Abstract
A downhole isolation tool adapted to be converted in the field into any one of a bridge plug, ball drop plug, or a caged ball plug. The components used to assemble the tool, such as the mandrel, slips, and conversion adapters and accessories, are constructed primarily of non-metallic material. Through use of the disclosed isolation tool, drillout time is greatly reduced.
