To some degree, workovers are classified on the basis of the reasons for them (discussed earlier). Another way to describe types of workovers is to divide them into (1) jobs performed primarily to influence the reservoir and (2) jobs applied to the wellbore (including the cement) and its associated equipment. Workovers done primarily to influence the reservoir can be subdivided into (1) work done for the zone already open and (2) work done to shut off the existing zone in favor of opening a new zone, termed a ''recompletion''.
