Tunnel Shield Project 500gpm Mud System to Thailand

on . Posted in News

Shield Method is one fully mechanized underground construction Method. The shield machine will be pushed forward, the surrounding rock will be supported by shield shell and segment. At the same time, excavation of soil will be conducted at the front of the excavation face by cutting device; the soil will be carried out by unearthed machiner. After that, the shield machine will be pushed forward again by jack and assembling precast concrete segment, this is the general formation process of tunnel structure.

Tunnel Boring Machine (short as TBM) and Mud system is indispensable for tunnel shield project. TBM as main equipment, mud system as auxiliary equipment to make the TBM working in a high effeciency way.

VFD decanter centrifuge & Hi G cuttings dryer in Indonesia

on . Posted in News

GN has provided a customized solution to handle the drilled cuttings off the shakers for a drilling project from Pertanima, an Indonesian state-owned oil and natural gas corporation. GN after-sales engineers went there for the field service.

The solution mainly consists of a Hi G cuttings dryer shaker and a Variable Speed decanter centrifuge to treat the water based drilling fluids waste.

GNZS853 Hi G cuttings dryer vibration force can be up to 8.0 G.  With a screen area of 3.2 square meters, the cuttings can stay longer on the screen for trapping the solids and the cuttings off it are dry enough for transportation.

For oil based mud (OBM), we have vertical cuttings dryer to dry the drilled solids and big bowl oilfield decanter centrifuge for bentonite recovery.
