Abstract
A downhole releasable tubing connection includes a joint between two tubing strings, wherein one of the two tubing strings is radially expanded and plastically deformed by an expansion device. When the expansion device is moved adjacent to the joint, a mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, separates, breaks, or otherwise provides a release between the two tubing strings. One tubing string and the expansion device can then be removed to the surface of the well bore while the expanded tubing remains installed in the well bore.
