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.

It will be a long road if the client is critical, and if politicians swings, things change again. For turbulent Africa, for this project, the fruits comes after 5 years flower blooming. The client comes to check all the details, to make sure that everything is right, real trial test, operation, and leaving with thumbs up, simling face.
As keep following on all our products design, and all projects of drilling waste management for other clients, the client tried to absorb all the advantages from other projects. Here comes the final one.
Main equipment c/w two containers, flexible, compact, and easy for sea shipping. As you may find in the brochure of drilling waste management system, normally three modular package included.

1. Waste Mechanical Separation
In this system, in one container, contains verticle cuttings dryer, High G dryer shaker, and decanter centrifuge.
GN dryers is with higher speed up to 1200RPM with G force up to 750G. This gives it more ability to separate the oil on the cuttings, especially of WBM, it works well for the critical WBM. GN 363 series Decanter Centrifuges is the most popular size decanter centrifuge for drilling mud treatment. GN built over 100 this size of decanter centrifuges in 2014. This type and size of decanter centrifuge is popular for solids control, dewatering ,waste management, sludge treatment.

2. Then here comes another 20ft container, which loads the flocculant & coagulant mixing unit inside, add chemicals to make sure that all ultra fine particles can be separated.

Keep tune on this, will update more after after sales commissioning.
OK, if you want to have a look, kindly let us know your location, then we will see if can find some opeartion site nearby. Or pls check the videos from our website.

Like all news comes after exhibition, like this one 2015 OTC,GN Successfully Displayed Drilling Waste Management Equipment; there will be more good news coming, this is the one after the CIPPE 2015, which is two monthes ago: a Sichuan oil service company purchased the drilling waste management system displayed in CIPPE 2015.
Which containes the GNCD930C Series Vertical Cuttings Dryer, rotation speed upto 900rpm, G force upto 470. While ad-time GNCD930D series is also available now. GN has already done successful drilling cuttings management projects for Shell, Baker Huges, CNPC and many more leaders in the industry. Also contains a High Speed GNLW363CG-VFD Decanter Centrifuges.

GN 363 series Decanter Centrifuges is the most popular size decanter centrifuge for drilling mud treatment. GN built over 100 this size of decanter centrifuges in 2014. This type and size of decanter centrifuge is popular for solids control, dewatering ,waste management, sludge treatment.

As a system, all needed pumps, conveyors, pipelines, intermidiate tanks are included.
In this system, also contains a crane hoist, which solve the high renting charge of crane on the rig site. At least keep the cranes not traped here for the system feeding.
As we always keep telling, the statege, finally works well. When the flowers blooms outside the wall, people inside smells. Well, after big players comes to us, and like a healthy cycle, business is on the right track.
If you keep tune on us, there is more good news, to give the client an one stop solution for the drilling waste, to protect the environment; now GN have become agent of a TDU supplier in US, and we are now in training process to supply after sales service locally.
