Abstract: A method for identifying a wellbore condition includes capturing a first image of cuttings on or downstream from a shale shaker using a first camera. A size, shape, texture, or combination thereof of the cuttings in the first image may be determined. A wellbore condition may be identified based on the size, shape, texture, or combination thereof of the cuttings in the first image.

Abstract: A method includes determining a rotational position of a crankshaft in a multiplex pump from one or more sensors disposed on the crankshaft, determining a position of each of a plurality of pistons along a corresponding pump bore in relation to a total stroke length of each piston and a connecting rod length, calculating an individual theoretical displaced volume of fluid for each of the pump bores in the multiplex pump based on the rotational position of the crankshaft, and summing the individual theoretical displaced volumes to determine a total theoretical pumped volume by the multiplex pump. A calibration method includes determination of the multiplex pump efficiency versus speed and discharge pressure, and the effect of pump leakage and valve closing delay on the pump efficiency. Verification of the pump performance and efficiency may be controlled during pumping to insure the validity of the last calibration data set.

Abstract: A system and method to reduce a whirl effect on a rotation of a drill string with an AC induction motor mechanically coupled to a rotary drilling system and configured to drive the rotary drilling system and the drill string attached thereto. Additionally, the system includes an electronic inverter to generate supplied power for the AC induction motor and a controller configured to drive the operation of the electronic inverter to impose a virtual drive characteristic relating a torque output of the motor with speed of the motor, determine a desired nominal operating point, and determine presence of whirl in the drill string from torque of the rotary drilling system and speed of the drill string.

Abstract: A system for offline suspension of a tubular including a first well having a first wellbore and a cellar formed at the surface of the first well with a rig movable from the first well to a second well. Additionally, a tubular string extending into the first well and a tubular support structure above the cellar of the first well, wherein the tubular support structure supports a weight of the tubular string such that the tubular is suspended from the tubular support structure independent from the rig and through a securing equipment configured to secure the first well.

Abstract: Methods and systems for acquiring data in a wellbore. The method includes deploying an instrument connected to an instrument line into a drill string, through a sealed entry port formed in a drilling device coupled to the drill string, the drill string being at least partially within the wellbore, the wellbore penetrating a subterranean formation. The method also includes transmitting a signal from a source and through the formation. The signal is sensed by the instrument in the drill string. The method further includes determining one or more formation characteristics based on the signal sensed by the instrument, and performing one or more drilling processes using the drill string, while transmitting the signal, determining the one or more formation characteristics, or both.

Abstract: A top-drive system and a drilling rig. The top-drive system includes a sheave configured to receive a drilling line, a frame coupled with the sheave and configured to transmit a weight of a tubular string suspended therefrom to the sheave, a controller, and a sensor in communication with the controller. The sensor is configured to directly measure one or more physical parameters of a drilling operation and provide data representing the one or more physical parameters to the controller.
