摘要： Systems and methods process a measured ultrasonic response waveform to determine a well casing thickness and an acoustic impedance of a sealing medium surrounding the well casing. An array of simulated response waveforms corresponding to a set of candidate acoustic impedances for the sealing medium surrounding the well casing and a set of candidate well casing thicknesses is generated. A simulated response waveform from the array of simulated response waveforms is identified that best matches the measured response waveform so as to determine the sealing medium acoustic impedance.

摘要： A method for monitoring tubing wall thickness includes conveying a tool through a tubular string in a borehole, the tool including a photon source that directs a photon beam along a radial path toward a wall of the borehole, the tool further including an array of collimated detectors that measure Compton backscattering rates at respective distance bins along the radial path. The method further includes calculating a sequence of ratios between measurements from neighboring detectors. The method further includes identifying one or more local extrema in the sequence, each extremum representing a boundary between different materials. The method further includes determining a wall thickness of the tubular string from absolute or relative positions of the one or more extrema. The method further includes displaying a representation of the wall thickness.

摘要： A method for cement evaluation may include generating a gamma ray, from a radioactive source, into cement disposed between a casing and a geological formation. Photons reflected from the geological formation and the cement are detected on a gamma detector having a collimator. A detector-to-source distance, a collimator angle, and/or a collimator diameter are set to provide an energy spectra independent of the geological formation. The quality of the cement may be determined based on the energy spectra of the detected photons.

摘要： An apparatus and method may operate to mount acoustic sensors, azimuthally offset from each other, to the exterior of a casing. After the casing and acoustic sensors are in the borehole, signals are provided to the acoustic sensors to cause the acoustic sensors to emit acoustic signals into the annulus around the casing. The method further includes detecting reflected compression waves, shear waves or a combination or conversion thereof at the acoustic sensors to generate a set of two]way travel times of the acoustic signals. The method can further include generating distance measurements of a distance between corresponding acoustic sensors and points on the borehole wall based on the two]way travel times, to determine a position of the casing within the borehole. The method can further include identifying fluids based on the two]way travel times. Additional apparatus, systems, and methods are disclosed.

摘要： The present invention is a system and method for measuring borehole conditions, in particular for verification of a final diameter of a borehole. The system includes a drill string with a drill bit and a drilling mud circulation device, an underreamer attached to the drill string above the drill bit, and a tool body attached to the drill string, having a sensor for detecting downhole conditions, such as borehole diameter. The tool body is mounted above the underreamer and has a diameter smaller than the underreamer and drill bit. The sensor can be an ultrasonic transducer with a sensor housing for adjustable distance to particular borehole size. The system may also include a calibrator for sensor data, and an auxiliary tool body with another sensor between the drill bit and the underreamer.
