(under subclass 152.54) Subject matter wherein the determination of the characteristic of the borehole, the casing, or the drill rigging is made by measuring the effect of the borehole casing or the drill rigging on vibration.

152.15, for determining a formation logging by plural tests including measurements of radioactivity and vibration.
152.16, for determining a formation logging by plural tests including a measurement of vibration and no measurement of radioactivity.
152.32, for determining a rate of fluid flow within a borehole by measuring the effect of the rate of fluid flow on vibration.
152.47, for making a downhole measurement of a characteristic of a borehole, a casing, or a drill rigging by measuring vibration during drilling.
152.57, for a downhole vibration test of cement or a casing within a borehole.

181, Acoustics, for acoustic exploration within a borehole.
367, Communications, Electrical: Acoustic Wave Systems and Devices,
25+, for the communication of information or intelligence in the form of acoustic waves traveling through earth and
detected by electric signal handling means passing through a well bore and providing information pertaining to a characteristic or a location of discontinuities within the earth, subclasses 81+ for the communication of information or intelligence in a well bore in the form of acoustic waves traveling in a medium in the well bore different from the surrounding earth and providing information pertaining to a characteristic of the well bore or a location of discontinuities within the earth, and subclasses 86+ for the communication of information or intelligence in the form of acoustic waves traveling through earth and detected by electric signal handling means (a) passing through a well bore and (b) providing information pertaining to a characteristic of a borehole or a location of discontinuities within the earth for electroacoustic borehole testing and wherein the intelligence pertains to the walls of the borehole and is obtained from a device which travels through the passageway and emits acoustic waves into a medium contained within the borehole (e.g., water, air, etc.) which are reflected from the walls back to the device and are detected.
