1. Material and Equipment
This system is designed to deal with the drill cuttings with high oil content and cannot be treated
by cuttings dryer and decanter centrifuges.
Even on the same drilling platform, there are apparent differences on colors and material
properties of the drilling cuttings.
The oil content on cuttings may vary from 15-40%.
1.1 Mud Material
Drilling Cuttings from offshore drilling platform
Oil based drilling cuttings differs greatly from different formation/location
