GNLW363VFD Decanter Centrifuge for barite recovery

Nov. 18, 2012 - PRLog -- To deal with high pressure wells or unstable formations, the density of drilling fluid systems need to be increased via some weighting agent. Barite is a weighting agent mostly used in drilling fluids in oil and gas drilling to suppress high formation pressures and prevent blowouts.

As with all drilling fluids  the fine drilled solids begin to build up,negatively affecting the rheology of the drilling fluid and increasing the fluid density,The challenge is to remove the drill solids from the active system while preserving the barite. It can be accomplished using two centrifuges. One centrifuge is run at a lower speed to remove the barite and the other centrifuge run at a higher speed to remove the drilled solids.  The barite recoverd from the low speed centrifuge is returned to the active system and the liquid fed to the high speed centrifuge for further processing. GNLW363VFD centrifuge with variable speed is a good choice for barite recovery. So far GN have exported over 200 this centrifuge around the world.
