Abstract: Some methods of scale and corrosion monitoring of a well include receiving information from a plurality of transducers disposed in a ring on a circumference of a tubing of the well, the received information including frequency domain information representing a first longitudinal ultrasonic wave and a first torsional ultrasonic wave to arrive at the plurality of transducers; determining arrival times for the first longitudinal ultrasonic wave and the first torsional ultrasonic wave to arrive at the plurality of transducers based on the received information; comparing the determined arrival times with a range of predetermined arrival times from a model that accounts for wave refraction using a ray tracing scheme to determine a wall thickness of the tubing, a scale thickness of scale within the tubing, and a scale shear wave velocity of the scale; and identifying a material of the scale based on the determined scale shear wave velocity.

Abstract: The disclosure addresses multiple embodiments of an acoustic isolator, and an acoustic logging tool which incorporates the acoustic isolator. The acoustic isolator is configured to minimize acoustic transmissions which could otherwise adversely affect acoustical measurements being made by an acoustic receiver. The described acoustic isolators include a plurality of longitudinally arranged mass members coupled to a central supporting structure, in a configuration to reduce acoustic transmissions in at least selected frequency ranges.

Abstract: Adaptive stimulation systems combine impulse-generated swept-frequency stimulation vibration with cyclically-varying hydraulic pressure to provide adaptive down-hole stimulation. Swept-frequency stimulation vibration arises from cyclical shifts of the power spectral density (PSD) of each stimulator's fluid interface vibration (via closed-loop control of the rebound cycle time and/or the fluid interface's effective elastic modulus). PSD's are adjusted for resonance excitation and fracturing of geologic materials at varying distances from a wellbore, closed-loop control incorporating backscatter vibration from stimulated geologic material. One or more stimulators generate vibration in bursts comprising a plurality of vibration frequencies. Timed signals from a programmable controller affect directional propagation of combined vibration wave fronts from a stimulator array. As fracturing proceeds to smaller (e.g., proppant-sized) fragments having higher resonant frequencies, PSD's are up-shifted, increasing relative stimulation vibration power in higher frequencies. Progressive stimulation is thereby optimized, facilitating plain-water (or liquefied propane) fracs with self-generated proppant.

Abstract: In accordance with embodiments of the present disclosure, systems and methods for improving performance of ultrasonic transducers, particularly those used in borehole environments, are provided. The disclosed ultrasonic transducers all feature a backing element that is a ceramic backing material. The ceramic backing material may include a solid piece of ceramic material that is disposed on a back end of a piezoelectric element used in the ultrasonic transducer. The disclosed ceramic backing material may be used to mechanically match the backing element to the piezoelectric source element, while minimizing the amplitude of reflections of the ultrasonic pulse generated by the piezoelectric element and reflected at the far end of the backing element. This ceramic backing material may provide consistent performance regardless of the surrounding pressure and temperature, making it particularly useful in borehole applications.

Abstract: A push-the-bit rotary guiding device includes a mandrel having a central passage; a sleeve which is rotatably sleeved outside the mandrel; a plurality of swing ribs which are circumferentially arranged in an outer wall of the sleeve with an interval; an actuation mechanism, for controlling each swing rib to swing respectively; a plurality of detectors, which are circumferentially arranged in the outer wall of the sleeve with an interval, for detecting a distance to a well wall in real-time; and a controller, for determining whether the actuation mechanism is required to actuate the swing ribs to swing according to the detected distance. An application method of the push-the-bit rotary guiding device is provided. According to the push-the-bit rotary guiding device, through a real-time detection of the detectors, a well section having an expanded or reduced diameter is detected in time and guiding of the rotary guiding device herein is avoided.

Abstract: Systems and methods for actively controlling the damping of a wellbore logging tool are disclosed herein. A wellbore logging tool system comprises a processor, a memory, a wellbore logging tool comprising an acoustic transmitter, and a logging tool control module. The logging tool control module is operable to receive sensor signals from one or more sensors coupled to the wellbore logging tool after an actuation control signal has been transmitted to the acoustic transmitter and determine, using the received sensor signals, one or more current dynamic states of the acoustic transmitter. The logging tool control module is also operable to determine a damping control signal based on the one or more current dynamic states of the acoustic transmitter and transmit the damping control signal to the acoustic transmitter of the wellbore logging tool.
