  • Compressional velocity correction apparatus, methods, and systems
    Patent number: 9547098
    Abstract: In some embodiments, an apparatus and a system, as well as a method and an article, may operate to measure compressional wave velocities in a geological formation surrounding a first well, to provide measured compressional wave velocity data, and to subsequently determine corrected compressional wave velocities for the first well. These corrected compressional wave velocities for the first well may be determined using a combination of the measured compressional wave velocity data and corrected compressional wave velocity data associated with one or more second wells. Predicted pore pressure data for the first well may be subsequently generated, using the corrected compressional wave velocities for the first well. Additional apparatus, systems, and methods are described.
