GN engineer just came back from a rig jobsite for the commissioning of GN drilling waste management dryer system for a Nigeria drilling company.

It is a reputable drilling company. All their rigs are big oil and gas drilling rig 1500hp. Mostly, they use OBM (oil based mud) or SOBM for drilling. WBM (water base mud) is not normally used. So waste management system is necessary for them. One the one hand, it is request by the company for environment protection. On the other hand, it can recovery drilling mud for reuse, and save their drilling cost on chemicals for drilling fluids.

Drilling waste equipment GN offered to the Nigeria drilling company

1) Drilling waste decanter centrifuge GNLW363C-VFD

GNLW363CG-VFD decanter centrifuge is the most popular model for drilling waste management field. It is the latest design from GN group. It is a 14 inch variable frequency drive decanter centrifuge with max. speed 3900rpm.

2) Vertical cutting dryer GNCD930

Vertical cuttings dryer is widely used together with drilling waste decanter centrifuge for OBM (oil base mud treatment). The VG dryer is made and designed by GN Solids Control. GN Solids Control is the No. 1 manufacturer for drilling waste vertical cuttings dryer exporting.

3) Screw pump cater for drilling waste transfer

Screw pump can transfer mud and feed for decanter centrifuge. The screw pump GN cooperate with a German company NETZSCH. All fluids touch material made from Stainless steel 316L. GN can offered good quality with good price.

4) Screw auger conveyer in difference sizes and transfer length for waste cuttings transfer.

GN standard screw conveyer is with 12 feet length for each section. Customer can choose 1 section ~ 4 section to get length 12 ft, 24 ft, 36 ft or 48 ft. Auger diameter have 12 in, 14 in and 18 in for option.

GN can offers customized solutions on drilling waste cuttings management system. Welcome you contact GN group freely for solution.

GN Solids Control is a big centrifuge supplier from China. GN Solids Control is a big solids control equipment supplier from China. GN Solids Control is a big drilling waste management equipment supplier from China. GN Solids Control is a big vertical cuttings dryer supplier from China.

After about 8 years’ experience in solids control & drilling waste management, GN Solids Control is No.1 Company in this field and we have cooperation with many international company on solids control service and drilling waste management service. Like, we have customer below:

1) Customer from Russia Baker Hughes, Baker Hughes is international oil Service Company which will join Halliburton to gain stronger relationship.

2) Customer from Egypt. However, they are Africa largest mud service company with operation base in Egypt, Algeria, Sudan, Libya, Saudi Arabia, Kuwait, Oman etc.

3) We also have strong partner from Iran, which is largest mud service & solids control service company in Iran. They have lots of business contract with NIDC which holding over 70 drilling rigs.

It is our honor to work with international oil service companies, like NIDC, CPVEN, ONGC, NNPC, CNPC, SINOPEC, CNOOC, SDPC, KOC, KDC, Aramco, EDC, ENTP, etc.

Why most of international buyer purchase solids control equipment from GN Solids Control?

Because GN Solids Control target on high quality products with reasonable price, we never do lower quality product with pretty lower price to disturb the market. Our equipment including below items:

1) Vertical cuttings dryer: This equipment is used for treating about the wet and coarse drilling solids discharged from solids control equipment. After treated by GN vertical cuttings dryer, the solids can be very dry for easier transportation and the separated oil can be reuse.

2) Decanter centrifuge: Decanter centrifuge can be used for solids control service or drilling waste management service, different project require different bowl size centrifuge with different bowl speed. GN Solids Control can offer different model centrifuge to fit customers’ requirements well.

Since last year, GN has sold to middle east market several sets of desander plants, for the HDD contractors. Besides Oil and Gas solids control and waste management equipments and systems, GN is also professional in mud recycling systems or called desander plants for HDD, CBM and Piling rigs.

In some jobsites in middle east countries, the drilling mud are conserved in a mud pit or buffer tank after drilling, and the mud recycling system or desander plant sometimes are located on a trailer and to be transported from one place to another to treat the mud.

There are always 2 steps of separation equipments in a standard mud recycling system for HDD drilling rigs, the shale shaker and the desander cones. In order to make the mud recycling system to be more compact, GN designed double deck shaker with desander cones. The drilling mud to be treated is firstly transported to the lower deck shaker, which has a bigger mesh holes than the upper one, it is the shale shaker phase. After that, the liquid phase of mud falls into the tank under the shaker and sucked by a centrifugal pump to the desander cones on top of the shaker. The liquid discharged from the desander are clean mud, while the solids part falls onto the shaker under the cones, this layer of shaker is located between the lower shaker and the desander cones, it is the drying shaker for desander cones. Above mentioned is the separation step. Then comes the mixing step. There is also a mud jet mixer in the system, to add necessary chemicals into the system.

A very famous middle east HDD contractor has purchased from GN Solids Control a set of 240 cubic meter HDD mud recycling system as a trial order, now they have tested it on their jobsite and it proved to have good performance. Now they are sending repeated order to GN

We need a solids removal unit, for our diamond drilling projects, it moves often, and as you know it is a small rig. Since GN has designed solids removal units which can be loaded by helicopter, we know exactly what this means to the diamond drilling projects. Far away from the downtown, and live with animals, can’t find live people living there.

For these two systems to South America, glad that they do not need load by helicopter. Then all we need to do is:

1) All equipment in this unit for solids removal

2) Keep it compact, flexible, easy for transportation.

Absorbing experience from the systems we designed before, and our more and more knowledge on diamond drilling projects. Here is the solution.

Equipment: Like most of the solids removal units for diamond drilling, it contains a small shale shaker, small decanter centrifuge, centrifugal pump for feeding centrifuge & mixing, generator.

Here come two main features of this system:

1) One pump for two purposes. The centrifuge capacity is very small, and has to arrange a bypass pipe to return the extra fluids. While we have a pump for mixing, then why not deduct one and make them together.

2) All in ONE. the generator also can be a built in product. As for most of the diamond drilling projects, the rig is hydraulic, and people like hydraulic, as it is simple for the hydraulic experts. While there is not so many hydraulic shaker motor suppliers, especially such small ones.

What you can get from this system:

- Save your cost: there are many ways saving cost, combine two pumps to be one, change screens properly, then when centrifuges shut down, the system still working

- Nonstop working: though we move often, we do not want breaks because of the centrifuges, shakers can be widely used.

- Self-contained generator saves a lot of trouble, pls do not ask me for power supply, and prepare it!
