GN decanter
centrifuge can be applied to both oil based mud and invert drilling fluids, and
water based drilling fluids and Synthetic Based mud.

INVERT
drilling fluids are generally used where drilling problems not easily handled
by water-based fluids are expected, or in situations where the invert drilling
fluid is more economical. The major advantage offered by invert fluids is
increased borehole stability.

GN solids control specialized
at customized TBM slurry separation plant with polymer mixing and dosing unit
as a complete system, the polymer mixing unit is applied for polymer flocculant
mixing and feeding to the dewatering centrifuge to get the water as clean as
possible, to separate more fine solids under 5 microns.

TBM
is the short name for Tunneling Boring Machine, Tunnels of less than a metre or
so in diameter are typically done using trenchless construction methods or
horizontal directional drilling rather than TBMs.

We
ever designed a containerized dewatering unit for Tunneling project with the
same application, the main purpose is to get clean water, and dry solids for
disposal. The polymer mixing unit can be installed inside the container
together with GN big bowl decanter centrifuge, by this way, it is convenient
for movement, also it can be located on the skid without standard shipping
container for cooling and easy maintenance, also the cost is much cheaper. We
can make it customized to meet the client’s requirement.

There
are 3 parts in the TBM slurry separation plant: Solids removal unit, polymer
mixing and dosing unit, dewatering unit with dewatering centrifuge. We provide
various options for solids removal unit/ mud cleaning unit, depends on your
required electricity power consumption and budget, we can provide 2-phase
cleaning compact design( double deck shale shaker + desander cone or double
deck shaker + desilter cone) or 3-phase cleaning premium mud cleaning system,
with shale shaker, mud cleaner( shaker, desander cone, desilter cone 3 in 1).

Our
dewatering unit can be applied for both powder polymer and solution polymer,
with pre-humidifyng
system for the powder and dosing system.

We can make the dewatering centrifuge on the
same skid with the dewatering unit or separately. If you are interested in more
details, pls contact GN sales.

shipment, pls contact with GN solids America and visit our stand at OTC.

As
the suddenly dropped down in 2014 and at the beginning of 2015, oilfield
related projects are all slow down, and people stop drilling, service and see
what happened then. Although it settles up to USD60 a barrel recently, many
companies are still in a position to wait and see. At such cost sensitive period,
the drilling contractors, service companies intend to rent or buy solids
control equipments with good quality and competitive price to reduce their
production cost and make profit. GN solids control is a new brand in US market,
but we are not new for solids control industry, our solids control &
drilling waste management system has been working in many fields to over 60
countries in the world, including US, Canada.

We
have separated brochure for vertical cuttings dryer , decanter centrifuge,
drilling waste management system, welcome to visit us at OTC or Houston office
and get more details.

Screw
conveyor is widely used for oil & gas drilling zero discharge drilling
waste management system, the purpose is to collect and move semi-solids
materials, so you can save a lot of labors and more efficient to deal with the
drilling cuttings which should be cleaned and handling before discharge.

Installation
of screw conveyor in the drilling waste management system:

Normally
it is installed horizontally and at a slight incline which is supported by a
customized steel frame according to the distance to the vertical cuttings
dryer, but the angle is normally less than 45 degree. Too incline angle will
influence the moving efficiency of the screw conveyor.

Structure
of Screw conveyor

It
consists of a trough or tube containing either a spiral blade coiled around a
shaft, driven at one end and held at the other, or a “shaftless
spiral”, driven at one end and free at the other. Variable frequency
electric motor can be used to provide a variable speed, which is for the
different drilling cuttings conditions and required moving rate.

The
solids discharge end could be customized design according to the rigsite’s
layout, side discharge or bottom discharge.

GN
solids control standard screw conveyor

There
is hopper opening screw conveyor which is usually used to collect the cuttings
from the shale shaker, desander, desilter, decanter centrifuge. And others are
closed cover screw conveyor, and outside the U-type trough, you can choose with
the frame support or without.

We have screw diameter of 12inch, 14inch,
16inch, 18 inch for option, and the screw conveyor length is divided to
different sections, each section is connected by the bearings, each section is
standard 12ft, you can choose 2 section( 24ft), 3 sections (36ft) or 4
sections(48ft).

Auger
is developed as a traditional drill cuttings transferring method, more and more
people choose cuttings pump or vacuum unit to replace it.

A
lot of waste water is produced together with sludge during the process of
mining exploration. More and more countries turn to or already enact more
strict laws for the drill cuttings/ mine water treatment, to oblige the
drilling contractors to be more cautious of the issue of waste treatment and waste
water drain off.

GN
designed dewatering unit/ solids removal unit/ mud cleaning system is suitable
for such applications. GNLW223 centrifuge is the essential equipment in the
system.

The
compact size( 9 inch bowl diameter, 26inch bowl length), high speed( up to
4500rpm) and separation cut points(up to 2 microns) and high G force ( up to
2500) make this model centrifuge become more and more popular in this industry.
Before submit our proposal, we need the client to do the lab test to figure out
the solids size distribution inside the material, and get the recommendation
for the flocculation proposal and result, then we will analyse the datas and
give the best solution to our clients to meet a wider variety of requirements.

The
separated solids should be taken as dry as it can, and be collected by the
truck and send to construction industry. The clean water is drain back to the river,
lake after waste water treatment center.

Not
only for mine waste water, this dewatering unit/ solids removal unit can be
also applicable with industry waste water treatment, construction waste water,
dredging slurry separation, oilfield waste water treatment, etc all the type of
solids-water separation works, it works together with flocculation and other
chemicals.

If
you are in the project of mine waste water treatment, mine sludge separation or
you are under the pressure of government laws about the drilling cuttings, pls
consult with GN solids control, for America clients pls contact with GN solids
America to get a proposal.

Drilling
mud serve as lubricant that keep the drilling bit operate smooth.  The consequence of drill bit overworked by
temperature heading up will lead to hard work of engine and transmission that
lead to breakdown and halt the whole operation.
It is a very costly operation halt that leads cost of extra ten thousand
of dollars and more. Plus, the drilling fluid is also a very costly lubricant
and to keep the drilling cost under control, solids control machinery is need
for filter the debris that contain in the drilling mud for many times of cycle
of use the drilling mud.  The five
machinery that will completely perform filter the solids from the drilling mud
are shale shaker, vacuum degasser, desander, desilter and
decanter centrifuge.

The filter step goes in below:

Shale
shaker

The
drilling mud feed enter the feeding box of shale
shaker.  The mud
contains various size of the solids return to the ground surface and shale
shaker is filtering the biggest solid by use high G force of shaking.  The box of shale shaker contain panels of
mesh screen that is different number of mesh depend on solids contents analyze
by drilling mud engineer

Vacuum
degasser

. The muds
that return to ground surface not only contain solids but also gas from the
earth core.  This gas that change density
of drilling mud leads result change the viscosity of drilling mud. Vacuum degasser
removes the gas in the drilling mud to keep the mud in balance and continue the
future solids filter process.

Desander

The drilling fluids now that
contain medium size solids enter the liquid feeding pump and enter the
desander, which contain large hydrocyclone(s).  The solids diameter above 40-60um will be
filtered and bottom of desander is pair with shale shaker contain finer mesh
compare with first shale shaker to complete the filtering.  T

Desilter

This machinery’s function of
work is just as same like desander in last step before. It contains multiple
smaller hydrocyclones that can remove solids that measure diameter above
15-40um.  It is also pair with shale
shaker like desander and complete this step of filtering.

Decanter Centrifuge

The drilling fluid feed through
centrifugal pump that feed into decanter centrifuge that rotate in High
speed of G force.  The rotating
bowl will separate solids from the mud and exit in one for solids and other one
is for filtered mud.  The drilling mud
now will feed back to the rig for next cycle of usage.
