Abstract
Apparatus, systems, and methods according to which a launcher defines a central passageway and is adapted to launch an object into the central passageway so that the object enters an oil and gas wellbore. The launcher includes a cylinder rotatable about an axis between first and second angular positions, the cylinder defining a chamber into which the object is loadable when the cylinder is in the first angular position, and from which the loaded object is launchable when the cylinder is in the second angular position. A lubricator is extendable through, and retractable from, the central passageway of the launcher.
