Although the price for crude oil is dropping form an extremely high place to anunexpected low place, the global demand for the oil never ceases. But as longas the drilling projects are done everywhere in the world, the environment
effects are shown more and more clearly.

Now more and more countries are issuing
laws and regulations for protecting the environment. Before, in some places,
after drilling, the drilling cuttings could be buried in a remote place, but
now, nothing is allowed to be discharged without further treating. In some countries,
any drilling work is allowed without seeing an existing waste management
solution or system.

Depending on different drilling fluids, the
waste management system is a bit different. Normally, there is WBM and OBM.

1.      Complete WBM waste management system.

A complete WBM waste management system is
combined by 2 sections. First section, standard waste management system
includes a drying shaker with a high G force and a high speed decanter
centrifuge.  Second section is further
treatment, a dewatering unit to flocculate the fine particles into larger ones
in order to be treated by a high speed decanter centrifuge, here, the
centrifuge may be same as the former one, but this one is regarded as
dewatering centrifuge. This whole system is called as zero discharge drilling
system.

2.      Waste
management system for OBM

The complete waste management system for
OBM could also be regarded as 2 sections, the standard one and further one. The
standard waste management system for OBM is combined by a vertical cuttings
dryer and a high speed centrifuge.  After first stage, the further stage is to
make the cuttings more compact and into solid before discharge.

GN Solids Control is most famous China
brand for solids control and waste management systems and equipments. They are
producing high speed centrifuges for waste management, and their products are
of high cost-effectiveness. And also, GN Solids Control is first Chinese
company who designed the vertical cuttings dryer years
ago. Now their vertical cuttings dryer reached the 4th generation, which could provide
more applications suitable for not only OBM and SBM, but also WBM.

If you need to know more about GN and GN
products, you are welcome to attend the coming CIPPE in Beijing, Capital of
China.
