    Abstract: Aspects of the disclosure can relate to a system for tracking fatigue damage experienced by a tool in real-time. The system can include a processor operably coupled to a memory and operable to execute one or more modules to generate master curve fitting coefficients for a connection type associated with a tool component (e.g., a component of a bottom hole assembly). The master curve fitting coefficients can be for a threaded connection master curve, a port hole master curve, and so forth. The processor can also be operable to execute the one or more modules to generate a fatigue calculator for the tool component. The system may receive a real-time trajectory for the tool, determine a curvature from the trajectory of the tool, determine a bending moment based upon the curvature, and determine fatigue damage for the tool component based upon the bending moment using the fatigue calculator.

    Abstract: A method for magnetic ranging includes rotating a drilling tool in a drilling well in sensory range of an AC ranging signal emanating from a target well. The drilling tool includes a magnetic field sensor rotatably coupled thereto. The magnetic field sensor obtains a plurality of magnetic field measurements while rotating. The magnetic field measurements are mathematically back-rotated to obtain back-rotated magnetic field measurements which are in turn processed to obtain a measurement of the AC magnetic ranging signal emanating from the target well. The AC magnetic ranging signal is then processed to compute at least one of a distance and a direction from the drilling well to the target well.

    Abstract: Aspects of the disclosure can relate to simulating expected sensor values associated with a drill tool (e.g., a drill assembly) before drilling to monitor the sensor. A planned trajectory for the drill assembly is received, where the planned trajectory is associated with a borehole to be drilled by the drill assembly along a geographic path. Next, an expected position for the drill assembly is determined along the geographic path. Then, an expected sensor value for a sensor associated with the drill assembly is simulated at the expected position. Next, an actual sensor value at an actual position corresponding to the expected position is determined. Then, the expected sensor value and the actual sensor value are dynamically displayed together at a user interface.

    Abstract: Methods, systems, and computer-readable media for assessing porosity and water saturation cutoff values for hydrocarbon volume estimation are described. The techniques can include determining a plurality of water saturation and porosity value pairs for locations regularly-spaced along at least one borehole. The techniques can further include plotting the plurality of water saturation and porosity value pairs on a graph and representing a plurality of percentiles of the estimated maximal hydrocarbon volume on the graph. The techniques can also include causing the graph to be displayed to a user, such that the user can visually observe a combined sensitivity to porosity and water saturation cutoffs values. The user can take various actions based on the display.

    Abstract: A tool with a hydraulic lock mechanism may include a body defining a flow tube and a chamber. An expandable member may be coupled to the body. A first valve may be located between the chamber and the flow tube to control the flow of fluid into the chamber from the flow tube. A second valve may located between the chamber and an external environment to control the flow of fluid from the chamber into the external environment. The first and second valves may trap fluid within the chamber to maintain the tool in an active position. A piston may be connected to the expandable member and may move in response to pressurization of the chamber. At one position, the piston may cause the expandable member to extend to a radially outward position. At another position, the piston may cause the expandable member to retract to a radially inward position.
