drilling waste management | GN Decanter Centrifuge

GN Solids Control Engineers Commissioning in Africa

Although the oil and gas industry makes many oil
and gas pertaining companies to feel sad in the past year by the low price from
the crude oil, there are still likelihood for the good companies. Including GN
Solids Control, their own clients are still buying. The particular drilling
companies in South africa are still looking forward to a better future to come
by fully organized for equipments and staff members.
This time, GN Solids Control sent engineers to a Upper Africa company on
request with the client to do the having of 1 set of mud flower and 4 sets
connected with waste management systems.

That is a large drilling company with Africa which provides solids control and waste
management equipment and services to the essential oil companies who have
oil job areas in Africa. They use workers from local South africa while
importing equipments via all over the world. Before, they acquired equipment
from USA simply, but in case of the lower oil price, in order to get some sort
of squeezed benefit to be much larger, they choose to find vendors from China,
and they visited just about all main Chinese rig suppliers and solids control makers and finally
decide to buy from GN Solids Control.
Because:
one GN is most well known solids control manufacturer in China and taiwan and
also 1st API licensed in China.
2 . aside from API certifications, GN also obtained ISO, DNV CE, HSE and etc
certificates, exhibiting the responsibility of the company for the society and
environment.
a few. GN’s product including vertical cuttings dryer , shale shaker , shear pump , oilfield shale shaker , mud
cleaner , desander and
desilter , vacuum degasser , Mud Gas Separator
, decanter centrifuge , mud tank , mud agitator , etc .is the same as the US
and Europe providers, in another word, from GN, they can buy at a considerably
better price than US or maybe European suppliers but the high quality is
equivalent.
4. Reassured after sale service as well as spare parts, for main tools and
systems, GN give engineers for first time having and training for end user’s
operators for free for a single week.
Regarding spare parts, GN usually have necessary spare parts in commodity for
quick delivery.
That is why more and more drilling corporations and oil service global
businesses are choosing to cooperate along with GN Solids Control.

Dredging Slurry Separation System

It is very strange that China even
have more strict environmental requirement on the dredging field than all over
the world, on the waste solids disposal and also the fluid dump, no matter
how it have been applied on field, in paper it is really advanced. So
basically when the oil market is down, we get a chance there, some client
in dredging field said. Just like you have done in drilling
waste management field. Also we have realised that not
only china all over the world, people are taking more care on the
environmental protection. For dredging, what we need is: Recycle the cleaner fluids.

Dump and reuse as much as possible on
the solids.

Not like the oil gas drilling, from the
pond, or from the river, from sea, there are sands, rocks, and other
things as you can imagine which have been buried in it. So
the separation seems very different. Except the basic concepts.

Separate the biggest particles and
other stuff other than the sands and silts. There are many ways to do this, one
is dig another pit / pond, with at big screen from where dredging pump
feeds, let the screen separate unreasonable parts to the pond, keep them away
from the progress. Another way is gumbo box, it is quite same as
the mining applications, to separate the biggest rocks from the first
step, then others feeding directly to the shale
shaker.

Then directly, or by another pump from the
pond. The feeding goes to the double deck shaker. In GN Solids Control , it is GNZS706E,
which is good to separate the bigger sands and the most of
the bigger solids. going through two sieves.

Catched by the pump, feeding to the
cyclones, to get the silts separated.

Then in the same way, separated by the
decanter centrifuge.

Sometimes it also need help from chemicals
that why a flocculent unit is there. To concentric the small particles
to be bigger ones, then easier to be separated.

Kindly contact GN for a full solution.

GN Total Solution for drilling waste management

GN Solids Control is the first Tiongkok
drilling waste management gear company who can offer full solution for drilling
waste management Service Company.

Regarding Oil-based mud drilling cuttings, the entire solution of drilling
waste management including below methods:
Step 1: Vertical
cuttings dryer. Use this VG dryer to take care of the drilling cuttings,
get the valuable oil based soil. The OOC after cure can be 3%-5%.
Step 2: Energy Desorption Unit. After VG dryer, the solids can TDU for
nonhazardous ultimate treatment. After TDU, this inflatable water, oil and
solids may be separated in accepted level which comply with most of country’s
government policy on enviromentally friendly protection
Step 3: Decanter
Centrifuge. After VG dryer, typically the liquid part (drilling fluids) can
go to centrifuge to remove often the fine solids and get back to active mud
tank regarding reuse. Some client allow liquid part discharged via VG dryer go
back to lively mud tank
system immediately. This is also OK.

Regarding normal water based mud drilling clippings, the total solution of drilling
waste management including down below steps:
Step 1: High Grams drying shaker ( HG dryer). Use this HG dryer to treat the
drilling waste, recover the valuable drinking water based mud for using again.
The mud on waste after treatment can be all-around 10%.
Step 2: Solidification product. After HG dryer, the actual solids part can be
put straight into solidification unit to blending with cement or chemical
substances to get nonhazardous treatment.
Step: Decanter Centrifuge. After HG dryer, the liquid aspect (drilling fluids)
can go to centrifuge to remove the fine solid waste and go back to active
magnetic tank for reuse. A few client let the liquid portion discharged from HG
dryer go back to active mud container system directly. This is also ALL RIGHT.
GN Solids Control will be the
first solids control devices supplier with China basic & USA base and
Russia base from China. All of our equipment is working in over 70 countries
and areas, increasing good reputation from many purchasers.

GN Fixation Unit for Drilling Waste Management

GN Solids Control is complete line drilling waste
management solution provider, related equipment like vertical cuttings
dryer, High G dryer, cuttings fixation unit, thermal desorption unit etc.
Different countries have different regulations on the treatment of drilling
waste discharged from shale shaker & mud cleaner &
centrifuge.

Like client in Nigeria, most of land rig
oil drilling company do like this:

1)
Use one set vertical
cuttings dryer + one set decanter centrifuge at rigsite. During drilling
period, the drilling waste discharged from shaker will go to vertical cuttings
dryer for recycle and reuse. The discharge solids from vertical dryer will be
collected by cuttings skips. The drilling fluids will go to centrifuge to
remove fine solids and then, go back to active mud tank for reuse.

2)
The cuttings skips for vertical
dryer, cuttings skips for mud cleaner and cuttings skips for centrifuge will be
taken to mud factory which have thermal desorption unit for final treatment.

3)
Vertical cuttings dryer is
mostly used in oil based mud drilling waste management. If for water based mud
drilling cuttings treatment, high G shaker is mostly
used. Because of lower environmental containment of WBM, high G dryer is very
lower cost than vertical cuttings dryer.

Like client from Algeria / Gabon, they like
to use cuttings fixation unit for final treatment at rigsite. They transfer the
drilling waste into the fixation unit, with curing agent.

Except for the drilling waste management
equipment, GN Solids Control also produces large quantity of solids control
equipment. Each year, we provide over 250 sets shale shaker & mud cleaner
& desander &
desilter; over 150 sets decanter centrifuge; over 400 sets centrifugal pump
& shear pump & submersible slurry pump & screw pump.

We can also offer complete line of solids
control mud system for oil & gas drilling big drilling rigs; compact small
mud system for HDD small rigs/ water water small rigs etc. For clients with
similar requirement, pls contact us freely.

Chemical substance enhancing centrifuge system intended for oily sludge

Compared with drilling cuttings (discharged
from shale shaker), oil sludge much more difficult to be treated along with
recycled. To have better perception of oily sludge, we have to understand what
oily sludge is as well as where it is from. Could you get more info from a
search engine engine. And from under chapter, we can know how to cure the oily
sludge and results we can get after therapy.
GN Solids Control is definitely
China & USA primarily based leading manufacturer for soids control &
drilling waste materials management equipment. Studied in addition to China
Oilfield Service Minimal (short for COSL), GN Solids Control develop the very
first sets of Chemical boosting centrifuge system for slimy sludge treatment in
commencing of 2015, after work site test and application, the result is great. COSL repeat another 3 sets centrifuge system
obtain in past several months.

1) Chemical enhancing centrifuge technique configuration:
a. one pieces small mud
tank to help suspending the oily sludge before treatment. Mud Brawler
installed to get better performance
udemærket. Chemical enhancing system. The consumer can add chemicals from
benefit hopper. All the motor with Chemical enhancing system is managed by a
separate panel attached with the system
c. one value packs GNLW363CG-VFD
decanter centrifuge. This centrifuge speed can be easily tweaked by the
separate VFD cp and get stepless speed adjusting. The centrifuge can get to to
3200RPM, remove extra fine solids 2-5 microns. There is a catching tank under
the centrifuge to hold the fluids parts discharged from decanter centrifuge.
All the parts is created on a 11 meter more time oilfield skid, with moving
points for easier motion.
d. Screw conveyors is likewise necessary for the system, to shifting solids
discharge / with regard to other application.
GN solids Control offer 3 value packs 1000hp mud drilling process and 1 set
17-tanks liquid mud plant to be able to COSL in last
year. We all build strong relationship along with COSL and are registered
devices supplier for COSL, Cina largest offshore drilling builder.
