  • Publication number: 20210256671
    Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for controlling borehole imaging blending through machine learning. A blending parameter machine learning model can be trained through a supervised machine learning technique with a dataset of known input and known output associated with an electromagnetic imager tool. The blending parameter machine learning model is associated with an image blending technique for blending images generated through the electromagnetic imager tool at different frequencies. One or more blending parameters for the image blending technique can be identified by applying the blending parameter machine learning model to measurements of the electromagnetic imager tool operating to log a wellbore across a plurality of frequencies. One or more blended images can be generated by applying the image blending technique according to the one or more blending parameters to a plurality of images of the measurements made by the electromagnetic imager tool.

  • Patent number: 10823873
    Abstract: Hybrid frequency/time-domain modeling may be used to compute the synthetic transient response to an eddy-current pulse for use in a high-dynamic-range and efficient inversion method for pulsed-eddy-current pipe inspection tools. In accordance with some embodiments, frequency-domain response signals are computed for a plurality of frequencies and converted, by frequency-to-time-domain transformation, to a first synthetic transient response signal. A time boundary associated with an onset of spurious oscillations in the first synthetic transient response signal is then automatically determined, and a second synthetic transient response signal beginning at the determined time boundary is determined directly with a time-domain numerical technique. A portion of the first synthetic transient response signal ending at the time boundary may be combined with the second synthetic transient response signal.
