BALL DROPPING ASSEMBLY AND TECHNIQUE FOR USE IN A WELL
摘要
A technique that is usable with a well includes running string that includes a tool and a flowable object that is held in a retained position within the string downhole in the well. After the string is run downhole in the well, the flowable object is released to permit the object to flow in and subsequently seat in a flow path of the string to impede fluid communication so that the tool may be actuated in response to the impeded fluid communication.
