June 8, 2013 - PRLog -- With more and more countries put higher importance on environmental protection, oil field service provider companies have to take action on the treatment of the drilling cuttings.

Why we need to treat drilling cuttings:

The two primary sources of solids are chemical additives and formation drill cuttings. Drilling cuttings are contaminants that degrade the performance of the drilling fluid. If the drill cuttings are not separated, they will be ground into smaller and smaller particles that become more difficult to remove from the drilling fluid. Further more, damage the drilling rig.

How to do drilling cuttings separation:

Drilling cuttings are separated by shale shaker, decander, desiler, decanter centrifuge, and collected by screw conveyor or vacuum unit for further separation via vertical cutting dryer & decanter centrifuge.
Most solids can be removed by mechanical means. Small particles are difficult to remove and have a greater effect on drilling fluid property. The particle size of drilling solids incorporated into drilling fluid can range from 1 to 250 microns.

Further treatment of the drilling cuttings

You will have 4 choices for the further treatment after drilling cuttings separation, because you can not dispose them away directly, you may need drill cutting injection, drill cuttings thermal treatment, drill cuttings bio-remediation and drill cuttings solidification and stabilization.

If you have any request, please contact GN Solids Control Co., Ltd. They could offer complete drilling cuttings treatment system.
