Abstract
A system including a logging tool that comprises a pulser, and a sensor assembly removably attached the pulser while the logging tool is outside of a wellbore, where the logging tool operates the pulser and causes change of a detectable object in the pulser, wherein the sensor assembly detects change of the detectable object and transmits a signal to a data acquisition computer that is representative of the detected change. A method including operations of removably attaching a sensor assembly to a body of a pulser of a logging tool, detecting operation of the pulser via the sensor assembly, and emulating pressure pulses from the pulser by converting, via the sensor assembly, the detected pulser operation into synthetic pressure pulses.
Claims20
A system for illuminating a rig site, the system comprising:
- a crown deck mounted to a rig at a rig site, the crown deck comprising a handrail forming at least a portion of an outer perimeter of the crown deck;
- a support structure mounted to the crown deck, the support structure comprising a plurality of horizontal supports rigidly attached to a plurality of vertical supports, wherein the plurality of horizontal supports are supported at a vertical elevation above the crown deck by the plurality of vertical supports, with the plurality of vertical supports welded to a top surface of the crown deck;
- and
- a plurality of light fixture assemblies mounted to the plurality of horizontal supports, each of the plurality of light fixture assemblies being rotatable relative to the plurality of horizontal supports between a stowed configuration and a deployed configuration, wherein, in the stowed configuration, the plurality of light fixture assemblies are radially spaced away from, and inwardly of, the outer perimeter of the crown deck, and wherein, in the deployed configuration, the plurality of light fixture assemblies are radially spaced away from, and outwardly of, the outer perimeter of the crown deck.
A method of operating a crown deck lighting system, comprising:
- mounting a support structure of the crown deck lighting system on a crown deck of a rig at a rig site, the crown deck comprising a handrail forming at least a portion of an outer perimeter of the crown deck;
- positioning a plurality of light fixture assemblies of the crown deck lighting system in a deployed configuration in which the plurality of light fixture assemblies are radially spaced away from, and outwardly of, the outer perimeter of the crown deck;
- and
- illuminating the rig site using the plurality of light fixtures positioned in the deployed configuration.
