Abstract:
Switchable cross-over systems, devices, and methods for cementing well walls are provided. A switchable cross-over device includes a tool body, a flow sleeve, and a hydraulic sleeve. The tool body includes a main tool path separable into upper and lower tool paths and an auxiliary chamber containing upper and lower annular ports. The flow sleeve is within the auxiliary chamber and movable into a reverse circulation position by a plug traveling through the main tool path. The hydraulic sleeve is located within the main tool path and mechanically coupled to the flow sleeve. The hydraulic sleeve is movable into a conventional circulation position via pressure within the main tool path acting on the hydraulic sleeve.

Claim (Index 15):
A method of cementing a casing in a wellbore having a wall, comprising:\n setting a packer in an annulus between a cross-over tool and the wellbore wall, wherein the packer separates the annulus into a lower annulus and an upper annulus; placing a plug within a main flow path of the cross-over tool, separating the main tool path into an upper tool path and a lower tool path; moving a flow sleeve of the cross-over tool in a first axial direction into a reverse circulation position, placing the upper tool path in fluid communication with the lower annulus and placing the lower tool path in fluid communication with the upper annulus; and moving a hydraulic sleeve located within the main flow path in the first axial direction, wherein the hydraulic sleeve is mechanically coupled to the flow sleeve.
