Title:

WELL BORE TOOL WITH BALL SEAT ASSEMBLY

Document Type and Number:

WIPO Patent Application WO/2014/210390

Kind Code:

A3

Abstract:

Tools for a well tubular comprising a ball seat assembly. The ball seat assembly comprises first and second bail seats. The first ball seat is adapted to receive a ball deployed into the tool, transition to a second state and release the ball. The first hall seat is operatively engaged with the second ball seat such that as it transitions to its second state it causes the second ball seat to transition from a first state of increased clearance to a second state having reduced clearance. The second seat then is adapted to receive the ball after it is released by the first seat. The second ball seat is adapted to actuate the tool, transition to a third state, and release the ball. The clearance through the second ball seat in its second state is less than the clearance through the first ball seat in its first state.
