Abstract: An instrumented wiper dart configurable at the wellsite comprising any combination of a sealing member, a sensor sub, an electronics package, and a communication system; wherein the sealing member is cylindrical in shape, releasably coupled to the wiper assembly, and configured to sealingly engage the inner surface of a workstring. The sensor sub is release releasably coupled to the wiper assembly, and includes one or more sensors to measure a property of the wellbore environment. The electronics package is releasably coupled to the wiper assembly, configured to receive one or more data sets from the sensor sub, and transmit one or more data sets to the communication sub. The communication sub is configured to transmit the one or more data sets; and wherein the instrumented wiper plug is displaced down the workstring in response to a volume of fluid pumped from surface.

Abstract: A method for handling pipe includes orienting a pipe having first and second ends so that the second end of the pipe is positioned vertically above the first end, and while the pipe is oriented with the second end positioned vertically above the first end, gripping onto the pipe proximate the first end with a lift jaw assembly that is coupled to a lift arm assembly. The pipe is vertically misaligned at a substantially non-zero misalignment angle relative to the first end of the pipe while gripping the pipe with the lift jaw assembly, wherein vertically misaligning the pipe includes rotating the lift jaw assembly relative to the lift arm assembly.

Abstract: A racking arm assembly is adapted to be mounted on a drill floor of a drilling rig and includes a lift arm assembly having a first arm that is movably coupled to a vertical support column, wherein the lift arm assembly is adapted to be raised and lowered along a vertical length of the vertical support column during a pipe handling operation. A lift jaw assembly is pivotably coupled to a second arm of the lift arm assembly and includes a lift jaw assembly having a lift jaw gripping apparatus that is adapted to grip and fixedly hold a drill pipe stand proximate a pin end of the drill pipe stand during the pipe handling operation. The lift jaw gripping apparatus is further adapted to be rotated relative to the lift arm assembly about a substantially horizontal axis while the lift jaw gripping apparatus is fixedly holding the drill pipe stand.
