Abstract
A downhole releasable tubular 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 threaded connection mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, thereby decoupling the tubing strings.
