Recently GN
solids control
shipped 2 shale shakers and 2 mud cleaners for Hongkong clients,
the color is customized silver grey color which is different with our normal
green color, we can provide customized color, design, brand and nameplate for
client’s special requirement.

The desander cone, desilter cone and bottom shale shaker combination as
mud cleaner, compared with single desander, desilter , the mud cleaner with
bottom shaker which can collect useful drilling fluids and make the discharged
solids drier, and the footprint is smaller. Sometimes when shale shaker is not
working, it can be also used as back up shaker.

With different quantity desander cone and desilter cone, the mud cleaner
has different treating capacity, 1S8N with 1 of 10 inch desander cone with 8 of
4 inch desialter cone, the treating capacity is 500gpm, 2S12N with 2 @ 10 inch
desander cones and 12 @ 4 inch desilter cone with treating capacity about
1000gpm,  3S16N with 3 @ 10 inch cone(sometimes
with 2 of 12 inch desander cone) and 16pcs of 4 inch desilter cone, the
treating capacity is 1500gpm. The Hongkong client bought 2 units of 1500gpm
capacity mud cleaner with 3 desander cone, 16 desilter cones.

The shale shaker and mud cleaner bottom shaker are the same model, and
use the same size shaker screens, so the clients do not have to make different
size screens for inventory. Our most sold shale shaker models including GNZS703
& GNZS594, the former model with 3 panels screens of size 700x1250mm, the
latter model with 4 panels screens of size 585x1165mm.

Right now we have several units of GNZS594E-HB shale shaker and mud
cleaners in stock of Houston branch, welcome to visit GN solids America. With the
US Martin brand vibration motor, good quality and reliable performance is
assured.

This week GN solids control shipped
one set of solids control system to Asia country,

Including one set of high G force linear motion
shale shaker
GNZS594E-HB, 2 sets of variable speed decanter centrifuge
GNLW363CG-VFD with 2 sets of feeding pump, 1 unit of catch tank. It is not
traditional solids control system for oil & gas drilling, like GN standard
& customized designed solids control system for drilling rigs from 250HP to
3000HP. The traditional solids control system will at least include 2 or 3 or 4
sets of shale shaker, with
desander
, desilter or mud cleaner, vacuum degasser, the
centrifuge is as an option, also the mud mixing tank & storage tank. The
purpose to use 2 units of VFD decanter centrifuge is to separate the fine
solids from the drilling fluids and get the water be re-used for drilling.

GN solids control is specialized in design customized solids control
system for different models drilling rigs, both for oil & gas drilling and
non-oil industry drilling, like water well drilling, no-dig drilling. In recent
years, our main products changed to drilling
waste management system
/ equipments which combined with solids control
system as zero-discharge system or called pitless drilling cuttings treatment
system. The function of pitless system is to prevent the earth from hazardous
drilling waste, especially to protect the under-ground water and earth. The
traditional oil drilling will need to dig a hole under the ground to remain the
drilling waste, and use the truck to transfer the drilling cuttings to the
drilling waste treatment facility. It will damage the environment in 2 aspects:
1) it may pollute the underground water & earth 2) it may spray outside
from the truck during shipment and pollute the farmer’s earth nearby 3) it will
increase the drilling waste management cost, so increase the total drilling
cost and reduce the profit.

To get more information about GN solids
control system
and pitless drilling mud system, pls contact GN solids sales.

GN vertical cuttings dryer can be used for both water
based mud and oil based mud/ or SBM. The maintenance cost is one of the main
concern for mud service company or waste service company, they are all looking
for a cost effect dryer for the drilling
waste management
compared with US brand cuttings dryer or ship the waste to
drilling waste management companies.

The main spare parts for vertical
cuttings dryer
are as below, most of the maintenance cost is from these
spare parts:

(1)  
Screen
basket, the screen basket and screen frame are separated components and they
are balanced separately. The screen basket scraper is installed to prevent the
discharged fluids from blocked on the screens, sometimes the solids content is
very high, it is not easy to get down from the screens. Based on different
drilling cuttings conditions, the replacement period will be different for the
screens, pls check with GN sales engineer team for the required quantity in one
year.

(2)  
Flites
& Cone Rotor Assembly, the 8 flites are fixed on the rotor assembly, you
need to replace it completely. The flights are used to prevent cuttings
blocking the screens and scraping the mud inside the screens.

(3)  
Bearings
replace time based on actual working time.

(4)  
Bell
jar with scraper, the scrapers are used for solids discharge scraping.

(5)  
Liquid
discharge ring, it is not easy to be damaged normally, 1 set is required as
back up.

With flushing pump and air knife to provide
pressurized cleaning, that is why GN cuttings dryer can be used for both WBM
and OBM. We have 2 units of vertical cuttings dryer and other equipment include vacuum degasser,
decanter centrifuge, shale shaker,mud agitator, desander ,etc. stocked
in Houston warehouse, 6710 windfern road, Houston, TX 77040, USA. GN keeps research and develop the best technology to manufacture top
quality equipment for our clients. Cuttings
solidification unit
is the new design of GN Solids Control.Welcome to check our website to know more info from GN

Decanter centrifuge is seldom
used for horizontal directional drilling because of the high cost and
separation factor. Only when the fine solids accumulated on the mud recycling
system and the desilter cone can not separate them out, then the recycled mud
can not be used for drilling unless the fine solids (smaller than 15 microns)
could be reduced. GN low speed/ middle speed decanter centrifuge GNLW452
centrifuge should be used by such situation.

GN has shipped 4 sets of
1000gpm mud recycling system with 2 units of GNLW452 decanter centrifuges for
CPP(China Petroleum Pipeline Bureau) for their crossing project. Totally 4 sets
of desander mud cleaner with 2 10inch desander cone and double deck shale
shaker
GNZS705, 4 sets of desilter mud cleaner with 10pcs 4inch desilter cones
with double deck shale shaker, 8 sets of GNLW452 decanter centrifuge with 18inch
bowl diameter, 1800rpm speed, 8 sets of centrifugal pumps to feed for the
desander, desilter, 8 sets of feeding pump for the decanter centrifuges. 8 sets
of 20ft container to install the equipments on it and with storage capacity.

This is not the first order
from CPP, they start to buy mud recycling system for HDD since 2010, and until
now they already bought 30 sets of drilling mud cleaning system from GN solids
control.

The function of the decanter
centrifuge
in this system is not to separate all the fine solids under 15
microns, the purpose is to reduce the fine solids content in the recycled
fluids so it can be re-used for the drilling. So the centrifuge capacity do not
have to equal with the solids control mud cleaner, it is not always running, we
will open it according to the mud conditions.

Not only for HDD mud recycling
system
, the same design could be used for tailings treatment of mining, oil
drilling. Welcome to contact GN solids control for more info.

As one of the
lead manufacturer of decanter centrifuge screw conveyor in China and with
branch office in Houston , GN solids control produce different models of
decanter centrifuge over 250 units every year.

The material of the whole screw conveyor is stainless
steel 316L, the flight of the screw conveyor is protected by the tungsten
carbide tiles over 4mm thickness, the material is YG8 with hardness factor
89HRC. The main bowl is made of duplex stainless steel 2205, which is better
than SS316 and SS304. The other bowl assy is made of SS316L. This is the basic
configuration of GN premium decanter centrifuge. The opening of the screw
conveyor can increase the treating capacity and make the performance better. The
tungsten carbide tiles are interchangeable when the old ones are damaged.

Even GN economic configuration decanter centrifuge,
the flight is protected by special ceramics tiles. The other parts are with
same material with premium decanter centrifuge.

The screw conveyor inside the centrifuge bowl is the
essential parts for a decanter centrifuge, the design and protection of the
screw conveyor will directly influence the centrifuge’s performance. The bowl
assy is the main and most important part of decanter centrifuge.

Expect of decanter centrifuge screw conveyor, GN
solids control also produce screw for the auger. Screw conveyor/auger is common equipment to convey powder, granular and
small lumpy materials. All bearing operate under dusty conditions. Therefore,
reasonable operation and maintenance is vitally important. The following
paragraphs describe main requirements of operation and maintenance.

The auger can be used to transfer the drilling
cuttings from the solids control system cuttings collection box to the vertical
cuttings dryer
, and as collection auger for the solids control system shale
shaker, desander, desilter, decanter centrifuge, and transfer the dry solids
discharged from vertical cuttings dryer.

Now we have 20 units of decanter centrifuge in stock,
welcome to contact with GN solids control.
