  • Dinner Meeting: Technology for Managed Pressure Drilling and New Multiphase Flow Pump Technology

    Wednesday, May 23, 2018, 5:30 PM - 9:00 PM CET
    Tech-Night Dinner Meeting Topic: Technology for Managed Pressure Drilling (Heavelock) and New Multiphase Flow Pump Technology (Fuglesangs) Speaker: Dmitri Gorski (CTO, Heavelock) and Alexander Fuglesang (CEO, Fuglesangs) Date: May 23,   Time: 1730-2100 Venue: Restaurant Olivia Aker Brygge Heavelock ™ – enabling deepwater drilling from floaters in rough weather and with tight pressure margins Below a certain water depth, floating rigs have to be used for drilling. Rig heave (axial rig movement due to waves) has been one of the limiting factors for implementing Managed Pressure Drilling (MPD) techniques in these operations. Rig heave is translated into large downhole pressure variations during connections, when topside heave compensation systems are disabled. This can lead to kicks or damage the reservoir.   Heavelock™ is an autonomous downhole choke valve, able to manipulate mud flow through the drill string, thus cancelling out pressure variations around the drill bit. If implemented, Heavelock™ technology can bring substantial savings to MPD operations from floaters by decreasing Non-Productive Time (NPT) due to Waiting On Weather (WOW) and will thus also lead to considerable reductions in CO 2 footprint of offshore drilling operations. This is especially relevant for Northern Norway with deep waters and rough weather, but also on mature fields with sensitive reservoirs, such as Troll. Heavelock™ technology has its roots at NTNU and the development work is supported by Statoil, Innovation Norway and Research Council of Norway. First tests of a pilot-scale prototype are due to be carried out this spring at Ullriggen in Svavanger.
