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.
