ABSTRACT:
There is disclosed a method for selective diversion in a deviated wellbore comprising generally perforating the casing with a first group of perforations at the top or bottom abutting an imaginary plane which is substantially in the vertical and extends along the longitudinal axis of the casing and perforating the casing with a second group of perforations circumferentially spaced-away from the plane. Diversion is accomplished by injecting buoyant or non-buoyant diverting agents into the casing and transporting them down the casing in a pathway adjacent to the casing and the imaginary plane. The diverting agents bypass the circumferentially spaced-away perforations and seat in at the perforations at the top or bottom of the casing.
