Abstract: Aspects of the subject technology relate to downhole sensing system are disclosed. The system has a first collar configured to accept a receiver, a second collar configured to accept a transmitter; and an acoustic isolator disposed between the first collar and the second collar. The acoustic isolator has a tubular body with a generally smooth exterior surface and an interior surface with a plurality of circumferential grooves formed in the interior surface that modify the acoustic impedance of the tubular body, thereby attenuating an acoustic signal passing through the tubular body.

Abstract: A system includes an acoustic attenuation interface disposed between a first acoustic transmission conduit and a second acoustic transmission conduit. An acoustic signal source acoustically coupled to the first acoustic transmission conduit generates an acoustic signal. An acoustic noise source acoustically coupled to the second acoustic transmission conduit generates an acoustic noise. A first sensor is configured to detect a first composite signal including the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and an attenuated acoustic noise. A second sensor is configured to detect a second composite signal including the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and attenuated by the acoustic attenuation interface and the acoustic noise. An acoustic signal processing system is configured to determine a noise-reduced signal from the first composite signal and the second composite signal.

Abstract: A downhole tool having an acoustic transducer for downhole measurements. A backing is in contact with an inner surface of the transducer. A first structure is coupled to a first housing. A second structure is coupled to a second housing. A member includes first, second, and third portions. The first portion is coupled to the first structure. The second portion is coupled to the second structure. At least one of the first and second structures is coupled to the member and has a degree of freedom relative to the member. The third portion extends longitudinally through the backing between the first and second portions such that compressional forces on the first and second housings are transferred through the first and second structures and the backing. A canister contacts an outer surface of the transducer and exerts radial forces on the transducer when exposed to pressures higher than atmospheric pressure.

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: A shock absorber (29) for downhole use comprises an elongate, hollow member defined by a series of mutually aligned, plastically deformable perforated members (38) having aligned perforations that define the hollowness of the elongate, hollow member that are spaced from one another in the direction of elongation by respective relatively rigid spacer members (39) that are secured to the perforated members. The elements of each pair of perforated members (38) of the series are so spaced from one another by one or more of the spacer members (39) such that on compression of the shock absorber (29) the perforated members (38) deform plastically to a lesser extent in regions at which the spacer members (39) are secured than at other regions. The arrangement of the perforated members (38) and the spacer members (39) causes compression to occur substantially parallel to the length of the shock absorber (29).

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.
