ABSTRACT:
A drilling system for use in a well bore consists of a drill string, an electrically powerable pump (8), a connector (16) for supporting the pump (8) including a through bore (32) through which fluid can flow, and a power cable (15) to provide power to the electrically powerable pump. The cuttings are pumped up through the drillpipe (3). The drill bit (4) may also be powered by the pump. Part of the cable is disposed externally to the drill string where new pipe sections are added, before passing into the drill string through a cross-over means (40) further down the drillpipe to connect to the electrically powerable pump.
