Abstract
An energetics device is employed to create an outwardly directed pressure wave at a selected depth within a wellbore tubular cemented into a wellbore. The pressure wave causes the wellbore tubular to plastically deform at the selected depth. This locally expands the wellbore tubular at the selected depth, whereby a circumferential recess is created into an inner surface of the wellbore tubular and whereby the outer surface of the wellbore tubular is forced into the surrounding cement sheath at the selected depth. Microcavities and/or micro annuli in the impacted zone may be sealed as a result.
