Abstract

A method involves determining an expansion charge able to selectively expand, without perforating or cutting through, a wall of a tubular in a wellbore. The method includes determining conditions in the wellbore, including hydrostatic pressure bearing on the tubular in the wellbore, and a physical characteristic of the tubular. At a second location other than the wellbore, at least one of the conditions determined in the wellbore is reproduced, and a test tubular is provided at the second location. A test expansion charge able to expand, without perforating or cutting through, the wall of the test tubular, is determined based on the determined conditions. The determined test expansion charge is positioned within the test tubular, and is then actuated to expand the wall of the test tubular radially outward, without perforating or cutting through the wall, to form a test protrusion in the wall of the test tubular.
