The drilling package HoD combines continuous circulation, high resolution flow rate monitoring and anti-friction device to obtain highest HSE standard and enhanced drilling performance.
The HoD Continuous Circulation System is designed to maintain circulation of drilling in the wellbore even while adding or removing drill pipe stands. Managing downhole pressure and drilling through very narrow pore/fracture pressure windows are possible thanks to the continuous dialogue with the bottom hole and the constant presence of a double barrier in the well: the mud circulation and the BOPs. At the same time, the continuous cuttings transport and the better mud properties optimization ensure a significant improvement in ROP and NPT, with very short connection time.
The HoD Continuous Circulation System is comprised of special subs on top of drill pipe stands or integrated directly with drill pipe tool joints, a fully automated Clamp and a dedicated manifold. Everything is designed to be easily integrated with other rig equipment and to allow personnel to move away from the rig floor and mange operation remotely.
All this allows to reach targets in all challenging operation conditions, in particularly in HP/HT wells, extended reach wells (ERD) and in deepwater, with a drastic reduction of time and project costs and with an early field production.
