As we all knew that The Chinese segment held the largest share of 41% of the Asia-Pacific drilling waste management market in 2013. This seems like one step to save APEC blue in the Capital Peking. GN Solids Control, as the first one supplying whole waste cuttings solution, and the first Chinese company operates their waste cuttings management equipment oversea, have been accepted by more and more local clients.

IT WAS NOT IN THE PLAN. We still hearing the comlains, when the client develop the new project, or process the project as planned, or even keep the old project ongoing, the environment protection rules are more strict. Then urgently we need the waste cuttings management equipment! To serve better on this specific circumentance, GN is now Keeping Drilling Waste Management Equipment in stock for quicker response. 

As all the guys know Chinese market, well known that now lots of companies jumped in this market, with or without, relative, irrelative experience; while with lower price.
Then why the big players choose GN Solids Control.
Baker Hughes; Shell; COSL, SINOPEC, ok, more than that.
The motive of all this comes from the GN team keep learning, keep improving. Have been the first one who did this well in China. For the verticle cuttings dryer, have been tested in Shell project, OOC below 3%. In Russia, cold winter, still get positive feedback from site.

BIGER THAN BIGGER
As a private startup, keep focusing on top quality products, and get more and more popular in oversea market, then reflects on the local market, to be a well-known brand.
Not like other competitors in China, GN is not stepping at the same place, keep learning, improving, then focus on the OBM / WBM waste cuttings management system. Then as a one stop, zero discharge solution supplier; solids control, waste cuttings management. To recycle, reuse all the useful resources to keep the drilling production environment friendly.

Zero discharge have almost become a modular requirement now in China drilling market, to comply with the demand of environmental protection, and as a young market for the drilling waste management, many many companies involve in this. Which makes things more comlicated, as all of the suppliers are trying to customized a solution for the clients. If the end user, or the buyer is not professional enough, all will be puzzled, and learn from their own mistakes.
As an experienced one stop solution supplier, GN have learnd from the experience of supplying modularized HDD mud systems. Now all drilling waste management system are modularized. For the whole process, can be separated to be a few steps.

1. Solids Control
This is where the drilling cuttings waste comes, and solids control system, drilling fluids recycling, is a standard one in driling site. Though a lot of different design.
2. Primary Treatment by Cuttings Dryer or High G shaker
2.1 Delivery Unit
To collect all the solids waste from the solids control system, the vaccum unit, screw conveyors, hose pumps are used as per different concept.
GN have designed a basic / modular delivery unit, c/w collecting hopper, hose pumps, skid.
2.2 High G shaker
High G shaker is widely used for the water based cuttings waste, as it is more effective to handle. Though cuttings dryer can do this well, it is too expensive to operate.
Also each High G shaker can be used as a separate modular unit, with hopper underneath.
2.3 Verticl Cuttings Dryer
Widely used & accepted by users for oil based waste cuttings.
3. Solidification Unit
Then the solids goes to the solidification unit
In China, GN as a pioneer to supply this unit in compact design, and cooperated with US suppliers, absorbing tech. from experienced companies, to serve Chinese market.
4. Dewatering Unit
As we all know after high G shaker, or verticle cuttings dryer, the liquid will be sent to the decanter centrifuge, while if it is not qualified, also need to be flocculated, treated by chemicals.

To know the detail design, pls ask for info. from GN Sales team.

It is a long way for GN to finally have some standard HDD mud systems to meet various needs from clients. It was a good way for clients to find a company who can do the customized mud systems, as after experiencing different mud systems from different suppliers; also for a new startup company, it is important to learn from the experiance on site.
After years of customization, now GN also designed several modularized / standardized mud systems for the HDD & CBM projects.

The standardized 500gpm GN500GL is one of them. It is a long history, and lots of GN customers are using it. Equiped on top of a 40ft mud tank, W, L same diemension as container, container lifting corner makes it more flexbile for transportation on site.
The system contains: GNZS703E, the updated shale shaker, GNZJ703E-8N desilter cleaner, c/w feeding pump, then enough space for jet mud mixer with jet mud mixer.

Except the tank, the shaker & desilter design also considering the flexible transportation. As we move it very often, client talk about this very often, especially normally dealing with this with oil gas solids control suppleir, lots of them do not have experience with small systems, also do not learn from international competitors, and hard to proceed the change inside the company; while GN solids control keep improving for the basic requriements. The desilte cleaner also have a specific design for this kind of system, to make it as low as possible, then most of the countries, with lower trailer, no need to disassemble anything, we can transport it.
As we all know the desilter is combined by under flow shaker, and desilter cones in frame; if we need to disassemble the frame, then the problem comes, how to disassemble and re-assemble a modular design and no screw type well solve this.

Chinese government have enact laws to protect the environment, especially the oil drilling projects, so now all are in need of drilling waste mangement equipments, as an industry leader, again chosen by another big player, Sinopec. While if only consider a young private company, no one have expected this before, just like the big brothers heard a good solids control supplier from oversea clients, then they realized that we have such a good supplier in China, what the hell we are keeping looking for good ones from oversea.

As in China, water based mud are widely used, the waste cuttings mostly are water based mud waste. As better application, High G shaker are most suitable solution, considering economical, automatical and so on. Though the new verticle cuttings dryer from GN can handle, cost more money.
Then the normall process comes this way, the screw conveyor collect all the waste cuttings from the shale shaker, to the GN cuttings delivery unit, which contains 2 hose pump and a big hopper.
By the hose pump, the cuttings are pumped to the High G shale shaker.
Some sites also goes easier way, put some slop plate, guide all the cuttings to the High G shaker. If it works, then it does not matter.

The High G shaker separate the most of the cuttings away. The cleaned mud go to next step, premium decanter centrifuge.

The premium decanter centrifuge is a higher standard one in GN, lots of design to improve the flow, result, and life time. If want to know more, pls check the link. http://gnsolidscontrol.com/drilling-cuttings-management/

Anyway, when the screw pump catched the fluids from shaker, then pumped to the decanter centrifuge, with High Speed (VFD), the particles bigger than 5microns are separated. The almost clean fluid can be recycled.

This time the project for Sinopec is 8sets, each sets got 2 High G shaker, 1 premium decanter centrifuge; and normally it works for most of the drilling projects, waste management. Combine this with the solids control ssytem, to be a NO MUD PIT / ZERO DISCHARGE cuttings treatement system.
