GN Supplied 2 Units of Drilling Cuttings Management Systems for Chinese Client

Recently GN Company finished production of 2 units of Drilling Cuttings Management Systems for Xinjiang, China client, and would arrange shipment to client’s work site soon.

The Drilling Cuttings Management System is used for recovering drilling fluids from drilling cuttings as much as possible for reuse, which can save cost and protect environment.

There are two kinds of Drilling Cuttings, Oil based drilling cuttings and Water based drilling cuttings.

For oil based drilling cuttings, GN Company’s System can reduce the oil on the cuttings to 3%-5%.
For water based drilling cuttings, GN Company’s System can reduce moisture content for easy transportation.

This Xinjiang client ordered Oil Based Drilling Cuttings Treatment System. Oil Based Drilling Cuttings Treatment System includes two parts, cuttings drying module and fine solids removing module.

Cuttings Drying Module, its key equipment is Vertical Cuttings Dryer. Its working procedure is feeding Drilling Cuttings into Vertical Cuttings Dryer, then separating oil from cuttings, and passing through the screen opening to the collection groove inside the dryer unit, it is achieved by centrifugal force.
Opening size of the dryer screen is designed of 250, 350 and 500 microns as options for different size cuttings drying. And vertical cuttings dryer is equipped with flushing system and air knife system for cleaning of the mud collection groove and screen, in order to avoid block.

Fine Solids Removing Module, its key equipment is decanter centrifuge. The liquid effluence discharged from the cutting dryer would be pumped into decanter centrifuge for polishing treatment to remove the fine solids in drilling fluids. GN Company can manufacture decanter centrifuge from 9 inch (220mm) ~ 30 inch (760mm), with bowl length and diameter ration up to 4.2, and adjustable G force up to 3000G, for reaching client’s requirement in different projects.

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.
