drilling waste

Many people get problems after found drilling cuttings from shale shaker is not dryer enough and they need dry them to delivery as per law. What you can do to dry oil base mud drilling cuttings?

GN Designed and build drilling waste management system for oil base mud cuttings and can supply a complete line of it to offer a solution for you.

Main Points Of GN Drilling Waste Management System

  1. Buyyer need supply (Or buy from us) 2 augers to feed vertical cuttings dryer by drilling cuttings out of shaker from solids control system
  2. Vertical cuttings dryer will process cuttings and dryer cuttings with oil no more than 5%
  3. Dry cuttings will be collected by another auger and delivery to cuttings storage
  4. Fluids from vertical cuttings dryer will drop to a small holding tank
  5. A screw pump will collect oil from holding tank to feeding decanter centrifuge for recycling
  6. Solids from decanter centrifuge will be collected by an auger and to a cuttings box
  7. Clean fluids after centrifuge will be guide into solids control mud tank for re-use
  8. Auto control of screw pump will help a lot cause it’s not working continously, this will help save labour and mistake
  9. High speed centrifuge is requried to separate solids 2-5 micron with 3200RPM speed
  10. Holding tank size no need to be very big cause fluids after vertical cuttings dryer not so much

GN Solids build waste base drilling cuttings dryer system also, please contact GN freely

Cuttings re-injection is an in situ method for the disposal of driling cuttings and other drilling wastes into a sub-surface stratum

Drill cuttings are slurrified with water and ground down to a pre-determined partical size. The partical size is achieved by passing through a shaker screen. Slurry of hte correct partical size and physical properties is injected via a pump, which is typically of a triplex design, into the well head at a given pressure and down into the pre-detaimined sub-surface injection zone.

Cuttings blowing pump ( CBP ) blows drill cuttings and centrifuge waste from a collection point on the rig to a temporary bulk storage tank on the rig. Benefits of CBP

1) High capacity in excess of 35MT per hour

2) Allows cuttings to be blown straight to a boat

3) Reduces exposure to drilling wastes on the rig

4) Carane lifts are minimised, reducing the risks associated with lifting numerous drilling waste containers from the rig to a boat
