After more and more accidents, also the sea environmental protection comes to PEOPLE's sense, now offshore projects taking care more about the drilling waste disposal. Maybe before it is just a screw conveyer, or a channel for washing to the ship's rail, then slicking to the sea.
So the bentonite, the polymer, cuttings, or whatever you may bring up from the mixture of drilling prodution, go to the sea.
For land rigs, now normally the drilling mud service company, or the contract might handle this with driling waste management system, like the one we just sent to West Africa. It contains Drilling waste management unit equipment list

• One Centrifuge high configuration centrifuge GNLW363BG-VFD.
• One set Cuttings Dryer GNCD930C, fixed speed (800rpm), high configuration dryer, equipped with air line, upgrade scraper and basket screen.
• One set Vertical slurry pump GN50YZ20A-18 for feeding Decanter Centrifuge
• One set Netzsch Brand NEMO pump for flushing cuttings dryer
• One set skid, flexible legs, accessories and electrical control panel system
  Offshore drilling waste normally also contains such equipment, giant contractors for offshore projects normally are solving these problems. While for the design of such systems, different engineers have different ideas. Just like solids control, we also have construction engineering difference. What GN Solids Control insist is simple is beautiful, make everything just simple. Less equipment, more work, which makes the system more powerful.
  There also many differences, between designing onshore projects, the limit space, the whole consturcture, the ambient, sometimes we even have to consider where is it located, as the PH different, then have to use high config stainless steel.
  GN Solids just went to SCIPPE in Shanghai, which is for oil & gas, showed the latest update decanter centrifuge, speed upto 3900rpm. Also more and more good news regarding cuttings dryer feedback to us.

What we have been doing is build user friendly mud system, which drillers will be happy to use, saving their backs and their bottom line; and contractor are satisfied, make more money, with saving cost! Use GN Portable Mud System to make the money that you deserve for all water well drilling projects.

Q1: How much training required, Do we need P.H.D?

This mud system does not require a P.H.D. in engineering, or get 30years experience to operate. Do not require an enormous amount of training and extensive technical education to operate.This baby is simple, affordable and dependable. It has the power to remove the solids and make your well drilling more productive. Saves you time money and stress, and maximizes safety and productivity.

Q2: How much invisible cost? How to keep it in budget!

After I have a budge, I purchase a mud system, then I need replace parts, especially screens! All GN shale shaker use pretensioned shaker screens, to extain the screen life, and enhance the performance.
Now also have composite material avaible, if you choose GNZS594 shaker, others still on the researching process.
OK, then pumps. YES, GNSB centrifugal pump is replacalbe with Mission! Sounds convenient, as easy to find Mission spare parts.
Normally other supplier like to sell spare parts in high price, and make a lot of unique ones, to make sure only they can supply. THIS IS NOT GN SOLIDS CONTROL.
All GN spare parts will be on reseaonable price. Can send proposal when you purchase the mud system.

Q3: How to MOVE easily?

Normally GN will check transportation limit, fold up the walkways, build in the stairs, and use container type mud tank. Then have trailers, jack up legs for your option.
Also we can combine the generator on a same package. From Cummins or CAT.
Eventhough, will you send some guy help us for commissioning?
YES, if required, our after sales team is always ready to be helpful, and show you how to operate the system.

GN500GPM TBM mud treatment system is designed and manufactured according to clients’ requirements. Its handling capacity is 500GPM. This system is composed of two classes solids control equipments. While at the same time, three times separation, the first phase is double deck shaker, first the dirty drilling mud comes to the coarse screens, then to the normal 40mesh screens.

• First class: 1 sets GNZS706E-HB linear motion shale shaker for sieving seperation;

• The second class : 1 set GNZJ703E-8N mud cleaner and 1 set GNSB6×5-12J sand pump. Its main principle is adopting sand pump to supply enough power for hydrocyclones, then ,drilling fluids can be under centrifugal separation through hydrocyclone cones;

• Meanwhile, install 1 set GNSLS35A jet mud mixer in the tank. By this mean, it can add and mix mud to supply satisfied drilling fluids for drilling rigs.

Main function & features

1. this system consist of 2 classes solids control processing.:a.shale shaker sieving separation ; b. desilter hydrocylone separation can discharge most particles size more than 20μm in drilling fluids.
2. Adapted shaker screen for GNZS706E-HB linear motionl shale shaker: First deck coarce screen: 750*900mm, 3mm seive wiring, Second deck: 1250×700mm ，40―100 mesh shaker screens. Adapted under fluids shaker screen for GNZJ703E-8N mud cleaner 1250×700 ，100～180 mesh stainless steel frame screen.

The GN500GPM mud treatment system is applied for recycling, cleaning the drilling fluids coming from the drilling rig.Through the user-own mud pump, mud can be sent to inlet manifolds of the system. this system can eliminate sands less than 20μm in size, and supply drilling rigs with satisfied drilling fluids.

As the purpose is different, though 500gpm for HDD or TBM have nearly same equipment, same structure, they get different design.
While we all know TBM have very big particles, then it must have a coarse seiveing screen separation, then we normally prepare a double deck shaker at the first stage. The system for HDD one deck is enough.
Regarding the working process of the recycling system, for the TBM: Firstly, start up the shaker box locking device of GNZS706E-HB linear motionl shale shaker & GNZJ703E-8N mud cleaner(as its operation please refer to the related user manual) in Recycling Tank, and have a trying operation. Then start up pumps.
Now we get the difference, different as the normal 3phase, or 2phase separation, we must have different compartment for sediment, then we can get better solution, lower density / viscocity, closer to the water result.
