GN Solids America LLC manufacture oil drilling equipment including shale shakers and its wear and tear  parts. Shale shakers is the solids-filter machinery that remove drill cuttings from the drilling mud that is used for digging holes into the earth. Filtering the solids in drilling mud is an important component of the operation cost of drilling, so research and development into shaker functioning is ongoing.

GN Solids America’s shale shaker design – Shale shakers consist of large, flat wire mesh screens for  filtering or sieves of various mesh sizes that shake or vibrate the drill cuttings.  The commonly filter across and off of the shale shaker screens as the drilling fluid (mud) flows through them and back into the drilling fluid system. This separates the solid drill cuttings from the fluid so that it can be re-circulated back down the well bore for keep the drill bit functioning.


Poor boy degasser’s design purpose is for treating big volume of dissolved gas in the drilling mud. Such gas under the pressure will be expand if not take care it properly.  The poor boy degasser in traditional throttle pipe and between the vibrating screen and it has a direct discharge of gas pipeline. The installation of poor boy degasser is  typically installed in the rear of the throttle manifold.

The poor boy degasser needs meet the following operation needs:

  • Through field operation feedback, the capacity of gas process on poor boy degasser need to be five time as much as the design cycle.
  • The inner diameter of the pipeline need to be same or larger than the coke manifold in the inlet pipeline of the poor boy degasser.
  • The drilling fluid is directly discharged into the inlet manifold of the vibrating screen or the reserve tank of the drilling fluid.
  • The diameter of the exhaust should be 8 inches or greater.
  • The valve should not be installed on the gas discharge line.

Poor boy degasser parameters:

  • The gas from the separator must be firmly fixed.
  • During the cold weather the poor boy degasser installed on the bottom of the cleaning valve, in order to prevent liquid from blocking the liquid gas separator, the valve should be opened.
  • It need to be clean and maintain the poor boy degasser according to the specification or service provided by the manufacture

Each and every year, we will update our brochure, just before the CIPPE exhibition in March. Now here comes the 2017 edition.
Do not worry, we stick with our principle, quality first, price second, and as the first API certified solids control company, every year, API have anual inspection, and we passed.
  • Keep our principle, quality first
  • Keep cooperating with top quality parts suppliers
  • Keep focusing on the global market
  • Certified by API / ISO, HSE, CP-TU, CE… etc
As a developing company, a lot of things also have been updated, hope something interests you.
  • We built the new shaker screen factory, now capacity upto 8000pcs per month
  • New products released: GNLW764, 30inch big bowl centrifuge; TDU, thermal desorption unit for waste mangement; FHD centrifuge, the GNLW363C-FHD
  • Lots of equipment have been updated to the new version, which means, details have been improved. Thank you very much for your feedback if you did, or you whatever you will let us know in future. Now shale shaker have updated to the 6th type, overall dimension, shaker screens is replacable with Swacom Mongoose, we also have our new shaker GNZS703F series updated.
Hmmm, if you come to the booth, you will learn more about all the NEWS.
Keep tune…
As a leader of solids control equipment manufacturers in China, GN keep investing on new products, and as keep providing good quality products, built our international brand name. In the past 2016, GN have made some quite new products which we did not manufacture before: the centrifugal degasser, and the vacuum transfer pump.
Couple weeks ago, GN finished the fabrication of centrifugal type degasser, this enriched GN’s production line. This centrifugal degasser is designed and manufactured after researching many types of degassers home and abroad. It could be used in all kinds of drilling fluids recycling system to remove the gas in the gas cut-in drilling fluids for recovering the mud property, stabilizing mud viscosity and reducing drilling cost.
After a few project, keep buying the vacuum transfer pump, we finally decided to do some research and development on our own vacuum transfering. With our partners help, we finish and test it on site with good performance.
What we keep improving
Shale Shaker
One of the weakeness of Chinese shaker is we do not have a small sump underneath to make the fluids more flexible, to be able to flow to sides of the shakers, which also supposed to make things easier when design the mud tanks with mud ditch to easier balance mud flow. Now here it comes, we will show this type shakers in this exhibition, more details pls chase with our sales team.
Decanter centrifuge is our main products, and keep improving, each and every year, it is also a highlight to our competitors even.
If you are interested in more infomration, keep tune.

GN Solids Control is a world famous company and brand in the solids control and waste management industry. Now its business range spanning from shale shakers, mud cleaners, decanter centrifuge, cutting dryer, vacuum degasser and so on. GN could be your one stop shop in the solids control and drilling waste management area. Its product application covers from oil and gas drilling, HDD and CBM drilling, bored pile and TBM drilling.

Today I will introduce two more naming rules to you, mud gas separator and screw conveyor. As these two products are widely used in the oil and gas drilling system, there are more and more customers showing their interest in them. So understanding the naming rules is very important and could help you select the products effectively and efficiently. Let’s start with the mud gas separator: GNZYQ1000A,GN means the company name in short. ZYQ means thename of mud gas separator in Chinese in short. 1000 means inner diameter of the mud gas separator is 1000 mm.A means this product is the first generation, and in future, GN will make more upgrades and improvements for the mud gas separator, there will be B, C etc. and more versions coming out. The mud gas separator is also called “poor boy degasser” which means it’s more economic than the vacuum degasser, but it’s just working under the mechanical crashing power to separate the cut gas from the mud without the vacuum pump.


Next let’s go to the screw conveyor: GNSC14A-24,GN means the company name in short, SC means the product name screw conveyor in short.14means the diameter is 14 inch. A means it is the first generation. 24 means the length of the screw conveyor is 24 feet. Screw conveyor is widely used in the drilling wastemanagement system to transfer the cuttings for final disposal.

That’s the basic introduction of the naming rules formud gas separator and screw conveyor. Hopefully it will be useful to you.We will try our best to assist your business to be successful. Welcome to visit and please send your inquiries to
