High Configuration 500GPM Mud Systems for HDD Rigs

Among all the fields that GN Solids Control
is professional in, HDD Rig’s mud recycling systems or
units are one of the most important and specialist one. Since its establishment
years ago, GN has been providing large HDD contractors in and out of China.
Now, like the largest HDD project contractor in China, CPP, is a long-term
client of GN Solids Control, at beginning of this year, CPP signed order to GN
Solids Control, with 8 sets of 500 GPM mud recycling system, with the highest
configuration.

Each year, GN will produce tens of such
systems, mostly for clients from market abroad, like Australia, Thailand,
Singapore, India, Kuwait, and some countries in Africa. GN has a series of
mature products of mud recycling systems for HDD, with most popular treating
capacity as 200 GPM, 350 GPM and 500 GPM. Of those, 500 GPM systems are most
frequently used in China.

For the same capacity systems, 500 GPM, GN
has different configurations for option, both economic configuration and
premium configuration available.

The most difference between the economic
configuration and premium configuration is the treating equipments. This time,
for the order of CPP, it is the premium configuration, with shale shaker, desander cones with under shaker, desilter cones with under
shaker and 2 sets of decanter centrifuges. For a normally economic
configuration, there is some times a mud cleaner which is combined by a mud shale shaker, a desander and a
desilter, and in most cases there is no centrifuge. And when more treating
equipments are used, there will be larger surface for them, accordingly, the
storage capacity is enlarged.

In case of Piling work or TBM projects, the
mud system, or so called slurry plant is simpler. Normally the slurry for such
projects is not requested to be treated so fine, so there is no need for
desilter cones, only to choose enough desander cones according to the desired
treating capacity. And for Piling mud systems, there is no mixing facilities.

Treatment of Drilling Waste

All wells will be drilled with the
generation of waste , the waste contains different type like drill cuttings ,
waste water , drilling fluids without used and completion fluids . The treatment on waste will be
depending on the drilling fluids type. There are different ways to treat
drilling waste like reduce , reuse , recycle and recover .

Recycle of drilling cuttings is
what GN Solids Control supply , there will be two sets screw conveyor to pick
up drilling cuttings from shale shakers and feed to vertical
cuttings dryer for treatment , then the vertical cuttings dryer will process
drilling cuttings with water or oil content below five percent , the dry
drilling cuttings will be deliveried away for further treatment and fluids
content will be delivery to a small holding tank , there will be a small pump
to pick up recycled drilling fluids and feed to a high speed decanter
centrifuge , the dry solids from centrifuge will be delivery away and clean
fluid can be drop to the clean tank in solids control system .

The vertical cuttings dryer was
used mainly for oil base mud drilling cuttings but the GN new improvement make
it working for water base mud drilling cuttings also . GN Solids ‘s vertical
cuttings dryer is 900 RPM with G force up to 420 G , the super high speed is available
at 1200 PRM with G force up to 750 G for a better separation ability . The
flights on the rotor is hard facing to HRC 65 , longer life than our comptitors
. The individual oil lubrication system with automatic alarm for pressure limit
. The main motor and oil pump motor is interlocked with each other for avoiding
the start of the main motor prior to the start of the oil pump motor .

Higher Environment Standard for Oil & Gas Waste Management

Although the price for crude oil is dropping form an extremely high place to anunexpected low place, the global demand for the oil never ceases. But as longas the drilling projects are done everywhere in the world, the environment
effects are shown more and more clearly.

Now more and more countries are issuing
laws and regulations for protecting the environment. Before, in some places,
after drilling, the drilling cuttings could be buried in a remote place, but
now, nothing is allowed to be discharged without further treating. In some countries,
any drilling work is allowed without seeing an existing waste management
solution or system.

Depending on different drilling fluids, the
waste management system is a bit different. Normally, there is WBM and OBM.

1. Complete WBM waste management system.

A complete WBM waste management system is
combined by 2 sections. First section, standard waste management system
includes a drying shaker with a high G force and a high speed decanter
centrifuge. Second section is further
treatment, a dewatering unit to flocculate the fine particles into larger ones
in order to be treated by a high speed decanter centrifuge, here, the
centrifuge may be same as the former one, but this one is regarded as
dewatering centrifuge. This whole system is called as zero discharge drilling
system.

2. Waste
management system for OBM

The complete waste management system for
OBM could also be regarded as 2 sections, the standard one and further one. The
standard waste management system for OBM is combined by a vertical cuttings
dryer and a high speed centrifuge. After first stage, the further stage is to
make the cuttings more compact and into solid before discharge.

GN Solids Control is most famous China
brand for solids control and waste management systems and equipments. They are
producing high speed centrifuges for waste management, and their products are
of high cost-effectiveness. And also, GN Solids Control is first Chinese
company who designed the vertical cuttings dryer years
ago. Now their vertical cuttings dryer reached the 4th generation, which could provide
more applications suitable for not only OBM and SBM, but also WBM.

If you need to know more about GN and GN
products, you are welcome to attend the coming CIPPE in Beijing, Capital of
China.

GN Decanter Centrifuge to Africa Customer

As an expert in solids control equipment andsystem, GN solids control manufactures and exports a complete set of
solids control equipment and system including shale shaker, desander, and
desilter and decanter centrifuge. At the beginning of this year, GN solids
control received a repeated order that a customer with which GN has cooperated
for more than three years, and this customer is satisfied with GN decanter
centrifuge, high quality with competitive price. And this time, GN has
updated its design for more stable and better performance with several update.

The updated decanter centrifuges still has
the below advantages of the last edition.

1. The
cylindrical and conical section of the bowl is made from duplex stainless steel
2205 which is better than stainless steel 316L. Stainless steel 316 is always
adopted by China’s other solids control company; even stainless steel 304 is
adopted.

2. The bowl is manufactured by centrifugal cast which means that the bowl has a
better balance. Only the decanter centrifuges pass the balance test, they can
be delivered.

3. Tungsten
carbide tile is attached on the screws to protect the screw from wear, and when
the tungsten carbide tiles is worn out, it is easy and convenient to replace
with re-doing the balance test.

For the updated decanter centrifuge, there
are more advantages:

1. Solids
discharge cover is added above the solids discharge port to prevent the solids
discharged to the inner cover of bowl.

2. Special
ceramic mud distribution port on the screw will extend the decanter centrifuge’s
service life.

GN solids have made it policy that GN
solids control will keep to update its product for better service and provide
better services. It is a wonderful start in 2015 with the big order from a customer,
the first batch has been delivered, and the second will be delivered soon.
