Abstract:
Circulation Subassembly The present invention relates to acirculation subassembly (circsub) for incorporation in a drill pipe. The circsub has a flow through condition in which the circsub allows fluid to flow through a bore of the circsub and does not allow fluid communication between the bore of the circsub and an annulus located outside the drill pipe, a partial bypass condition in which the circsub allows fluid to flow through the bore of the circsub and allows fluid communication between the bore of the circsub and the annulus, and a full bypass condition in which the circsub does not allow fluid to flow through the bore of the circsub and allows fluid communication between the bore of the circsub and the annulus. An actuator is provided to change the circsub between conditions under the control of a controller.

Claim (Index 27):
A valve assembly for controlling flow of fluid through a bore of a piston, the assembly comprising a valve having a first condition and a second condition, an actuation assembly for changing the valve between the first condition and the second condition, the piston, and a sleeve in which the piston is located,\n wherein: the piston is movable to a first position, a second position and a third position relative to the sleeve, the second position being between the first and third positions; when the piston is moved from the second position to the third position the actuation assembly causes the valve to change from the first condition to the second condition; when the piston is moved from the third position to the second position the actuation assembly causes the valve to change from the second condition to the first condition; and the actuation assembly does not change the condition of the valve when piston is moved from the second position to the first position or from the first position to the second position.
