CIPPE is the largest and most professional oilfield
products exhibition and conference in Asia, GN SOLIDS CONTROL always take our
lastest design of solids control equipments and drilling waste management
equipments to CIPPE in Beijing every year in March. This year we also take our
new designed drilling cuttings treatment equipments to Shanghai CIPPE.

The CIPPE oil show general info is as below:

Every year GN solids control will attend international
and domestic oil show as the list below:

CIPPE in Beijing, March

OTC in Houston, May

MIOGE in Moscow, June

Global Petroleum Show in Calgary, June

CIPPE in Shanghai, August

ADIPEC in Abu Dhabi, November

And other oil/ mining/ no-dig industry exhibitions in
Specific country, like Australia, India, Indonesia, USA, Nigeria, Iran, etc.

Our main drilling cuttings treatment equipments showed
at CIPPE including:

(1)  
Hi-G
dryer: It is mainly used for water based drilling mud, shale shaker with high G
force, large screen area, it is the most economic equipment to treat water
based drilling cuttings;

(2)  
Vertical cuttings dryer: mainly used for oil/
synthetic based drilling mud, GN vertical cuttings dryer can be applied for
both water based drilling cuttings and oil based mud. We also have special
designed vertical cuttings dryer for water based mud, welcome to contact with
GN sales for more info.

But most clients will calculate the cost before make a decision,
sometimes vertical cuttings dryer can help them to get very dry solids and less
the cost of TDU, sometimes the cost exceed their effect, they will consider to
use high-G dryer with decanter centrifuge instead.

(3)  
Decanter
centrifuge GNLW363CG, as the most popular and best sold model among all our
centrifuge models, its performance has been field proved by a lot of clients.

GN make all of them as a modular drilling waste
management system, you can choose 1 part, 2 parts or 3 parts, you can also use
part of them according to your rig requirement.

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.

Oil drilling mud dewatering
unit is used to use chemicals to remove the fine solids from the water based
drilling fluids, it has been used in Argentina, Singapore, Nigeria and other
countries in the world.

We
have used the mud dewatering unit for oil sludge waste separation for COSL(China Oilfield Services Limited). Details
pls check http://www.gnsolidscontrol.com/video/oil-sludge-waste-treated-by-gn-centrifuge-with-chemical-for-cosl
. But mostly we only use the mud dewatering unit for water based drilling mud.

GN high speed and variable speed decanter
centrifuge GNLW363CG-VFD and GNLW363CG separation point is 2~5 microns, so it
can remove the solids bigger than 5 microns. For the fastest speed decanter
centrifuge with 3800rpm and 3000G , its separation point is 1~2 microns, which
can separate finer solids, but the working efficiency is not 100%, compared
with mud dewatering unit.

In some cases, the solids particles smaller
than 5 microns need to separated in the water based drilling waste, we will use
dewatering unit by flocculation to make the solids enhanced for easy separation
of the decanter centrifuge.

GN standard dewatering unit including:

(1)    
Powder
Polymer Mixing System

(2)    
Coagulant
Mixing Tank

(3)    
Polymer
and Coagulant Feeding System

(4)    
And
other components

The dewatering unit can be installed inside a
20ft/40ft container together with the decanter centrifuge, with air
conditioner, the purpose is for easy transportation and rain proof, sun proof.
It can be also made on one skid and put it on the ground or mud tank skid, the centrifuge
With VFD control panel are made as a unit with mud tank. The dewatering unit on
top of the tank to save place or on the skid for easy transportation. The latter
way is to save the cost for container, but you must need a sun/rain proof
cover.

To know more details about GN mud dewatering
unit for water based drilling mud, pls contact GN solids control.

Submersible
slurry pump can be used in different applications for oil & gas drilling
solids control system and mud recycling system. The applications are as below:

(1)   
Feeding pump for shale shaker in the mud recycling
system for HDD, water well drilling, CBM.

(2)   
Feeding pump for decanter centrifuge when there is
no enough place for the horizontal screw pump for different industries, oil
drilling , dewatering unit, drilling waste management system.

(3)   
Mixing pump with mixing hopper, because the
submersible slurry pump is vertical installed, which can save the place and
remain the storage capacity, but pls notice the lift and working pressure to
match the venturi hopper.

(4)   
Feeding pump for complete
desander/ desilter unit/ mud cleaning system from the mud pit, remember to
choose the correct model with proper lift, because the flow rate and lift will
loss during the transferring in the long distance. The normal submersible
length is 1.5m, and max 1.8m. If the mud pit or mud tank is very high, and you
need longer submersible length, we will suggest to use hose/pipe for the extra
length, or use the Submerged pump fully under the liquid level.

If there
are small rocks and high solids content in the mud, the submersible slurry pump
is pretty suitable because the impeller is with special wearable hard surface .Centrifugal
pump, screw pump can not be used in such applications, hose pump is another
option for such projects.

Compared
with the horizontal installed pumps, like centrifugal pump, shear pump, screw
pump, the vertical submersible slurry pump required small space and keep the
storage capacity and free of maintenance and reliable performance. There is no
bearing and gland seal between impeller and pump body, so the slurry pump is
maintance-free and high temperature resistance.

GN
solids control has various models of submersible slurry pumps for option.

Water based
drilling mud and oil based drilling fluids are applied together for one land
drilling rig because of the various purpose of the drilling. One package of
drilling waste management or drilling cuttings disposal unit which be used for
both water based drilling cuttings and oil based drilling cuttings are very helpful
for the drilling rigs, it can less the cost for the drilling waste management
system and reduce the space to locate the system, so that you can reduce your total
cost of drilling and ensure to comply with the requirement of environmental
solutions.

Last
week we went to the jobsite of a CNPC drilling rig to check the performance of
our drilling waste management system working with water based drilling
cuttings. The discharged mud from the decanter centrifuge is dry enough and
make the clients satisfied with the result. The system is a modular drilling
waste management system which can be divided into several modulars.

(1)   
Vertical cuttings dryer system :

Including
GNCD930C-VFD vertical cuttings dryer with telescopic skid and the flushing pump
on the skid, the VFD control panel are installed besides the skid, there are a
dry cuttings collection box on the skid.

(2)   
Cuttings transferring system

Including
screw conveyor to transfer the dry material to the top of the vertical cuttings
dryer and cuttings pump to transfer the wet material with much fluids by the
hose to the cuttings dryer. There are a pressure unit on the skid to provide
positive pressure of the VFD control panels.

(3)   
Fluids storage tank

Including
a Cylindrical type tank with mud agitator on top to collect the clean fluids
from the vertical cuttings dryer and a submersible slurry pump to transfer the
fluids to the high-G dryer.

(4)   
High G dryer system

Including
high-G dryer shaker with a catch tank on the bottom to less the solids content
of the fluids discharged from the cuttings dryer and make the decanter
centrifuge working better.

(5)   
Decanter centrifuge system

Including GNLW363CG-VFD decanter centrifuge on the
high telescopic skid and long solids discharge slot, and the clean fluids will
flow back to the solids control system storage tank for reuse.

GN
solids control design and manufacture mud cleaning system for water well
drilling, geothermal drilling, coal bed methane drilling, horizontal
directional drilling, core drilling, Rotary drilling, air drilling, etc. The
purpose to use GN mud cleaning system/ mud recycling system is that:

1 Less
the drilling waste and less the waste disposal cost, it is very important in
some countries which has very strict environment protection laws.

2
Recycle and reuse the drilling fluids, which is very essential in some area
lack of water or very difficult to get new material from the city

3 To
be a responsible company for the society

Depends
on the core diameter and jobsite area, we provide different treating capacity
mud cleaning system. Our standard model including 200gpm, 350gpm, 500gpm,
1000gpm, other customized treating capacity is available to meet your

Regarding
to the fast move solution, GN solids control provide options for trailer mounted mud system, or
skid mounted mud system as well as hydraulic jack up system for fast moving
without lifting by cranes. The hydraulic jack up mud system is very popular
among our clients in Australia, which is cheaper than the trailer mounted mud
system, but do not need a crane when you get ready to move to another place.

Mud
Mixing & Cleaning system produced by GN solids control are available for
sale and rent in Houston, TX. They can be used for piping, crossing and
trenchless civil construction works.

You
have 2 options for GN mud mixing & cleaning system:

Option
#1: Jet mud mixer+ Mud storage tank + GN economy mud cleaning system

The
Mud storage tank can be replaced by a mud pit which is existing owned by the
HDD contractor, it is used to reserve the fluids after mixing which can be
re-used for the project and reserve the fluids discharged from the mud cleaning
system.

The
jet mud mixer is a compact designed skid with mud hopper and mixing pump,
electric control cabinet, pipes. The separated jet mud mixer is more flexible
in the actual utilization.

GN
economy mud cleaning system including 3 standard models, GNMS-200D, GNMS-500D,
GNMS-1000D, all of them with a double deck shale shaker with different numbers
of hydrocyclones.

Option
#2:

GN
self-contained mud cleaning system, this is a multi-function mud system with
mud mixing, mud cleaning, mud storage functions. The advantages for such
self-contained design is for convenient operation, easy moveable, better
separation performance. But with a little higher price compared with the
economy mud cleaning system.

Main
components of the GN premium mud cleaning system:

Mud
tank

Mud
hopper

Shale shaker

Mud cleaner(
desander, desilter, shale shaker, with 2 or 3)

Mud
cleaner feeding pump, Mixing pump

Mud
agitator/ Mud gun

Option
1 is choosed when you already have a mud pit/ storage tank, and mud mixing function
is not so required,and you have space limit in the jobsite, so you need a smart
unit with the good cleaning function.

Option
2 is choosed when you need a multi-function mud system for easy transportation
from one site to another with better performance.

Oil sludge
waste stabilization and solidification unit is a customized system to improve
pollutant retention and give the material obtained a certain structural
durability. Their objective is thus not to achieve a simple cladding of the
contaminated material in an inert matrix, but a complex physical-chemical
process to obtain stabilization and solidification of the pollutants.

Why use stabilization
and solidification unit for oil sludge waste?

Oil sludge
waste come from different ways, like drilling waste storage tank/ pit/ lagoon,
tank bottom cleaning, cuttings separated from drilling waste management system,
solids control system, etc. The oil sludge waste should be proper disposal to
prevent the destroy of environment. The trend of drilling is no-pit drilling in
the future along with the much more strict environmental laws in most of the
countries, which is combination of drilling mud solids control system plus
cuttings transferring system, drilling cuttings treatment system, cuttings
disposal system. GN customized designed cuttings solidification/ stabilization
unit and TDU( thermal desorption unit) are both cuttings disposal methods.

The main
components of GN stabilization/ solidification unit:

1 Absorber conveyor

2 Cement Conveyor

3 Solidsfication Mixer

4 oil
sludge waste collection hopper

5 cement
storage box

6 skid,
handrails, stairs

Working process of GN stabilization/
solidification unit:

（1）Oil
sludge waste collection hopper collects all the drill cuttings & oil sludge
waste, transported to the mixing chamber by the screw conveyor.
2) Cement storage box is keeping cements powder, through the tubular screw
conveyor, powders are sent to the mixer at pre-set capacity.
3) In the same way, absorber is kept in a box, then sent to the mixer by tubular
screw conveyor.
4) The high-shear mixer mixes all the material, and push to the front at the
same time.

If you have questions for the working process and additive
agents for the solidification/ stabilization unit , pls contact with GN solids
control.

The solidification unit and thermal desorption unit,
as one of the most efficient and economic drilling waste disposal method, has
been widely required by drilling waste management companies. GN new developed solidification
unit has been shipped to domestic client for no-pit drilling together with our
hi-G dryer system.

We have developed different customized drilling waste
management system for both water based drilling cuttings and oil based mud
& synthetic based mud.

For example:

(1)  
Vertical cuttings
dryer +decanter centrifuge with telescopic skid and small tank

(2)  
HI-G dryer
shaker+ decanter centrifuge for water based mud with mud tank

But the cuttings discharged from the vertical cuttings
dryer system, decanter centrifuge or hi-G dryer system is still a problem, they
are improper to be re-use, or disposal directly or difficult to be treated or
transported, because of the constituents of the cuttings are not proper for
land application or burial approaches. That is why GN will develop our own solidification
unit and thermal desorption unit to provide our clients a complete drilling
waste disposal solution for no-pit drilling.

The configuration of solidification unit as below:

1 ea cuttings hopper
with 5cbm capacity

1 ea cuttings
transfer screw conveyor with 7.5kw motor

1 ea SS304 steel
Absorber transfer screw conveyor with 1.1kw motor

1 ea SS304 steel
cement transfer screw conveyor with 1.1kw motor

1 ea SS304 Steel
solidification mixer with 2 reverse rotation screw impeller with 11kw motor

Various materials can be added to cuttings to solidify
and stabilize them, to get more details of GN solidification unit, pls contact
our sales.

As the most professional manufacturer of drilling
waste management system, GN solids control has provide a lot of drilling
cuttings treatment system for drilling companies, like CNPC, Sinopec,
especially in 2015, after Chinese government enact new laws for the drilling
waste disposal.

GNZS706E
double deck shale shaker has been widely used for mineral dressing/ ore
separation project, for example, gold recovery. We use different mesh screen to
separate different required ore size, normally the top screen is 3mm opening steel plate screen( or polyurethane material screen for
longer service life) to separate the big solids bigger than 3mm, it can protect
the bottom screen and make the working time longer. The bottom screen is customized,
because different minerals will need to separate different size ore.

GNZS706E double deck shale shaker specifications:

Total screen area 4.66m2( 52.5 ft2), top screen area 2.03m2(24.2ft2)
with 3 panels screen, bottom screen area 2.63 m2(28.3 ft2) with 3 panels screen,
up to 7.0G( adjustable), linear motion shale shaker. The Max treating capacity
is 140m3/h.

Mineral
engineering, mineral processing, or mineral dressing or ore dressing, is the
process of separating commercially valuable minerals from their ores. The simplest sizing process is
screening, or passing the particles to be sized through a screen or number of
screens.

GN solids control also provide a solution to put the hydrocyclones on top of the double deck
shale shaker, as a simple/ compact desanding unit. The working principal is
different with the double deck shale shaker. When worked as a double deck shale
shaker, the material is feeding to the buffer box and flow to the top screen to
separate course ore, and drop down to the bottom screen to separate the required
size.

When
working as a desanding unit with the hydrocyclones, which is used to separate
more fine solids. The material is feeding to the bottom screen to separate
course size then use a centrifugal pump for feeding to the desander cone, to
separate solids bigger than 75 microns, the top screen function for drying the
separated solids size and recycle more fluids.
