Abstract
A method of forming a downhole connection between tubular strings includes the step of crimping the tubular strings together. The tubular strings may be positioned in the same wellbore, or the tubular strings may be positioned in different intersecting wellbores during the crimping step. One of the tubular strings may be expanded outwardly within the other tubular string prior to the crimping step.
