As they know GN Solids Control is a specialist for mud solids control and drilling waste management. And GN Solids Control keeps growing fast. GN promotes new equipment and technologies every year. Their challenge is the short time to present to their client a new idea to improve solids control in their rigs. They need to submit their solutions within 3 days. GN Solids Control has rich experience for the zero-discharge mud recovery system, and offers them suitable solution very soon. Their client is looking for a new technology to increase the performance of standard solid control equipment system, improve quality treatment and consequently improve drilling operations with good environmental impact. Their idea which needs more technical support has as principal innovation from the standard process used currently to provide a separate kit including the following high performance equipment’s: 1) Two Decanter centrifuges with barite recovery 2) Combined mud cleaner with desander (means desilter + desander and shakers with one or double level). As their existing solids control system mud cleaner is very poor quality. They need to replace it. 3) Vertical cuttings dryer. 4) Small tanks to collect the fluids and transfer it to rig mud system As their clients may use oil based mud or water based mud. The cuttings type is not for sure. GN Solids Control recommend them to submitted the new idea to their client with two proposed design for OBM and WBM based on two skid: Modular 1: 1 full set of Compacted mud cleaner (desander + desilter) 2 ea feeding pump for the Compacted mud cleaner (desander + desilter) 1 full set of mud tank to collect the fluids recovered from mud cleaner, and transfer it to rig mud system. The tank system is complete with all pipelines and accessories (valves, ladders, guardrails, clean gate, walkways, etc…) within the tank system, explosion proof lighting system, and explosion proof control system for all the equipment within the tank system Modular 2: 1-skid cuttings drying system. Client can choose to use high G shaker for water base mud or VG dryer for OBM. Screw conveyors for solids transfer also showed for their information.

Vertical cuttings dryer is typical processing equipment for drilling cuttings treatment, especially for oil based mud cuttings. It can reduce the oil content in the cuttings to 3 ~5%. In many counties, it is meet the standard for discharge. And the 3 ~ 5% oil on cuttings is easy for transport, and it is easy for next treatment, like thermal desorption unit.

Per different jobsite layout, and the diferent jobsite requirement, there are many ways to feeding the drill cuttings to the solidification unit.

Option 1: Screw conveyor

Auger screw conveyor is the most popular way to transfer drill cuttings to the vertical cuttings dryer, especially for onsite treatment system. Firstly, there will be screw conveyors to collection drill cuttings from solids control shale shaker, desander, desilter and mud cleaner. And then the second screw conveyor system will transfer cuttings to vertical cuttings dryer. After separation, the clean fluids recovered from solids control treatment equipment (decanter centrifuge excepted) will be feed to high speed decanter centrifuge to reduce the mud then, and then the recovered mud will be qualified for reuse again.
But if the drill cuttings is in the waste pit, or the liquid content is very high. Screw conveyor is not suitable.

Option 2: Vacuum transfer system

The vacuum transfer pump system has a wide applications. Vacuum transfer system can be used for nearly all applications. The Vacuum transfer system is a 100% air driven system. It can generate high vacuum pressure for long distance suction up to 50 m. The max. transfer length is up to 1000 m. And as there is no rotating parts in the pump. The vacuum transfer pump system allows for high solids content cuttings and big size cuttings up to 170mm. As the vacuum pressure is huge, while the vacuum transfer pump unit is used to feed for the vertical cuttings dryer, there should be some device, like cleancut, between vacuum pump system and vertical cuttings dryer.

GN solids control brand decanter centrifuge with VFD control panel has been used by many big oil and gas drilling companies, mud service companies, drilling waste management companies. GN Solids Control equipment and the drilling waste management equipment have been exported to 74 countries and regions till now, like U.S.A, UAE, Saudi Arabia, Australia, Argentina, UK, Malaysia, Thailand, Singapore, Romania, Brazil, Egypt, Algeria, Qatar, Kuwait, Yemen, Russia, Sudan, Morocco, PNG, South Africa, Nigeria, India, Indonesia, Korea, etc…
GN Solids Control provides 2 options for variable speed control for waste management decanter centrifuge:
Option 1 is variable frequency drive (VFD).
Option 2 is full hydraulic drive control (FHD).

Normally GN Solids Control provide centrifuge with pressurized VFD control panel with air conditioner instead of FHD, the reason is as below:
1) VFD centrifuge is more convenient for maintenance and repair. Because the electric components in the VFD is standard models, most of them are from ABB/Siemens/Schneider brand, the users can source it locally if they need to replace some parts. But the FHD should be repaired by the manufacturer if it failed to work.
2) VFD centrifuge is much cheaper than FHD. Until now there is no many good manufacturer of the core components of the FHD, we have to import, which leads the production cost very high. VFD centrifuge is more popular because it is a cost-effective option.
3) GN Solids Control had noticed to fix the inverter and other electrical components inside the VFD control panel during shipment, so you can be rest assured that they will not be loosed or fall off during transportation.
4) GN Solids Control have protection inside the VFD for Voltage and Current instability when start the centrifuge, if the change of voltage/current is in a acceptable range, it will protect the inverter from being damaged.
