosure are directed towards a method for obtaining and analyzing flux leakage data. Embodiments may include measuring, using a magnetic flux leakage tool, magnetic flux leakage data from a casing and determining sensor liftoff data from the flux leakage data. Embodiments may also include performing outward analytic continuation of the magnetic flux leakage data from a sensor plane to one or more additional planes and extrapolating back from the one or more additional planes to a surface. Embodiments may include applying a model-based parametric inversion to the magnetic field flux leakage data and determining, based upon, at least in part, the model-based parametric inversion, a shape and size of a corresponding corroded area associated with the casing.

  • Patent number: 11650347
    Abstract: Downhole properties of a geological formation may be determined using nuclear magnetic resonance (NMR) measurements obtained by a moving tool. To do so, an interpretation of the NMR data obtained by the moving data may take into account a moving model, characterization, or calibration of the downhole NMR tool. Additionally or alternatively, a partial interpretation mask may exclude interpretation of certain areas of data (e.g., T1-T2 data points or diffusion-T2 data points) that are expected to be less likely to describe downhole materials of interest.
