After few months’ documentation preparation and request following up, GN finally was awarded the tender of solids control equipment for 16 drilling rigs in Ukraine. Client is planning to upgrade the existing mud recycling system by replacing the old equipment. This tender includes over 30 units decanter centrifuges, over 30 units shale shaker and mud cleaners, as well as 6 units vacuum degassers.
Below pictures shown is the second batch equipment ready for delivery.

Shale shakerand mud cleaner are the equipment use to remove the large size drilling cuttings in the drilling fluids. GN’s shale shakers model of GNZS594E-HB which is especially designed for the oil and gas drilling with weir feeder to buffer the high pressure impact for protecting the shaker screen. The screen deck of the shaker is adjustable from -1°to +5°,operator could even adjust the shaker deck during running of the shaker. With the G force up to 7.5, the shaker could greatly dry the solids for drilling fluids recovering. The cyclone manifold is bolted fixing on the shaker unit and could be removed for easy transportation and installation.

Vacuum degasserunit is installed after the shale shaker and before the mud cleaner. It is used to remove the gas in the gas cut in drilling fluids. By removing the gas, the vacuum degasser could ensure the drilling fluids with a proper gravity. And the centrifugal pump could transfer the drilling fluids to the cyclone unit with sufficient pressure.

Decanter centrifugeis used to remove the fine solid particles in drilling fluids. The client equipped 2 unit centrifuges for each of the drilling rig. When drilling, the decanter centrifuge with low speed could be used for barite recovery, and the other centrifuge with high speed would be used for ultra-fine solids separation.

The ordered equipment is the tender would be divided into 4 batches for delivery. The remaining units are still under fabrication progress. Please pay attention on GN solids control for latest news on delivery of this order.

Mud Gas Separators and PLC Waste Collection Container for Sinopec

As professional manufacturer for solids control and waste management equipment, GN has been praised by many world famous oilfield servicer . After back from the holiday of China’s National Day, GN finished the order from Sinopec about mud gas separators and waste collection containers.

Mud gas separator should be manufactured according to the API and ISO standard, usually used for drilling in underbalanced conditions where dramatic pressure surges normally. GN’s mud gas separator is with simple design structure of several baffle plates welded in the inner wall of the vessel for gas cut mud hitting on the baffle plates for dispersion good, make the gas separated. Normally, the separated gas will be guided to an open area for burning by an ignition device to keep safe work .

In this time, waste collection containers are used to collecting the drilling waste cutting or other waste stuffs on drilling site or oilfield. GN’s engineers had sufficient communication with client on the specifications requested of the container before manufacturing.

The main features of the waste collection containers:
1. Have excellent interface sealing – Can prevent the leaking of the liquid from the container, the sealing uses anti-corrosion silicone rubber.
2. On-line monitoring system – Leaking monitoring device installed at the discharge port
3. Loading warning system – The containers are equipped with gravity sensor module to avoid over loading as per relative environment protection regulation.
4. Internal coated with corrosion resistance for acid and alkali corrosion.
5. Electrical automatic sliding cover performs well on sealing for leakage when closed.
6. All cables are laid inside the square steel tubes; no any cables are outside, which is good for long lifetime and working safety.

To provide the qualified products to client, GN solids control is committed to technical improving and quality controlling. GN has standard production line for client to choose, also GN is able to provide customized solution based on mutual communication.
