Abstract: Apparatus and methods pertaining to a moveable well construction apparatus to be electrically energized via an electrical power transmission path extending between a stationary power source and the moveable well construction apparatus. The path comprises cables and connectors. A system comprises a detector operable for generating information indicative of whether the path is properly installed. The system permits the path to be electrically energized when the detector-generated information indicates the path is properly installed, and prevents the path from being electrically energized when the detector-generated information indicates the path is not properly installed.

Abstract: A method for transmitting data from a downhole tool to a surface location includes measuring a property in a wellbore using a downhole tool in the wellbore. A casing is positioned within the wellbore, and the downhole tool is positioned below at least a portion of the casing. A digital frame is generated using the downhole tool. The digital frame includes information corresponding to the property. The digital frame is encoded to superpose the information on a carrier signal. The carrier signal is converted to a voltage differential that is generated across an insulation layer in the downhole tool. The voltage differential causes a current to flow through a subterranean formation and into the casing above the downhole tool. A magnetic flux generated by the current flowing through the casing is detected using a sensor that is positioned at least partially within or at least partially around the casing.

Abstract: Systems and methods for continuous mud circulation during a drilling operation. The method includes delivering a first flow of drilling mud from a mud supply, through a drill string, into a wellbore, and through a blowout preventer. The drill string is received through the blowout preventer. The method also includes delivering a second flow of drilling mud into the blowout preventer. The second flow is not delivered through the drill string. The method further includes stopping the first flow, and removing or adding a tubular to or from the drill string when the first flow is stopped and while continuing to deliver the second flow.

Abstract: An electric submersible pump (ESP) with reduced vibration is provided. In an implementation, an ESP section has radial bearings placed at shaft locations of reduced vibration to reduce wear. The locations of reduced vibration are selected to avoid areas of high vibration and vibrational waves that reinforce each other due to structure resonance and natural excitation frequencies. In an implementation, a radial bearing is positioned at a node of reduced vibration of a standing vibrational wave. In an implementation, a succession of multiple radial bearings are spaced at different intervals from each other to avoid conventional even spacing of the bearings that causes standing waves, resonance waves, and vibrational waves at natural excitation frequencies. In an implementation, a span between adjacent radial bearings is selected to spare other adjacent bearings at different spans the effects of vibrations that may extend over a range of excitation frequencies in the ESP section.
