  • Publication number: 20230267594
    Abstract: Process for interpreting one or more borehole images for use in drilling operations. In some embodiments, the process can include providing an input borehole image obtained from a downhole measurement provided by one or more downhole sensors. The process can also include collecting contextual information relative to the borehole image and the user. The process can also include using the collected contextual information and a mathematical model to infer one or more processing arguments. The mathematical model can be defined by using previously collected arguments and previously collected contextual information. The process can also include processing the input borehole image with the one or more inferred processing arguments to generate one or more interpreted borehole images. The process can also include adjusting one or more drilling operation based, at least in part, on the one or more interpreted borehole images.

  • Publication number: 20230220762
    Abstract: The present disclosure introduces an apparatus including a toolstring for use in a tubular extending into a subterranean formation. The toolstring includes modular components that include one or more caliper modules and a power and control (P/C) module. The one or more caliper modules each include radially rotatable fingers for sensing an internal diameter of the tubular. The P/C module is operable for distributing power and control signals to the one or more caliper modules. The caliper and P/C modules are mechanically and electrically interconnected by common lower interfaces of the caliper and P/C modules.

  • Patent number: 10781692
    Abstract: A method for determining a property of a geological formation based on an optical image of rock samples taken from the formation is presented therein. The image comprises a plurality of pixels and the method comprises defining windows in the image, each window comprising predetermined number of pixels and being of a predetermined shape. The method also includes, for each window, extracting a rockprint value representative of the window. A rockprint comprises indicators for characterizing a texture of the window. The method also includes classifying the windows into categories of a predetermined set. Each category is representative of one type of rock and the classification is based on a comparison of the rockprint value of each window with rockprint values of images of reference rock samples for each category. Based on the classification, the method then includes determining the at least one property of the geological formation, ie the quantification of each type of rock in the sample.

  • Patent number: 10641922
    Abstract: In one embodiment, a computer-based method includes obtaining a borehole image deriving from a downhole tool in a borehole of a geological formation, performing dip picking on the borehole image to derive one or more structural dips, deriving a continuous structural dip based on the one or more structural dips, defining one or more locations of zone boundaries on the borehole image, deriving one or more zone boundaries based on the continuous structural dip and the one or more locations of zone boundaries, and defining one or more zones of the wellbore in a second image based on the one or more zone boundaries.
