Abstract:
A system, method, and tool for controlling fluid flow in a wellbore. The system comprises a tubing string locatable in the wellbore and a crossover tool for enabling reverse circulation in the wellbore. The crossover tool comprises a tool body, a packer assembly, a drag block assembly, and a sleeve. The tool body comprises a bore in fluid communication with the tubing string and a valve located in the bore. The packer assembly is coupled to the tool body and creates a fluid barrier in the annulus formed between the tubing string and the wellbore. The drag block assembly engages the wellbore and resists axial movement. The sleeve is located in the tool body and axially moveable relative to the drag block assembly. The drag block assembly is coupled to the sleeve, and axial movement of the sleeve relative to the drag block assembly rotates the sleeve to control the valve.

Claim (Index 11):
A method of controlling fluid circulation in a wellbore intersecting a subterranean earth formation, wherein a tubing string is located in the wellbore and comprises a bore such that an annulus is formed between the tubing string and the wellbore, comprising:\n delivering fluid through the tubing string bore; resisting axial movement of a body in a first direction on the tubing string relative to a drag block assembly to rotate a sleeve housed in the body in a second direction, wherein the rotational movement of the sleeve in the second direction closes a valve in the bore and diverts the fluid above the valve into a channel in fluid communication with a packer assembly; expanding the packer assembly with the diverted fluid to create a fluid barrier in the annulus, the barrier dividing the annulus into an upper annulus and a lower annulus; moving a piston with the diverted fluid to allow the fluid above the valve to flow from the bore to the lower annulus; returning the diverted fluid from the lower annulus into the tubing string bore; and diverting the fluid in the bore below the closed valve to the upper annulus.
