  • Publication number: 20150301213
    Abstract: A method for processing acoustic waveforms comprises acquiring acoustic waveforms in a borehole traversing a subterranean formation and transforming at least a portion of the acoustic waveforms to produce frequency domain signals. Then model dispersion curves are generated based on an anisotropic borehole-formation model having a set of anisotropic borehole-formation parameters. The frequency-domain signals are back-propagating using the model dispersion curves to correct dispersiveness of the signals and coherence of the back-propagated signals is calculated. Alternatively the difference between the measured and the model dispersion curves is determined. Model parameters are iteratively adjusted until the coherence reaches a maximum or exceeds a selected value, or alternatively until the difference between the measured and the model dispersion curves becomes minimal or is reduced to below a selected value. Then at least a portion of the set of anisotropic borehole-formation parameters is obtained.

  • Publication number: 20150222476
    Abstract: Provided is a server device capable of increasing the availability of a device by urging a user who uses the device to perform actions related to maintenance service. In this server device, an information transceiver receives operation information about a device. A remaining life determination unit determines the remaining life of the device or a component of the device based on the operation information. When the determined remaining life reaches a predetermined remaining life or becomes shorter than the predetermined remaining life, a transmission destination setting unit sets a device that is possessed by a person having a predetermined relationship with the user of the device as a transmission destination for the transmission of maintenance service information based on relationship information indicating the relationship between the user of the device and another person who is not the user. The information transceiver transmits the maintenance service information to the transmission destination.
