Abstract: Performing a corrective action includes obtaining assembly parameters indicating assembly information of a drilling component and drilling parameters indicating drilling information associated with the drilling component, monitoring the assembly parameters and the drilling parameters for a period of time, the period of time being dynamically configured or a preconfigured period of time, comparing the assembly parameters to threshold assembly parameters and the drilling parameters to threshold drilling parameters; determining whether the assembly parameters meet the threshold assembly parameters or the drilling parameters meet the threshold drilling parameters, and triggering a corrective action that modifies an application configuration associated with the drilling component.

Abstract: A top drive drilling system, in at least some aspects, having a top drive unit, and a pipe gripping system beneath the top drive unit which has an open throat for receiving a tubular to be gripped by the pipe gripping system; and, in at least certain aspects, the gripping system having a body with first and second jaws movably connected thereto and piston/cylinder devices movably interconnected with each jaw for moving the jaws to clamp and then to rotate the pipe.

Abstract: A pipe guide having, in at least certain embodiments, a base, upper extension apparatus pivotably secured to the base and selectively extendable from the base, lower extension apparatus having a first end and a second end, the first end pivotably secured to the upper extension apparatus, the lower extension apparatus selectively extendable with the upper extension apparatus, and pipe holder apparatus connected to the upper extension apparatus.

Abstract: A dual sided elevator for supporting a tubular member in a wellbore operation, the elevator in one aspect having an openable back end and an openable front end, either end openable by using opening apparatus at the front of the elevator; such an elevator with operation apparatus within an elevator body; and/or a top drive system which, in at least certain embodiments, has an apparatus connected below it for breaking connections and such an elevator.

Abstract: A blowout preventer which, in certain aspects, has a main body with a main top, a main bottom, and a main bore therethrough from the main top to the main bottom, at least one bonnet releasably secured to the main body, the at least one bonnet containing movable ram apparatus, and side mount apparatus including at least one side mount secured exteriorly to the main body, the side mount for selectively supporting the at least one bonnet; and, in certain aspects, one or more rollers rotatably connected to the bonnet for facilitating movement of the bonnet on the side mount.
