Abstract
An isolation tool is provided that includes an upper elastomer, a lower elastomer. The isolation tool when set provides a circumferential flow path between the elastomers. The isolation tool also includes a longitudinal flow path from above the isolation tool to below the isolation tool. The longitudinal flowpath is preferably sufficiently linear that a solid tool may be passed through the longitudinal flowpath from above the isolation tool to below the isolation tool.
