Modular Drilling Cuttings Waste Management Equipment for China TOP Oil Company

Since recent
months, China as many other countries as established more strict laws for
forbidden the drilling cuttings from the Oil and Gas drilling projects to be
discharged directly to the outside or anywhere else. They call them zero
discharge solutions, such solutions should be used for treating the drilling
cuttings in order to protect the environment.

Just like this
jobsite of CNPC, it is located among the farmlands and not far away from the
town. But they have found a rich oil reserve in this long time existing
farmland. Energy resources have to be explored, meanwhile, the farmlands must
to be well protected. Therefore an effective way to treat the drilling cuttings
is an urgent and very necessary solution.

They, like many
other clients of GN Solids Control chose GN waste management
systems
as option and GN equipments are proved to have good
performance. Just in last year, GN Solids Control has sold around 20 sets of drilling
cuttings waste management systems to both domestic companies in China and also
abroad, clients including Baker Hudges, Shell and other world famous companies.
Most of them purchased standard GNDC series drilling cuttings waste management
systems including vertical cuttings dryer, high speed decanter centrifuge,
screw conveyors and screw pumps.

Some other
companies chose instead independent equipments per their special need and
applications, like GNLW363CG Decanter Centrifuge, they are using it as
centrifuge for treating the oily sludge on a telescopic skid, or for a
dewatering centrifuge used together with a dewatering unit, like for NIDC and KOC.

This year, for
providing most of clients’ special requests, GN Solids Control has designed
some modules for waste management. When they are used singly, they play roles
as dependent equipment for their original functions, and when they are used and
laid together, they could easily form a complete system. And during
transportation, they can easily to transport in containers.

Like in some
cases, normally you use vertical cuttings dryer and centrifuge is enough. But when
you need a high G shaker in between the above mentioned 2, you don’t have to
change to another system, just add some pipelines into it and locate a shaker
module at a suitable position.

6 Sets of GN Decanter Centrifuge and 40 Sets Mud Agitator Delivered to South America Market

GN leads the way in solids control
technology with it new designed decanter centrifuge in
China. As the firstly API certified manufacturer of solids control equipment and
system in China
, GN has always been keeping its leading position in
international market by it advanced technology. Early in this year, GN has
improved its decanter centrifuge to make it more suitable to treat drilling
waste which contains relatively larger solids content. So GN made a series
specific design to reduce abrasion on the screw conveyor and avoid solids accumulating
inner the bowl cover. The new designed decanter centrifuge has been proven to
have stable operation and more satisfying performance, thus becoming popular in
the international market, especially in the Middle East and Africa, Latin
America. Recently GN delivered 6 sets of decanter centrifuge and 40 sets
agitators to South America. The new designed centrifuge also can be used as the
final stage solids control equipment in a complete set of solids control system for
oil and gas drilling.
The mud agitator is used to rotate the mud to
keep it homogenous.

Now GN is manufacturing one set of solids
removal unit for a South America customer. It will be used the clean the
diamond drilling fluids for recycling usage. Besides solids control systems for
oil and gas drilling, GN also designs and supplies desander unit for bore piling and TBM; mud systems for HDD
drilling, CBM drilling, water well drilling, geothermal drilling. The main
treating equipment is shale shaker and desander, desilter, or mud cleaner with
the combination of desander cyclones and desilter cyclones. The shaker is used
to separate coarse solids, and then the desander to separate solids over 40 micrions,
and the desilter to remove solids over 25 microns.

Two Sets Close Loop Drilling Waste Management System for Domestic Oilfield Project

Because of the more strict environmental regulation
on drilling project that no cuttings without treatment are allowed to be
discharged into directly into the pit and buried, almost all drilling sites
equip themselves with drilling waste management system.
In 2015, GN solids control, the international brand of solids control and drilling
waste management, has delivered to over 30 sets drilling waste management
equipment to China’s drilling site. Recently, another two sets of drilling
waste management equipment starts to operate in China’s oilfield drilling site.
For the drilling waste management, high G shaker is generally used to treat water based mud
cuttings as the first stage, and then the liquids will be fed into the high
speed decanter centrifuge for second stage treatment; vertical cutting dryer is
generally used to treat oil based mud cuttings as the first stage, and also the
second stage treatment machine is decanter centrifuge.

Since GN firstly designed and manufactured
the vertical cutting dryer in 2011, GN has many successful case now. One of
them is the oilfield service Giant Baker Huges ,who took 4 sets complete
drilling waste management system from GN and applied it in Siberia with very
low temperature at minus 40.

 Recently, we have customer from CPP, China petroleum
pipeline bureau company, the largest HDD contractor from China. They just buy 2
sets of
500gpm mud system
, each system equipped with 1 sets shaker with 2 ea desander
cones, 1 set shaker with 12ea desilter cones, 2 sets middle speed centrifuge
GNLW452. The middle speed centrifuge standard model is fixed speed centrifuge
with 1800RPM. The customer like customized centrifuge with variable speed
control panel. We company customized the fixed speed centrifuge to variable
speed centrifuge by adding one variable speed control panel with ABB transducer
inside to make the speed changeable. 1 set of GNLW452 centrifuge with treating
capacity 40m3/h, two sets means treating capacity 80 m3/h at same time. In this
case, the barite material in drilling mud can be take out by centrifuge very
fast. Thus, the total working efficiency will be promoted in a high level.

 Except of GNLW452 middle speed centrifuge, GN
Solids Control also have other model centrifuge for other application.

 1) GNLW363CG or GNLW363CG-VFD is high speed centrifuge,
fixed speed / variable speed two options for customer. This centrifuge is
professional for drilling mud weight reduce for solids control. Or it can be
used for drilling
waste management
to remove the very fine solids from drilling waste, thus to
reduce the oil on cuttings (OOC).

 2) GNLW553 big bowl big capacity centrifuge. If in some
certain case, the customer don’t want to use desander unit or desilter unit,
the customer may only use shale shaker & centrifuge for fast drilling. This
kinds of combination can also reduce the power consumption in a large degree. Because
when you use desander units or desilter units, big pump with electric motor is
generally needed.

 GN other model centrifuge, like GNLW223 baby centrifuge,
GNLW453 big bowl centrifuge is also available.
