Abstract: System and methods used to localize microseismic events and determine the seismic moment tensor of microseismic events created by geological processes such as rock fracturing, rock slippage, fluid migration within rock pore spaces and man-made events such as hydraulic fracturing and reservoir stimulation. The recorded response from a microseismic event is usually contaminated with strongly correlated noise and to determine the most probable location of the source a unique processing method the maximum likelihood estimation (MLE) is applied.

Abstract: An apparatus, a method, and a non-transitory computer readable medium for event detection of passive seismic data are disclosed. The apparatus includes processing circuitry extracts features from the passive seismic data based on a backbone subnetwork of a residual deep neural network. The processing circuitry generates bounding box proposals for a region of interest (ROI) in the passive seismic data based on the extracted features being input to a region proposal network of the residual deep neural network. The processing circuitry classifies the bounding box proposals into two groups. Each bounding box proposal in a first group indicates that a corresponding seismic signal presents in the ROI. Each bounding box proposal in a second group indicates that no seismic signal presents in the ROI. The processing circuitry determines at least one seismic signal in the ROI from the first group of bounding box proposals.

Abstract: A remote determination system of seismic sensor orientation comprises: a data collection unit that receives earthquake waveforms and microseism records; a data analysis unit that analyzes earthquake P-waves and earthquake Rayleigh-waves of the earthquake waveforms and analyzes microseism of the input microseism records; a reference seismic sensor selection unit that selects a reference seismic sensor using analysis results derived from the data analysis unit; a misorientation angle determination unit that determines a misorientation angle of a target seismic sensor, using an apparent radial direction determined through microseism analysis and the reference seismic sensor; and a final representative value determination unit that determines a final representative value of a seismic sensor orientation, by collecting a seismic sensor orientation estimate from the earthquake P-wave analysis, a seismic sensor orientation estimate from the earthquake Rayleigh-wave analysis, and a seismic sensor misorientation angle determination value from the misorientation angle determination unit.

Abstract: A system includes a first wellbore operation controller for controlling a wellbore operation and generating a first broadcast indicating a first data topic desired for controlling the wellbore operation. The system also includes a second wellbore operation controller for generating a data stream associated with a wellbore and for generating a second broadcast indicating a second data topic that promotes the data stream. The system includes a mediator computing device that receives the first broadcast and the second broadcast and determines that the first wellbore operation controller is subscribed to the data stream by comparing the first data topic to the second data topic. In response to determining that the first wellbore operation controller is subscribed to the data stream, the mediator computing device creates a data link between the first wellbore operation controller and the second wellbore operation controller.

Abstract: A method for mapping fiber optic distributed acoustic sensing (DAS) measurements to particle motion involves obtaining, from a fiber optic DAS system in a wellbore, a first set of DAS data associated with a first seismic wave; obtaining, from a discrete seismic receiver in the wellbore, measured particle motion data associated with the first seismic wave; generating training data from the first set of DAS data and the measured particle motion data; training a machine learning model using the training data; obtaining a second set of DAS data associated with a second seismic wave; and determining a predicted particle motion in response to the second seismic wave using the machine learning model applied to the second set of DAS data.

Abstract: A method of identifying hydrocarbon production information is disclosed. In in a first hydrocarbon management environment, a first audio signal is detected and a characteristic acoustic fingerprint is identified therefrom. The fingerprint is stored in a memory, along with identifying information associated with the first signal. A second audio signal is detected and a characteristic acoustic fingerprint is identified therefrom. The fingerprints are compared, and if the fingerprints match the identifying information of the first audio signal is assigned to the second audio signal. A notification regarding the matching of the characteristic acoustic fingerprints of the first and second audio signals is issued.

Abstract: The invention provides a method of detecting a seismic event, which comprises acquiring (110) a digital signal x characteristic of a signal measured by at least one seismic sensor, and calculating (130) a time-frequency distribution for at least one section of a given duration of said signal, in a given frequency band. For each frequency of said frequency band, the calculated time-frequency distribution is normalized. The method also comprises calculating (150) the moving average of the normalized time-frequency distribution ZD, in said frequency band and in a time window, given reference L, centered on the time n; and detecting (160) a seismic event when the average exceeds a predefined threshold value. The invention also provides a corresponding detection system.
