A specialized wireline-conveyed collet baffle, adapted for use with a conveying tool, setting tool, and explosive charges, for perforating and fracking a wellbore. The collet baffle like prior art baffles possesses an annular ring for engaging a circumferential annular groove in a casing, but unlike prior art baffles possesses an inner annular hollow ring member which may be actuated by a push rod of a setting tool and slidably repositioned when such annular ring underlies and is engaged with the circumferential groove on a casing sub, thereby retaining the collet baffle in place in the casing string when the conveying tool, setting tool, and explosive charges are subsequently re-positioned uphole. An adapter tool for coupling the collet baffle to a conventional setting tool, a wireline system employing the specialized collet baffle and adapter tool, and a method for perforating and fracking a wellbore are further disclosed.
