GN Solids Control Equipments Sailing for Russia

It has been years since GN
products became popular among Russian companies, especially for Drilling
companies and oilfield service companies. Not long ago, there are a lot of solids control equipments shipped
to Russian for a drilling rig’s complete solids control line, including shale
shakers, mud cleaner and decanter centrifuges of middle speed and high
speed, the vacuum
degasser, and feeding pumps for desander and desilter
cones for the mud cleaner, the feeding pumps for the decanter centrifuges and
also, the mud mixers and mud guns.

In fact, ever since GN Solids
Control was established years ago, the foreign market has been occupying a
large share of GN Solids Control’s market share. Not only the Russian spoken
countries, but also the Middle East, the Asian countries, the South American
countries and the high standard market including the European countries and
Australia, GN Solids Control has been their first choice among all Chinese
brands.

Why not other brands come from
USA or Europe?

GN Solids Control has been
providing the solids control industry with its high standard international standard
products. GN always believes in Quality first, price second. After becoming the
first API certified solids control manufacturer in China, GN Solids Control has
been certified by HSE, ISO, DNV CE and many other certificates internationally. GN Solids American is
the first USA based solids control company from China, and before the establish
of GN US branch, GN’s products have been accepted by US and Canadian clients
and have been competing with them in their local market. Until now, GN’s
products have been exported to more than 60 countries and regions in the world.

Why choose GN among all Chinese
suppliers in this field?

Of course, quality and reliability
are always most important factors when the end users choose the brand or
supplier. GN Solids Control has a good reputation during the years, and clients
mostly come from introduction by old clients. There is an old Chinese saying
that seeing is believing, at any time, welcome to visit and inspect GN factory
and office near to Beijing airport, the capital of China.

Sources and Sizes of Drill Mud Solids

There are 2 main sources of drill solids
particles are the chemical additives and formal drilling cuttings, the drilling
cuttings are containments that degrade the performance of drilling mud. The
drilling particles will be ground into smaller and smaller and become more and
more difficult to remove from drilling mud if the drilling cuttings that not removed as per guide. Most of the
formal drill solids will be able to be removed by mechanical ways by drill
solids separate equipment and small drill particle will be very difficult to
remove and will have a great effect on drilling mud properties than the very
larger drill solids particles . The solids particle size in drilling mud
incorporated into drill mud will be range from 1 to 250 microns.

The clay, colloidal and bentonizte will be
size between 1 to 5 microns, silt, barites and fine cement dust will be 6 to 44
microns, fine sand will be between 44 to 74 microns, API sand will be 105 to
149 microns, coarse sand can be 500 – 1000 microns, coarse that larger than
2000 microns, there will be colloidal that bellow 2 microns.

Drilling solids particles are the main contaminant
in the drilling mud, so the control of the importance of the good solids
control including increased the penetration rate and reduce mud cost, reduce
water requirement, reduce mixing problem, reduce differential striking, etc.
The drilling solids removal is important to keep drilling mud recycling and re-use.
The
main equipment for drill solids removal are shale shaker , desander, desilter, decanter centrifuge and there will be other
machine assistant to meet separation application including mud tank, centrifugal pump, valve and pipeline.

Shale Shaker for Trenchless Technology

Shale
shaker is designed to separate drilling cuttings above 100 microns by shale shaker screen separation ; there
are 2 sets of vibrator motor installed on shale shaker to supply vibrating
power at 7.0 G force. Different design of drilling
mud shale shaker may have different size and capacity, there
will be 2 or 3 or 4 panels for a single deck shale shaker for install shaker
screen with wedge type or hook type screen installation. All GN oil field shale
shakers are – 1 to 5 degree shaker deck adjusts range and trenchless shale
shaker is +2 degree shaker deck angle.

GNZS752E
mini shale shaker for trenchless
mud system that mud flow no higher than 200 GPM, it is
installed 2 sets of 0.75 kw vibrating motor at 6.5 G force with 2 pc shaker screen
on shaker deck with 1.35 square meters screen area, The screen can be install
20 to 100 mesh screen for drilling cuttings separation between 150 micron to
400 micron separation size. GNZS703E shale shaker is another trenchless
industry shale shaker for mud system that 300 GPM and above , this is a three
deck shale shaker with 3 pc shale shaker screen installed for 500 GPM mud flow
max by 40 mesh shaker screen . It is installed 2 sets of 1.72 kW vibrator motor
to supply 7.0 G force for shaker vibrating.

The
desander and or desilter
cyclones can be installed on any shale shaker to make
it as a mud cleaning for finer size separation , the desander cone can separate
50 microns and above and desilter cone separate 20 microns and above. The
minimum capacity of desander cone is 500 GPM, so we won’t be able to install
desander cone if mud flow required lower than 500 GPM but we can install
desilter cone in that case.

GN HDD System for Australia

In recent days,
GN will deliver to Australia a 500 GPM mud recycling system for HDD.
It is one of GN’s best seller products as the mud recycling system. And 500 GPM
is the most popular configuration among all the available configurations.

As is known to
all, Australian market for the equipments and machines are different from other
markets, because Australia has a even higher standard and more strict rules for
the machine or devices or the environment protection. Some laws and regulations
are even more strict than their peers like USA and European countries.

Although Australia
has such standards, GN Solids Control and GN
Solids Control’s equipments was accepted by Australia. In fact, GN is
the first and only solids control manufacturer who provided to Australia.

Why GN Solids Control?
As a private owned company, GN has no special background or mother company to
be covered with. That’s why the quality is the most important thing. To win a
future and reputation is always what GN does for the past years, and for the coming
years also. Year in and year out, GN has developed from a small company to a
world well known brand.

In domestic
China, there are lots of HDD contractors who buy from GN, and they are giving
repeated orders because they found GN a reliable company with good quality
products. In outside China countries, GN provided to South America, to Asian
countries and to Middle East countries like Saudi Arabia.

When talking
about clients’ countries, we can not let go Saudi Arabia. Before meeting GN
Solids Control, the Saudi Arabia HDD companies only purchased from US brands,
for shakers, desander, desilters and complete
system. But they turned to GN for more cost-effective solutions, maybe at first
they just had a try, because they didn’t believe in some Chinese
manufacturers,. But later GN proved to them that there are high quality Chinese
equipments.

And also, many
HDD rig companies are sourcing from GN to make rig package with GN mud
recycling systems.
