drilling waste management | GN Decanter Centrifuge

Higher Environment Standard for Oil & Gas Waste Management

Although the price for crude oil is dropping form an extremely high place to anunexpected low place, the global demand for the oil never ceases. But as longas the drilling projects are done everywhere in the world, the environment
effects are shown more and more clearly.

Now more and more countries are issuing
laws and regulations for protecting the environment. Before, in some places,
after drilling, the drilling cuttings could be buried in a remote place, but
now, nothing is allowed to be discharged without further treating. In some countries,
any drilling work is allowed without seeing an existing waste management
solution or system.

Depending on different drilling fluids, the
waste management system is a bit different. Normally, there is WBM and OBM.

1. Complete WBM waste management system.

A complete WBM waste management system is
combined by 2 sections. First section, standard waste management system
includes a drying shaker with a high G force and a high speed decanter
centrifuge. Second section is further
treatment, a dewatering unit to flocculate the fine particles into larger ones
in order to be treated by a high speed decanter centrifuge, here, the
centrifuge may be same as the former one, but this one is regarded as
dewatering centrifuge. This whole system is called as zero discharge drilling
system.

2. Waste
management system for OBM

The complete waste management system for
OBM could also be regarded as 2 sections, the standard one and further one. The
standard waste management system for OBM is combined by a vertical cuttings
dryer and a high speed centrifuge. After first stage, the further stage is to
make the cuttings more compact and into solid before discharge.

GN Solids Control is most famous China
brand for solids control and waste management systems and equipments. They are
producing high speed centrifuges for waste management, and their products are
of high cost-effectiveness. And also, GN Solids Control is first Chinese
company who designed the vertical cuttings dryer years
ago. Now their vertical cuttings dryer reached the 4th generation, which could provide
more applications suitable for not only OBM and SBM, but also WBM.

If you need to know more about GN and GN
products, you are welcome to attend the coming CIPPE in Beijing, Capital of
China.

GN has been ready for the slower grow of oil in 2015

Based on the latest news through the agency of international energy, producing oil has a tiny bit growth in comparison with the former estimate, since the economy of the world is still suffering a really weak growth.

Also it appears the OPEC (Organization of Oil Conveying Nations)unwilling to give belief about the growing yield of oil in the next year .there has been not any signs of this situation so far.

International Energy Agency has create a second estimate and cut lower the development of oil demand by 3 hundred thousand barrels every single day, in comparison with the former estimate this can be a sharp decrease. They feel the following year’s demand growth come in the range of 1 million to 94 million. Besides, they believe within this year the development of oil demand is roughly from two-hundred thousand barrels each day to zero point seven barrels each day.

However, you will find several regions or nations includes a slightly oil production growth. The oil producer of OPEC, for example Saudi Arabia has created a lot more barrels oil, from fifty thousand barrels every single day to roughly tens of millions of barrels each day in September. Many people think that the oil production growth will has some great quantity which can make a large jump (one-hundred and thirty thousand) in the next year.

For all of us, some surveys recommended the oil production could keep growing and exceed Saudi Arabian oil supplies and Russian oil supplies.

GN is really a well-known brand focusing on solids control and drilling waste management areas for a long time. Thinking about the bad year of 2015, GN has prepared it with revolutionary, from top management to on-site workers, everybody expect a sizable change and it is sure that every employees will try his best to make contribution for GN Solids Control Company.

Soil and Liquid mixing tank

GN Solids Control is China leading manufacturer on mud solids control and drilling waste management system. They have experience on oily sludge separation. Recently, there are customers request V-bottom mud mixing tank for soil and oil liquid. The soil and oil liquid will go into the tank and they are mixed

The output line from the tank is a screw type (screw conveyor), so it can deliver the settled solid particles. And the height of the end of screw is 3 meter. Finally, there should be a liquid pump to transfer the liquid to other tanks or equipment.

V-bottom Screw + Shiftless conveyor

1) Solid/liquid mixture will be go into the v-bottom screw.

2) V-bottom screw and shiftless conveyor are put together and have sealing for no liquid leakage

3) Solid will be taken out from bottom screw – shiftless conveyor – and be discharged

4) Liquid will be pumping out from the top or making a hole at proper elevation

GN Solids control can provide tank and augers to meet the required function.

Below is a draft proposal made for customer’s reference.

1) Height of tank (including V-bottom) : 1.8 meter

2) Width of tank: 2 meter

3) Length of horizontal auger in tank : 24 feet long ( 7.315 meter)

4) Length of tilt auger: 24 feet long (7.315 meter), with tilting angle between auger and horizontal level 25 degrees.

Customer is satisfied with the proposal and mentioned more request. They want steam heating system for the mixing tank:

– Steam injection nozzles (in this case, 2 nozzles each side (total 4 nozzles) can be installed and the nozzle would be positioned 0.5m from bottom)

– Wired screen (5 cm) on the top where operator pour the soil into the tank.

Per customer request, GN Solids Modification V-bottom Screw conveyor:

1. Steam injection line and nozzles inside

– steam injection line is split to two lines which are inserted into the v-bottom screw tank.

– 3 injection nozzles from each pipeline inside of v-bottom tank

– steam injection pipeline: 2 inch diameter (see picture below)

– no need of mixer inside

GN Mini Centrifuge

You might become complacent that the machine is big monster having a large footprint and high weight. It always gets people to feel gloomy when standing before an enormous machine. But consider the following picture, how cute it’s. It’s a small decanter centrifuge from GN decanter centrifuge products. With small footprint, you can easily remove and transport, additionally, it saves a great deal space for customers. Regarding its parameter, the mainly two is dealing with capacity and speed. GN small decanter centrifuge’s dealing with capacity or processing volume is 6 cubic meter each hour. And it is speed can achieve to some maximum round each minute.
