  • Patent number: 11898435
    Abstract: Borehole images can be corrected using machine-learning models. For example, a system can train a machine-learning model based on a training dataset. The training dataset can include a first set of borehole images correlated to a second set of borehole images, where the second set of borehole images are less precise versions of the first set of borehole images. The system can then execute the trained machine-learning model in relation to an input borehole image to receive a corrected borehole image as output from the trained machine-learning model. The corrected borehole image can be a visually corrected version of the input borehole image. The system may then perform one or more operations based on the corrected borehole image, such as generating a graphical user interface that includes the corrected borehole image for display on a display device.

  • Patent number: 11874424
    Abstract: A geosignal is calculated based on a signal detected by a multicomponent resistivity tool (101) to facilitate determination of formation properties and infer location of the resistivity tool with respect to formation boundaries. The resistivity tool (101) detects an electromagnetic field response signal (109) at a series of azimuth angles (111) during one tool rotation. The signal measured at each azimuth angle is decoupled to obtain nonzero electromagnetic field tensor components for input into the geosignal calculation. The results of the geosignal calculation for at least a top bin (i.e., an azimuth angle of 360 degrees) and a bottom bin (i.e., an azimuth angle of 180 degrees) are evaluated to determine whether the tool (101) is near a formation boundary. If the tool is determined to be near a formation boundary, the resistivity of the layers of the formation on each side of the detected boundary can be inferred.

  • Publication number: 20230383643
    Abstract: A system can calibrate inconsistencies in a wellbore tool. The system can receive a first set of measurements and a second set of measurements with respect to different electromagnetic antennas. The system can decouple a first multi-components tensor corresponding to the first set of measurements and a second multi-components tensor corresponding to the second set of measurements. The system can determine, using the decoupled first and second multi-components tensors, a scaling factor. The system can apply the scaling factor to a raw measurement received with respect to an electromagnetic antenna of the wellbore tool positioned in a wellbore to decouple a third multi-components tensor or to decoupled components of a fourth multi-components tensor for controlling a wellbore operation.
