 drier shaker Some of our customers do the business of drilling waste management, the drier shaker is one of the main equipments in the drilling waste management system.
What is a Drier shaker
When talk about the drilling waste management, we always mention the vertical cutting drier which is used very popular in the system. Regarding the drier shaker, it is the same function with the cutting drier. And seeing from the out shape, it is same structure with the shale shaker, just with more higher force vibration motor and installed with more finer mesh screen.
How the Drier Shaker works
With the high vibration force, the water in the drilling cuttings could be uttermostly separated and through pass the mesh screen. The cuttings would be more drier, that would be easy to treat the cuttings in coming procedure. The fluids out from the drier shaker would be transfered to the centrifuge by a screw pump or slurry pump to separate the more finer solid particals.
Currently, GN could offer the drier shaker of model GNZS63-4. If you are interested in our drier shaker or other solids control equipments, just feel free to tell us.

GN shale shaker Shale shaker is one type major solids control equipment used in oilfield drilling, HDD or other drilling projects. Nowadays, the most advantaged shale shaker is the balanced elliptical shale shaker, while the most popular used is the linear motion shale shaker. What is the difference between the linear motion and balanced elliptical shale shaker. Let’s talk something about it.
As we known, the second generation shale shaker is Elliptical motion, the third generation is linear motion and the fourth generation is balanced elliptical motion. Many clients often regard the fourth generation as elliptical motion, however, that is an incorrect understading about it. Please refer the pictures below, you could find the difference of these two vibration mode:
 Linear Motion Linear motion shale shaker often apply 2 vibrating motor with same power, but the vibrating direction is opposit horizontal. At the vertical direction, the vibrating force produced by 2 motors will reduplicate. Thus the vibrationg mode is a linear and forward direction.
While on a Balanced elliptical shale shaker, the 2 vibrating motors are different in power, that results an unbalanced force counteracting. So the vibration mode will be like that (shown in below picture.)
 Balanced Elliptical Motion
The balanced elliptical shale shaker is a production from combination of commerce and science. GN BEM shaker won the National technology progress awards.
By now, we have exported many sets BEM shale shaker to our customers, if you want learn more about shale shaker or need a quote, just feel free to contact with us.

Shortly before, we received an inquiry for Mud Conditioner. At the moment we got this mail, we are confused for what is the mud conditioner, after one mail and a call to our client, we got to know that, they are in need of Mud Cleaner. In order to prevent the confusion between client and us, we are now talking about this equipments by the name of mud conditioner.

What Is Mud Conditioner
Simply Speaking, mud conditioner is a combination equipment of desander, desilter and Vibration screen. It is always used as the second and the third stage drilling mud cleaning equipment. The upper part of the mud conditioner is desander cone and desilter cone connected by pipeline system, also the pipeline worked as the frame structure. In our design, the size of the drilling mud inlet pipe is always 6″ while the outlet (also called overflow pipe) is 8″. The bottom part of the mud conditioner is a underflow shaker which we match 250 mesh fine screen on the shaker. The screen could be installed and uninstalled easily by inserting and drawing out the wedge block which is used to secure the screen. Continue reading »

People may find that in the previous blogs here, one statement is often mentioned that GN is a professional manufacturer of mud system for CBM. But what is CBM? We think maybe few people know it if not involved in this line.
What is CBM
CBM or coal bed methane is a type of natural gas produced from coal. The coal seam is both the source and the reservoir, which is different from conventional oil and gas.
The Formation of CBM
During the coalification process, some organic matter is converted into coal, while some other organic matter is transformed into natural gas, which is then adsorbed onto the surface of the coal. The methane stored is up to seven times the amount of natural gas stored in a conventional sandstone reservoir.
When the pressure of the coals at depth is released, the CBM produced. This process is called dewatering, for this occurs when water trapped within the coal is removed.
How People Develop the CBM
The challenge in developing CBM is to find ‘sweet spots’that allow gas to flow at commercial rates. These factors include gas content and saturation in the coal, the permeability of the coal, thickness of the coal seams and the areal extent.
A 300 to 1,200 metre deep well is used to extract CBM from the coal bed. A special rotating blade ream out cavities in the coal seams. Water, released from the coal, is pumped from the well then the gas separate from the coal and flow into the well. The water is transported through underground pipes to a dam for possible reuse and recycling. The gas passes through a separator near the well head to remove water traces before being piped to a processing facility to be compressed and dehydrated. The gas is then fed into commercial pipelines.

Cellar Pump, we could also call it submersible slurry pump, mud guzzler, trash pump etc. How should we call it all depends on where we are in the world. Cellar pump plaies an important role in HDD mud cleaning system. Today, let’s talk something about it.
 cellar pump
Location and Application of Cellar Pump
In a HDD (Horizontal Directional Drilling) project, the drilling mud overflowing from the drill hole is often guided into a mud pit or a lower tank which the drilling mud level is lower than the drilling mud cleaning equipments. Therefore, we need a device to transfer the mud from a lower place to a relative higher place, that is why we choose cellar pump. Cellar pump is used to transfer the drilling mud to the first stage mud cleaning equipment – shale shaker. To some extend, cellar pump is not one part of the complete mud cleaning system. It is a medium between the rig and mud system.
