As is known to all and as is the common practice,
in the drilling rig’s drilling mud circle, more and more solids cuttings should
be separated out from the drilling liquid, so that the drilling liquid could be
used in future procedure.

Per different countries and regions, the
requested standard for the discharged drilling cuttings are different. But what
so ever the world share the same opinion that the discharged waste from the oil
and gas drilling could damage the environment and cause long time ruin of the
farm land and surrounding soil. In some countries where the population is
small, the government lays less strict laws for the discharge, and the drilling
cuttings from the solids
control system could be buried in some non-human living place. But in more
and more countries, the law is strict and only solids control is not enough. Therefore,
many solids control manufacturers are providing more solutions as
drilling cuttings waste management systems, and GN Solids Control, as
always, has the leading place.

1. GN VG-dryer waste management system. It is
a system combined with GNCD930C vertical cuttings dryer and GNLW363 Decanter
Centrifuge, used for further treating the drilling cuttings discharged from the shale
shaker, mud cleaner and solids control centrifuge of the solids control
system. Per jobsite test, only the vertical cuttings dryer, the OOC result of
GN Vertical
Cuttings Dryer can be below 5%, and the liquid phase could be better
treated by the decanter centrifuge. For both Vertical cuttings dryer and the
decanter centrifuge, GN has fixed speed and vfd controlled for option.

2. GN Solidification Unit, it is a new
design of GN Solids Control, for feeding the need of some clients whose local
laws are more strict than others. In their countries, the solids from VG-dryer
system are not allowed to discharged directly. Solidification unit could make
the solids cuttings to form like concrete and suitable for other applications.
This is mostly for WBM.

3. GN TDU unit, also new product of GN
Solids Control and mostly used for final treatment of OBM.

GN Solids Control sell a series of solids
control equipment and drilling waste management equipment including mud agitator ,vertical
cuttings dryer , shale shaker , screw conveyor , screw pump , oilfield shale

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

GN solids control develop new
products Thermal Desorption Unit as the further treatment equipments for GN
standard vertical cuttings dryer waste management system.

According to our clients
feedback after using GN drilling waste management system, the oil content in
the cuttings is below 5% , in some countries, the parameter is acceptable for
environmental laws, but in some other country, they have extreme strict environmental
protection that they need the “number” under 1%. So they need the thermal
desorption unit to do the further treatment. But because of the high price of
the TDU, most clients can only rent it.

GN thermal desorption unit can
match our own drilling waste management system, also it can match other brand
vertical cuttings dryers. Same as the goods solids control system can reduce
the drilling waste, so the drilling waste management system working performance
will be improved; the goods drilling waste management system( or vertical
cuttings dryer system) can reduce the oil content in the cuttings as much as it
can, so the thermal desorption unit will work better. GN vertical cuttings
dryer’s data is around 3.77%. If the cuttings dryer did not works well, you
will have to pay more in the further treatment, and the TDU result may not
match the environmental requirement.

TDU will be used only for oil
based drilling cuttings treatment, for water based cuttings, GN high-G dryer
shaker and high speed decanter centrifuge will separate the solids very dry and
ship them by truck, and recycle the fluids as much as possible. We make them
into modular unit and make them combination in a system to meet your different
requirement for both water based and oil based drill cuttings.

To get the brochure of GN
thermal desorption unit , solidification unit, drilling waste management
system, pls contact GN solids America in Houston, 6710 windfern rd, TX77040.

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.

Containerized drilling waste management system is
special designed by GN solids control for cold weather and other purpose. We
have made a lot of sets of drilling waste management system customized and
installed them inside the standard 40ft container. The purpose is as below:

1 easy transportation, bulk cargo shipment is always
not so flexible on freight line arrangement. Our system can be shipped as a
container through our handlings.

2 prevent of the cold weather: Especially in Russia,
our system can work when the temperature lower to -40°,
there is special insulation inside the container to keep the equipments warm.

3 There is air conditioner and fan which is for the
operation in summer.

4 Door and windows are opened for operation,
maintenance, and radiating.

5 The top proof cover is with function of sun proof,
rain proof and snow proof and other water proof.

Except for drilling waste management system, we also
design dewatering unit with decanter centrifuge inside 20ft or 40ft containers.
The purpose for the container is more or less similar with the above case. But
this is a high configuration design, to save cost, we can remove the container,
and put the dewatering unit on the centrifuge skid or on the tank directly,
with sun proof cover on top.

We also designed container sized mud tanks, both
utilized in mud recycling system, solids control system and liquid mud plant.
It is suitable for standard container trailer transportation. Especially in
liquid mud plant, for small footprint purpose, the standard container sized
tanks can be stacked for 2 or 3 layers to save place and save money.

Recently we shipped the 9^th containerized
drilling waste management system with screw conveyors, decanter centrifuges,
screw pumps to Russia, For more technical details, pls check with GN solids
