Abstract

A downhole tool system which comprises a downhole tool connected for fluid communication to a continuous reel of tubing (1), drill pipe or conventional tubing via a pressure-tight connector (5) for flowing fluids between the formation, the tool and the surface, the downhole tool being in electrical communication with the surface (4).
