In the past few weeks, as the rising of the crude oil price, there was a boom of demands for the oil and gas exploration equipment including the oil and gas solids control systems like the shale shakers and decanter centrifuges. For both the land rigs and offshore projects.

After the separation by solids control shale shakers, the drilling mud will be returned to the mud tank system, but the drilling cuttings are not to be disposed directly because: for one thing, the cuttings for now are too wet and the disposed volume is too large. For the other, the wet cuttings still have quite a lot of drilling mud on them, which are expensive. The most important is about the environment protection purpose, that the wet cuttings with drilling mud on will be pollution for environment. That’s why per laws and regulations in many countries and regions, there must be some drilling waste management equipment to work along with drilling rigs. And along with those drilling boom, GN Drilling Waste management systems becomes more and more popular again. A typical solution for oil based mud drilling cuttings treatment includes following equipment:

1. GNCD930 cuttings dryer. It is like a vertical decanter centrifuge, or more alike to a washing machine’s drying function. It will reduce the oil on cutting to less than 5%. It is especially designed for OBM and SBM. The vertical cuttings dryer is always fed by a screw conveyor which is linked to the other screw conveyor for collecting drilling cuttings from the shale shakers.

2. GNLW363 Decanter centrifuge. It is used for treating the liquid phase after the vertical cuttings dryer, for choosing out the fine particles. Then, after the decanter centrifuge, the drilling fluids are to be returned to the drilling procedure.
This drilling cuttings waste management system is widely used in both land rig jobsites and offshores.
