Abstract: A technique facilitates monitoring of acoustic signals to measure a velocity vector of a borehole. Acoustic sensors are arranged in a desired acoustic sensor array and positioned along a body of a tool, e.g. a sonic logging tool. The acoustic sensor array is then positioned in fluid along a wall of a borehole formed in a subterranean formation. The acoustic sensors are used to collect acoustic signal data while the acoustic sensors are maintained in a non-contact position with respect to the wall of the borehole. The data may be processed to determine the desired velocity vector.

Abstract: A technique facilitates use of acoustic measurements to enable geo-steering during a well operation. A steerable well string is provided with acoustic systems used to collect data which is then processed to determine geo-steering inputs. In some applications, the well string may comprise a coiled tubing drilling tool. The coiled tubing drilling tool or other well string tool is combined with an azimuthally distributed pitch-catch micro-sonic sensor system and an azimuthally distributed ultrasonic pulse-echo transducer system. Data from these two systems is provided to a processing system which processes the data to determine, for example, real-time, geo-steering inputs. These inputs may then be used to more effectively steer the coiled tubing drilling tool or other well string tool.

Abstract: Methods and apparatus pertaining to determining shape and size of a borehole at a depth within a subterranean formation using ultrasonic measurements obtained by a downhole tool at four different azimuthal locations corresponding to four mutually orthogonal directions extending radially from a central axis of the downhole tool. The measurements are indicative of a distance between a wall of the borehole and the downhole tool at each azimuthal location. The borehole shape and size are determined by estimating an ellipse approximating the borehole shape and size using the ultrasonic measurements.

Abstract: Methods and systems of measuring acoustic signals via a borehole wall are disclosed. One or more non-contact magneto-dynamic sensors are configured or designed for deployment at at least one depth in a borehole. The magneto-dynamic sensor comprises a coil excited by an electric current and a circuitry for outputting a signal corresponding to a time-varying impedance of the coil. A processor is configured to perform signal processing for deriving at least one of a magnitude or a frequency of vibration of the borehole wall based on the output signal from the circuitry.

Abstract: A technique facilitates the accumulation and analysis of data related to a subterranean formation. An arrangement of different types of sensors is mounted on a collar utilized in accumulating data on the subterranean formation. The sensors are operable in combination to improve the image quality of data obtained with respect to the subterranean formation.

Abstract: A technique facilitates acoustic measurement and analysis in a variety of acoustic applications. An acoustic source is provided with a housing, e.g. a cylindrical housing, and a motor located within the housing. A piston is driven by the motor. The acoustic source also is provided with a radiating plate mounted along the housing and exposed to an environment surrounding the housing. A fluid passage contains actuating fluid and extends between the piston and the radiating plate. The piston and the radiating plate are linked by the fluid passage such that reciprocation of the piston by the motor causes oscillation of the radiating plate to create an acoustic signal. In some applications, a plurality of radiating plates and/or a plurality of motors may be arranged to enable monopole, dipole, cross-dipole, and/or quadrupole measurements.
