  • Patent number: 11441415
    Abstract: Wellbore cement compositions can be managed based on material characteristics determined from a cement sample. For example, a cement sample can be retrieved from a wellbore. The cement sample can be analyzed using a plurality of sensors to generate a three-dimensional mapping of particles in the cement sample. The three-dimensional mapping can represent three-dimensional spatial relationships between the particles in the cement sample. The three-dimensional mapping can be compared to baseline three-dimensional mappings in a database. The comparison of the three-dimensional mappings can be used to identify at least one material characteristic of the cement sample. Based on the at least one material characteristic of the cement sample, a cement mixture can be prepared or information related to the cement mixture can be output.

  • Patent number: 11415531
    Abstract: Methods and systems for selecting mode(s) for inspection of specimens are provided. One method includes statistically predicting if data points in a set correspond to defects or nuisances on a specimen. The data points include attribute(s) determined for discrete locations on the specimen from output generated by two or more modes of an inspection system. Events have been detected at the discrete locations with at least one of the modes. The method also includes determining a quantitative measure for each of two or more different combinations of the modes thereby determining different quantitative measures. The quantitative measure for each of the different combinations is responsive to how well one of the combinations detects the defects and minimizes detection of the nuisances. The method further includes selecting one or more of the modes for inspection of specimens of the same type as the specimen based on the determined quantitative measures.
