Trechless Mud Recycling System Will Be At
No Dig Shown

GN Solids design and build a series of mud
recycling system for trenchless technology , amount all of the designs , GNMS
-200G , GNMS -350G , GNMS -500B , GNMS -500G , GNMS -500GL are the most popular
options depending on different drilling conditions . GN Solids will bring one
set GNMS -200G mud recycling system to the show with max 200 GPM mud capacity
with a double deck shale shaker , it is a two phase cleaning mud system with
shale shaker and desilter cyclones . Mixing application is available with a
small mixing pump and mixing hopper , mud tank size 4m x 2m x 1.3m devided into
2 compartment with sand trap and mixing compartment , the 2 sets of centrifugal
pump sit on tank skid .

GN Solids normally show different models of
mud recycling system every time , we showed 500 GPM mud recycling system at
year 2011 with a 3 phased cleaning by shale shaker , desander , desilter and
mixer with jack legs for fast moving . Other than GN standard mud recycling
system, we build customized mud recycling system also , please contact GN
Solids freely .

Hebei GN Solids Control Co., Ltd
has many years of experiences in solids control field for oil and gas drilling
and has developed fast and stable in a few years. Now it has the ability to
design and manufacture mud recycling system for HDD drilling, CBM drilling,
geothermal drilling; desander unit for bore piling, TBM;
solids removal unit for other kinds of drillings. Recently GN delivered 2 sets
of solids removal unit to a South America drilling contractor. South America is
one of GN’s main markets where many sets of GN decanter centrifuge are
operating such as Brazil, Argentina.

 The solids removal unit has 2 phase
treating machines. The 1 phase is GNZS752 shale shaker with 2 panel screen which renders a
capacity of 200GPM. It is used to remove coarse solids to lower the abrasion
for the second phase treating machine, and also to enhance the treating
capacity of second phase machine. The 2 phase machine is GNLW223 decanter centrifuge with
small bowl but high speed to separate fine solids out.  Also there is mud mixing device. After
treated by the decanter centrifuge, the mud will be clean enough to be mixed
with chemical so that it can return to the drilling rig for the recycling
usage.

 With the support of GN Solids Control
Argentina service support center, and the facility in Houston, Texas, GN Solids
Control is able to provide South and North America market client with fast
delivery and fast response for after sales services. Normally GN will recommend
the operators to keep a minimum stock of spare parts for its regular
operations. For the first time commissioning of the solids removal unit is free
of Charge from GN Solids Control within limited time, clients only need to
offer the flight tickets and accommodations. During the commissioning, GN Engineers
will also train up the clients engineers for the solids removal unit operation
and maintenance.

Hebei GN Solids Control Co., Ltd is the top
manufacturer of solids control equipment in China. It is the first API
certified, and until now it has been certified by DNV CE, and Russia TR&TC.
With about a decade’s fast and stable development, Hebei GN Solids Control Co.,
Ltd has exported to over 60 countries with a famous and international brand GN
Solids Control achieved which targets the middle and high end market. In 2015,
GN Solids Control set up the first USA-based solids control company owned by a
China’s manufacture in Houston. Starting from solids control equipment for oil
and gas drilling, GN Solids Control already extended the application to other
kinds of drilling project such as HDD, CBM, Tunneling, Bored Piling, Water well
drilling, Geothermal drilling and has designed the standard models of economic
desander unit mainly for bore piling and mud systems for HDD, CBM, and
Tunneling.

Similarly, the treating equipment in both
desander unit and mud system are generally shakers and cones. While, the
quantity of the treating equipment depend on the treating capacity required by
the customer. Different size of cones can separate different size of solids.
The 10’’ cones usually separates solids over 0 microns, the 4’’ cones usually
separates solids over 20 microns. The different thing is that the mud system
includes mud mixing device.

GN drilling mud shale shaker is the primary solids control
equipment, normally used to separate solids upper 100 microns depends on the
shaker screen mesh it used.The mud cleaner is a combination of desander and
desilter, with a downstream shale shaker for drying solids under the
hydrocylones.The desander gives separation of upper 40 microns sands, and the 4
inch desilter separate silts upper of 20 microns. So the mud cleaner normally
work as the secondary and third phased solids control for drilling mud.

Where is the drilling mud used, where is
the need for mud cleaning and recollecting unit. Starting from solids
control system for oil and gas drilling, Hebei GN Solids Control Co.,
Ltd has extend its product line to mud cleaning unit for other kinds of
drilling such as HDD, CBM water well drilling, geothermal drilling, tunneling
and bored piling. Unit now, over 30 sets of mud cleaning unit are delivered to
Australia and New Zealand for HDD trenchless project. So what is HDD drilling?

The full name for HDD is Horizontal
Directional Drilling, commonly known as directional boring with trenchless
method to install underground pipes, conduits and cables in a shallow arc along
a prescribed bore path by using a surface-launched drilling rig, with minimal
impact on the surrounding area. When the trenching or excavating can’t be
carried out because of the environmental protection to the landscapes, road and
river, the HDD is the used. Installation lengths up to 2000 m have
been completed, and diameters up to 1200 mm have been installed in
shorter runs. While when there are voids in the rock or incomplete layers of
rock, directional boring is not practical.

In the mud cleaning system for HDD, there are always 2 or 3 stages
treating machine with a mud mixing device. The first stage treatment equipment
is shale shaker which removes coarse solids out; the second stage treatment
equipment is 10’’ desander cyclone to separate
solids over 40 microns; the third stage treatment equipment is 4’’ desilter cyclone to separate solids over 25 microns. After
the treatment, the clean mud will be added some chemicals and mixed for usage.
Later, GN will bring its 350 gpm mud system to attend a show in Australia. Besides
350 gpm, GN has 200gpm, 500gpm, 800gpm, 1000gpm standard models.

Drilling fluids are used to aid the process of drilling
boreholes into the earth in geotechnical engineering, usually while drilling
oil and natural gas wells, drilling simpler boreholes such as water well, and
also doing some construction projects such as bored piling and tunneling.
Liquid drilling fluids is also known as drilling mud, and usually divided into
three main categories: water based mud( abbreviated as WBM), oil based
mud(shortened as OBM), and synthetic based mud(SBM). And also there has been a
new kind of drilling fluid which is called gaseous drilling fluid. The majority
of WBM is a mixer of water, clays(mostly commonly is bentonite) and other
chemicals which is homogeneous. To the contrary, the base of OBM is petroleum
product such as  diesel fuel.

 Drilling fluids can cool, lubricate and
clean the drilling bit. If not, the drilling bit will fail rapidly. Drilling
fluids can remove the cutting from well, and suspend and release the cuttings.
Drilling fluids can control the well formation pressure and maintain the
stability of well holes. Drilling fluids can seal the permeable formation and
minimizing the damage to formation.

 It is very expensive to composite drilling
fluids, so solids control systems are used to remove the solids contented
in the drilling fluids coming out from well and collect clean liquids for recycling usage. In
a complete set of solids control system, shale shaker is the first stage
machine to remove coarse solids from the drilling fluids which usually are over
100 microns; and then cyclones are the second and third treating machine to separate
solids over 25 microns out, and then decanter centrifuge is the final stage
machine for fine solids removal usually between 2 to 7 microns. When finishing
the solids removal process, the liquids will be clean enough to be reused. And
if needed, some chemical will be added.
