World leading manufacturer GN Solids Control offers complete drilling waste management system of water base mud and water base drilling cuttings, as well as oil base mud and oil base cuttings. Water base mud is the most normal type drilling mud for oil and gas drilling, especially in China. Here we have a brief introduction of the treatment system for water base mud and water base cuttings.

GN Solids Control system can recovery drilling mud as more as better, and reduce amount of solids waste as less as better. After the GN system treatment, the fluids can clean enough for reuse for discharge. The solids phase is harmless and dry; it can be used to make bricks or other applications.

GN no pit drilling waste management system for water base mud and water base cuttings are welcomed in China and outside of China. Like CNPC, CNOOC and SINOPEC are all equipped with GN brand drilling waste management.

The equipment for water base mud and water base cuttings are as following:

1) High G drying shaker. It is also called High G dryer, or drilling cuttings dryer. The Qty is 2 ea for 1 system. Model GNZS594HGE-LD. The shaker model is the 5 generation high G dryer shaker from GN Solids Control. GN own over 10 ea patent design for its main line equipment.

2) High speed decanter centrifuge GNLW363C-VFD. It is the most advanced design centrifuge for waste management from China. It replaced many U.S brand at different jobsite with its mature design and reliable performance.

3) Chemical dosing system and dewatering centrifuge: If the clean fluids from the high speed centrifuge will not be reused for drilling, it will be transferred to chemical dosing system (or called dewatering unit) for further treatment. After this step the fluids is clean and can be discharged.

4) Drill cuttings solidification unit. It is used to treat all the solids phase discharged from high G dryer shaker, from high speed decanter centrifuge and from the dewatering centrifuge. After the treatment of solidification unit, the solids can be used to make bricks for road construction.

Shale shaker is the main wearing parts of solids control shale shaker and drilling waste management high G dryer (high G drying shaker). And it is the most costive part of drilling activities. For example, 1 ea 1000hp rig, normally it is equipped 2 shale shaker and 1 mud cleaner, means 3 shakers totally. It is 3-panel shale shaker. And 1 shaker uses 2 batches screen every month. The rig will run out 216 pcs screens every year. If the screen lifetime short, the consumable screen quantity will more than double.

GN Solids Control is the top screen manufacturing from China, and services in USA. GN Solids Control is also China leading manufacturer on solids control shale shaker and drilling waste management high G dryer (high G drying shaker). The good experience makes GN more professional on screen manufacturing than other suppliers.

GN main clients are mostly shaker users, like drilling companies, mud services company or equipment rental company. Or big trading companies. In order to reduce their cost and give them better supporting under the low crude oil situation. GN Solids Control keep upgrade its process technology to improve quality and reduce the manufacturing cost, In this case, GN can offer lower price with higher quality replacement shale shaker screen for all GN clients. To thanks GN clients for their years’ supporting on GN, GN high quality replacement shale shaker screen is for sale now in the year start woth huge discount.

Besides the replacement screen for GN own design shale shaker, GNZS703 series, GNZS594 series, GNZS752 series. GN offer offers replacement for other famous brand shale shaker models. Below are part of the replacement shaker screens made by GN.

1) Replacement shale shaker screen for Derrick 500 shaker.

2) Replacement shale shaker screen for Derrick 2000 shaker

3) Replacement shale shaker screen for Swaco Mongoose shaker

4) Replacement shale shaker screen for Brandt King Cobra shaker

GN is a leading manufacturer of mud solids control system and drilling waste management system. And GN is a manufacturing with a longer history for drilling solids control equipment research from China and services in USA. With the new environment protection rules comes out in more and more countries, GN drilling waste management equipment becomes more and more worldwide famous, and exported to more and more countries.

GN Thermal desorption unit and GN Drill cuttings drying system is the most popular equipment used for waste management. But many clients are wondering about their performance, they do not know how to choose the suitable type for their projects. Below is a simple introduction to tell the difference of the 2 systems.

Brief Introduction of GN Thermal desorption unit (TDU)

It is also called TDU. It utilizes thermal desorption to treat the oily conents. Normally, the materials treated by TDU, the solids control should be no less than 40%. Other wide, it cannot be spilled well in the pyrolysis furnace.

What kind of waste sludge can be treated by GN Thermal desorption unit (TDU)

In theory, all oil type solids whose vaporization point is below 420 degree centigrade could be treated with this system. The oil type solids above mentioned is oil waste and a certain amount solids, like mixture of mud and sand. The pyrolysis furnace roller in this design heat the material in spilling way, and the material is pushed forward by shoveling plates welled with a certain angle on the roller’s inner wall. If the material is only oily mud, the spilling character would be lower.

Brief Introduction of GN Drill cuttings drying system

It utilizes different separation equipment unit to remove the solids from the fluids step by step. If The fluids can be reused for drilling.

What kind of waste can be treated by GN Drill cuttings drying system

It can be used to treat the cuttings discharged from shale shaker, desander and desilter. It cannot used to remove solids control decanter centrifuge.

Difference of Thermal desorption unit VS Drill cuttings drying system

TDU can get clean water, clean oil and very dry solids with OOC≤0.05%. But the capacity is very small, 1~2 tons per hour.

Drill cuttings drying system use vertical cuttings dryer, and high speed decanter centrifuge to treat the waste material. It can reduce OOC to 3~5%. The fluids phase can be reused for drilling. It cannot get clean end products.

The routing and correct running schedule is necessary for a reliable performance of oilfield decanter centrifuge, and it can extend the lifetime of the centrifuge.

When the oilfield decanter centrifuge arrived jobsite, check every part to ensure them in good condition. Then assembly it well.

The schedule to use GN made oilfield decanter centrifuge are as following.

1) When the centrifuge arrived jobsite, firstly, remove the supporting ring under the bowl, and then remove the fasten belt. The ring and the belt is used to protect the centrifuge bearing during shipment. They are used to protect the bowl from vibrate and rotating during shipment.

Note: You should keep the supporting ring and the fasten belt well for reuse. Every time when the oilfield centrifuge moved from one side to another side. it should be protected by the ring and the belt, and locked well.

Start the centrifuge in a short time to check the rotating direction. if the rotating direction is not correct, you should stop the centrifuge soon, check and Change the phase conductors of the motors.

1). Start and run oilfield decanter centrifuge back motor in a short time to observe whether the gearbox rotates in a correct direction, and make sure there is no adnormal condition occured. Seen from the small end of the bowl, the gearbox shall rotate in counterclockwise.

2). Start and run oilfield decanter centrifuge main motor to observe whether the pulley runs in the correct direction, and make sure there is no adnormal condition occured. Seen from the small end of the bowl, the pulley shall rotate in counterclockwise.

3) If all rotating direction is correct, and the centrifuge running stably, then you can start the centrifuge feeding pump, and feed the centrifuge from small capacity. When the centrifuge is running stably, you can increase the feeding step by step.

Here is only some main point for oilfield decanter centrifuge operation. For detailed operation schedule, please refer the manufacturer’s operation manual.
