As long as there is a drilling project, there must be a solids control system coming along, no matter it is for land rig drilling or offshore drilling far in the oceans, an efficient solids control system are vital for the drilling fluids recycling and drilling cuttings transportation, especially for the offshores.

GN SHAKER

GN SHAKER AND MUD CLEANER FOR OFFSHORE

In offshore projects, cause of the distance from the land, all material must be used to the most, the most liquid should be reused and least cuttings to be transported back to land. The shaker is used for separating out the most of solids, for handling the heaviest burden, the high performance and strong structure of shaker is quite important. Following features of GNZS series shakers ensures the shaker’s quality and performance:

1. A high G force up to 8.5G powered by Oli Vibrator for a good separation work.

2. Stainless steel shaker deck is stronger for handling the high G force.

3. Patent design of rubber sealing, effectively avoided the leaking of mud.

4. Two different models, with 3 or 4 pieces of shaker screens, providing large treating capacity of 120cbm/hr or 140cbm/hr.

5. Special patented way for changing screens, safe and human oriented.

Talking about shaker screens, as is known to all, shaker screens’ quality greatly affects the shaker’s performance. That’s why GN has built up a separate screen factory for better control over screen quality. In this shaker screen factory, GN is the first and only one who uses robot for welding and cutting, and GN’s screens are in accordance with API RP 13C, an accurate API number and a high conductance with a good screen frame structure made of composite material.

In order to meet customers’ request and to help solve the problems faced in front of customers from the more and more strict environmental protection rules, GN Solids Control designed and put into market a comprehensive design for the oily sludge separation unit, and now GN Solids Control is leading in this industry.
In recent 3 years, GN Solids Control has customized several sets of similar systems, and such systems are being used in many different countries both in domestic China and overseas. It is widely used for treating the discharged slurry and sands from crude oil tank cleaning, oily waste discharged from refineries, and the viscosity oily waste from solids control for oil and gas drilling. It helps to reduce the cost for waste transportation and oil recycle, and gained good comments from under users.

OILY SLUDGE SEPARATION

A complete system is combined by several sections:
1. Pre heating and pre mixing system. In this system, a mixing tank with heating facilities are being employed. A chemical dosing system is used for adding some polymer or something else into the oily sludge and heating is used for reducing the viscosity. Later, the sludge is to be treated by a shale shaker, by which the large particles are separated out.
2. A high speed decanter centrifuge is used in next step for treating out the fine particles from the liquid. Floating unit is kind of oil water separation, and the light of weight oil will float on surface of liquid and it would be scraped out to an oil tank. The settled down particles would be drained from bottom of the IPC unit.
3. A disc centrifuge is used to separate out the small amount of particles from the liquid, and further separate the oil from water. Then the water flows into the water tank, while oil flows into the oil tank.
In the complete system, by using the complicated manifold and valves, the end user can bypass or invite into loop some equipment based on the sludge’s condition.

It is a common knowledge that in the solids control system for a drilling rig, no matter for the land rigs or for the offshores, the shale shaker plays the most important role for separating out the solids waste from the mud recycling unit, and it is also the shale shaker which waste the most of the liquid on the cuttings discharged from the shaker. That’s why, in many countries, there is a must to equip another drilling cuttings treatment system alongside the rig.
A drilling cuttings waste management system is used for further separation of the drilling waste discharged from the shale shaker and mud cleaner, most of which are from the shakers. For one thing, the drilling cuttings waste management system helps to dry the cuttings for later transportation, on the other hand, it increased the drilling liquid amount to be recycled. Both are saving money. In case of OBM mud, the operators always need a vertical cuttings dryer and a high speed decanter centrifuge, while for WBM mud, operators always use a high G drying shaker and a decanter centrifuge.
In some cases, the ViST Shaker screen device could replace the drilling cuttings waste management system, or at least to some degree, reduced the work for the cuttings separation works. Generally speaking, the ViST shaker screen device has following advantages:

ViST shaker device

1. It is suitable for both WBM and OBM mud in a solids control system.
2. It is a compact structure, and only use an air compressor as power source, and one set of ViST could serve up to 3 sets of shale shakers.
3. It is designed to be suitable for different shaker models.
4. In practice, it helps to save the liquid amount by 30% to 50%.
Now for GNZS703 and GNZS594 series shale shakers, there are ViST device for option.
