Abstract:

Multiple ball launch assemblies comprise a plurality of ball launch pods disposed around an outer wall surface of a housing. The ball launch pods are operatively associated with a flow tube disposed within the housing. An actuator assembly rotates the flow tube to align a first opening in the flow tube with a first ball launch pod so that a first ball is launched into the wellbore. Further rotation of the flow tube aligns subsequent openings in the flow tube with subsequent corresponding ball launch pods so that subsequent balls are launched into the wellbore.

Abstract:

A stinger is stabbed into a bore opening of a downhole tool to communicate fluid from a fluid line to the downhole tool. The stinger body defines a bore that communicates with the bore opening of the tool when the stinger body is installed in the downhole tool. An external surface of the stinger body can seal and lock inside an inside surface of the tool's bore opening when the stinger body is installed therein. The stinger body has a flow passage connected to the fluid line. A stinger port in the external surface of the stinger body is in communication with the flow passage and positions in fluid communication with a tool port inside the tool's bore opening so fluid can be communicated to the downhole tool.
