DWM control Hi-G dryer of reliable performance

It is well known that shale shaker is always used as the first stage treatment equipment both in solids control system for oil and gas drilling and drilling mud system for other kinds of drilling such as HDD, CBM and so on. It will separate the coarse solids out, and then the liquids will be delivered to cyclones for second and third stages treatment.

While normally the solids discharged from the shake shaker and cyclones is not dry enough to be thrown directly under the much more strict environmental regulations. So drilling waste management equipment is required to dry the solids. Besides vertical cuttings dryer for both oil-based mud cutting and water-based mud cutting, Hi-G dryer shaker is also can be used to treat water-based mud cuttings with a G force up to 8.0.

KOSUN Hi-G shaker has 4 pieces screens to acquire a large treating capacity. With Italy Oil or Martin shaker motors and stainless steel bottom deck, KOSUN Hi- G dryer shaker enjoys a reliable and stable performance in a High G force after heat treat.


Besides, KOSUN shale shaker with high API screens always used as the bottom drying shaker for desander cyclone, desilter cone. So the solids out from the cyclones will fall into the shaker screen for drying and also to collect more useful and clean mud. Generally 2 model of bottom shaker are optional. The first one has 2 screen with a relatively small treating capacity to save cost; the second one has 3 screens with relatively larger treating capacity. While sometime a mud cleaner will be chosen with bottom shaker screen to save space and cost. KOSUN vertical cutting dryer is used to treat oil-based mud cuttings, but KOSUN cuttings dryer can also treat water-base mud cuttings.

Five tips on maintenance of poor boy degasser

Five tips on maintenance of poor boy degasser:

1. Open the screw plug for sand discharge in the manifold side to remove sand when the mud discharge manifold is blocked.

2. The separator assembly is pressure container,so it must be used in designed working pressure and surrounding. Overpressure work is forbidden. The safety valve should be checked at least once a year.

3. The baffle should be checked after a well has been completed. Replace it if there is something wrong.

4. Welding on the separator assembly is forbidden.

5. The exhaust pipe and liquid discharge pipe should be arranged separately when the separator is paralleled. Uniting the pipe is forbidden .


Mud gas separator is commonly called a gas-buster, poor boy degasser and liquid gas separator. It captures and separates large volume of free gas within the drilling fluid. If there is a “KICK” situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates.

Drilling security equipment mud/gas separator instruction

Drilling security equipment plays a vitally important role at drilling sites. In case of blowout or well kick, or when operators use unbalanced mud column in well drilling, mud/gas separator is essential. North American oilfields have the highest standards for security equipment in the world, and few security equipment of Chinese brands can enter American market and be put into service to support the drilling operations.

Mud/Gas Separator serves as an ideal device if well blowout or kick is encountered or if operators apply under-balanced mud column in drilling processes. KOSUN Mud/Gas Separator is primarily used to remove the enormous free gas from drilling fluids, including poisonous gases like H2S. Field data shows it is a fairly reliable and vital safety equipment.

Drilling security equipment mud/gas separator instruction:

1. Install and fix separator on the special base or hard and horizontal ground. To keep it stable, tighten it by ropes whose ends are inserted into ground.
2. In order to reduce the frictional resistance the min. Internal diameter of exhaust manifold should be no less than 250 mm.
3. Fixation is necessary while install pipe manifold. Connection of pipes should strictly accord with the installation drawings.
