A magnetic flux receiver assembly includes a collar that defines a central passageway and an axial collar face, and a tool insert disposable within the central passageway and defining an axial insert face. One or more magnetometers are operatively coupled to the tool insert. One or more buttons are coupled to one or both of the axial collar face and the axial insert face such that an axial gap is defined at an axial interface between the axial collar face and the axial insert face to prevent electrical communication across the axial interface.

A system for tracking and steering a downhole tool using an augmented reality device. A tracker tracks the location of a downhole tool as it moves underground and transmits data to the device, while one or more sensors measure a position and orientation of the device. The device analyzes the data received from the tracker and the sensors and generates a virtual image of the downhole tool. The virtual image is displayed on the device at its detected location relative to the ground surface and relative to the position of the device. The position of the displayed virtual image is modified in response to updated information from the tracker or the sensors. Virtual images representing various parameters of the drilling operation are also displayed on the device in juxtaposition with the virtual image of the downhole tool.

A lid for use with a downhole tool configured to house a beacon. The lid has an exterior and interior surface. A board is attached to the interior surface of the lid and electronic hardware is positioned between the board and the interior surface of the lid. The electronic hardware includes a pressure sensor. The pressure sensor is installed within the lid so that it is communicable with the exterior surface of the lid. When the downhole tool is positioned within an underground borehole, the pressure sensor measures the fluid pressure of any fluid surrounding the downhole tool. Measurements taken by the pressure sensor are transmitted to the beacon housed within the downhole tool. The beacon subsequently transmits such measurements to a tracker located at the ground surface.

The way in which a fiber optic cable is wrapped around a casing string in a wellbore can be modeled using information from downhole sensor devices. For example, a system can include a fiber optic cable located along a length of a wellbore. The system can also include sensor devices located near the fiber optic cable at various depths to transmit acoustic signals indicating depths and orientations of segments of the fiber optic cable. The system can build a model describing how the fiber optic cable is positioned around the casing string based on the acoustic signals transmitted from the sensor devices. The system can also determine a target position for a perforating gun to perform a perforation operation through the casing string that avoids damaging the fiber optic cable. The system can output the target position for the perforating gun to an electronic device to facilitate the perforation operation.

A method for locating a buried casing stub may comprise a) identifying a target region, b) providing at each of a plurality of survey points in the target region a casing stub locator that includes a vector magnetometer, c) measuring the magnetic field at each of the survey points using the vector magnetometer so as to generate a plurality of magnetic field measurements, d) using the magnetic field measurements to generate a model of the magnetic field of the target region, e) fitting the model generated in step d) to a selected model of a magnetic anomaly created by the casing stub so as to generate model fit information (MFI), and f) locating the casing stub using the MFI. At each survey point, an expected Earth magnetic field can be subtracted from the measured magnetic field. A total station can measure the position and/or the azimuth of the package.

A tracking system for communicating a location of a beacon in order to drill a bore path. The beacon is carried by a drill string in a drilling operation. Above-ground trackers are arranged in a path to define an intended underground bore path. The trackers form a multi-node mesh network in communication with a display unit at a drilling rig. A drilling operator guides the drill string in response to tracking data sent from the tracking system.
