   Drilling Waste Management Unit to Western Africa

    How exciting it is. Hebei GN Solids Control Co., Ltd will has its drilling waste management unit delivered to Western Africa.

    Generally, solids control system is designed to clean and recollect waste drilling by removing the useless solids. A complete line of equipment would be installed ,such as shale shakers, desander ,desilter( mud cleaner with the combination of desander and desilter is optional), and decanter centrifuge. In addition, for environmental reasons, solids which are separated from used drilling mud is not allowed to directly dump. To make a solution, drilling waste management is now applied.Drilling waste after uid content).

                                                                     Drilling Waste Management

    Two ways are commonly seen to treat and recycle drilling waste: online drilling cuttings treatment and base mud recycling; offline wasted sludge disposal. Online treating is relatively easier and cheaper, the drilling cutting is directly transfer to vertical cutting dryer through the auger after discharged from shale shaker, while offline management will require more complicated processes for a satisfactory results. GN’s wast management unit belongs to the online treatment.

    The equipment list i ncludes:  one set of vertical cutting dryer,  one set of Netzsch Brand NEMO pump, one set of mounting decanter centrifuge, one set of vertical slurry pump, one set of oilfield 3 runner design skid ,  one set of accessories and electrical control panel system.

                                                                                                                                     .Vertical Cutting Dryer

    GN Solids Control is a leading manufacturer of solids control system and equipment in China, GN’s decanter centrifuge and vertical cutting dryer have been used in many waste management project. And, in such a beautiful fall, one GN’s drilling waste management unit is ready to go west Africa where she will service all through her life.

Solids Control Equipment Exported to Indonesia

on . Posted in News

Indonesia once is the unique OPEC nations from Asia. The proven oil reserves, ranking 20th in the world; the proven gas reserves, ranking 7th in the world. With more and more China-Indonesia cooperation in oil gas exploration & drilling, oilfield equipment supply, crude oil imports & exports, Indonesia company focus on drilling rigs, solids control equipment, mud pump with super quality and competitive price.

GN Solids Control as the 1st API certified solids control equipment private company, is the first private company to enter Indonesia market. After that, more and more Indonesia customer ( Big customers like PDSI,Apexindo,Bermindo etc) shift to GN Solids Control Equipment and gradually to use less US brand solids control equipment with highly cost.

Recently, GN is ready to delivery one unit 1000gpm mud system to Indonesia. The mud system is used for one unit 750hp workover rig. The mud system equipped with equipment as below:

  • Two unit drilling fluids shale shaker with 3 panel shaker screen & 2 pcs OLI brand vibration motor;
  • One unit drilling fluids mud cleaner with 2 pcs desander cones & 12 pcs desilter cones & one unit deck shaker with 3 panel shaker screen.
  • One unit drilling fluids vacuum degasser with self-contained unit & level sensor to protect over suction of drilling fluids.
  • One unit mud tank with all accessories included. Eg. pipelines, handrails, walkways, ladders, valves, clean gates...

solids control equipment

Except for Solids Control Equipment, GN also exported drilling waste management equipment to Indonesia national oil company, Pertamina. The equipment including Hi-G dryer shaker as 1st step drilling cuttings drying pocess equipment, high speed decanter centrifuge as 2nd step drilling cuttings drying process equipment.

dewatering centrifuge

After the drilling cuttings dried by Hi-G dryer & decanter centrifuge, the usable drilling fluids can be recovered and go back to solids control system. If the drilling finish and no need back to mud circulation, flocculent unit and dewatering centrifuge is necessary for further treatment. GN can also offer the dewatering unit with dewatering centrifuge.

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. Recently, one Thailand customer bought one set 500gpm mud system to match with TBM machine for Tunnel shield project. Follow to read more about this case.

The 500gpm Mud System Technical Parameters

  • One unit of double deck 6 panel shale shaker, GNZS706 with upside 3 panel coarse mesh shaker screen (2mm) and downside 3 panel fine mesh shaker screen ( 40mesh). The upside shaker screen area 2cbm; the downside shaker screen area 2.6cbm.
  • One unit of mud cleaner or mud conditioner, GNZJ703-8N with 3 panel deck shaker and 8 pcs X 4inch desilter cones. The separation points 25-40 microns.
  • One unit of centrifugal pump (37kw) for feeding desilter cones, the feeding pressure should reach 0.25-0.4Mpa; GN centrifugal pump is interchangeable with NOV mission pump. GN can also offer complete range of spare parts for NOV mission pump.
  • Two unit of mud agitator (11kw) to suspend and mix the drilling fluids.
  • Two unit of mud gun (2inch, fixed installation type) to working together with mud agitator.
  • One unit of mud tank with 4 compartments.
  • One unit of separate mud mixing unit, GN jet mud mixer with one mud hopper and one centrifugal pump (37kw). This unit can help supplement drilling mud to the system or add necessary chemicals or water.

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.
