Publication number: 20230393099Abstract: Methods to perform through tubing cement evaluation using converted multipole resonance modes. A first acoustic transmission is emitted outward toward the cement such that a portion of the first acoustic transmission penetrates the cement. The receiver array detects the first acoustic response derived from the first acoustic transmission. The system then determines the multimode wellbore resonance based on the first acoustic response. In response to the first acoustic transmission penetrating the cement, a first mode of the multimode wellbore resonance is converted into a second mode different from the first mode. The receiver array detects a second acoustic response derived from the converted mode of the multimode wellbore resonance. The system determines the converted mode using the second acoustic response. A property of the cement is evaluated based on the multimode wellbore resonance and the converted mode.Type: ApplicationFiled: June 1, 2022Publication date: December 7, 2023Inventors: Yao Ge, Ruijia Wang, Ho Yin Ma

Patent number: 11733419Abstract: Ringdown noise can be estimated and removed from a waveform captured by a downhole tool. Ringdown may be estimated by calculating a median of waveforms from a number of tool firings. The estimated ringdown may then be subtracted from a waveform currently being processed. The resulting waveform contains a more accurate representation of a true echo signal reflected from the borehole wall or formation. In some embodiments, the acoustic transducer's deterministic waveform may be learned by statistical analysis of other waveforms near in time to the presently measured waveform. In other embodiments, the deterministic waveform may be learned via previously acquired waveforms now stored in memory, or through predictive waveforms developed in laboratory testing conditions similar to those experienced downhole.Type: GrantFiled: December 27, 2018Date of Patent: August 22, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Yao Ge, Xiang Wu, Jing Jin

Patent number: 11674383Abstract: A hydrophone array tool as described herein is configured to locate leakages throughout a borehole with improved accuracy using acoustic beamforming techniques with acoustic velocity estimation. An acoustic beamforming processor generates an initial beamforming map and corresponding initial estimated leakage location using acoustic measurements throughout the borehole.

Publication number: 20230175391Abstract: The disclosure presents processes to determine the direction and magnitude of tubing eccentricity along the length of a tube inserted within a borehole. The tubing can be a wireline, a drill string, a drill pipe, or tubing capable of allowing fluid or other material to flow through it. As borehole operations proceed, the tubing can move toward the side of the borehole. This eccentricity can cause excess wear and tear on the tubing, on the casing of the borehole, or on the inner surface of the subterranean formation. The eccentricity can be measured using acoustic signals that are collected downhole covering the azimuthal angles 0° to 360° at a location in the borehole. The collected signals can be filtered, transformed, and analyzed to estimate the tubing eccentricity. Other processes and systems can use the results to obtain cement bond evaluations through tubing and to determine preventative or restorative actions.Type: ApplicationFiled: December 6, 2021Publication date: June 8, 2023Inventors: Brenno Caetano Troca Cabella, Xiang Wu, Marco Aurelio Luzio, Pablo Vieira Rego, Chung Chang, Federico Combis Lucas, Yao Ge, Ruijia Wang, Ho Yin Ma
