GN Solids Control Co., Ltd. is a Chinese manufacturer and global supplier of comprehensive equipment and systems for solid-liquid separation, primarily serving the oil and gas drilling, HDD (Horizontal Directional Drilling), and environmental industries.
Core Products and Services GN provides a full line of solids control equipment and integrated systems. Their product portfolio includes:
- The “Five Stages” of Solids Control Equipment:
Shale Shakers: The primary and first stage of solids removal. GN offers various models, including linear motion and elliptical motion shakers, with single, double, or triple decks to separate different sizes of solids.
Vacuum Degassers: Used to remove entrained gases (like methane or hydrogen sulfide) from the drilling fluid, which is critical for maintaining mud density and preventing kicks.
Desanders & Desilters: Hydrocyclones that remove fine, abrasive sand and silt-sized particles (15-50 microns and finer) from the drilling fluid. These are essential for protecting downstream equipment.
Decanter Centrifuges: A critical piece of equipment for the final stage of separation. High-speed centrifuges are used to separate ultra-fine solids and to dry out cuttings for waste minimization.
Mud Cleaners: A combination unit that typically integrates a desander/desilter hydrocyclone with a fine-screen shaker to process the underflow.
2. Additional and Auxiliary Equipment:
-
Centrifugal Pumps: GN manufactures their own robust centrifugal pumps for transferring mud between equipment.
-
Mud Tanks: Custom-designed and fabricated tanks with piping, agitators, and walkways.
-
Cuttings Dryers: Also known as “vertical centrifuges,” these are used to recover even more liquid from drill cuttings, significantly reducing waste volume and disposal costs.
-
Drilling Waste Management Systems: Complete solutions for processing drill cuttings, including drying, conveying, and packaging systems.
-
Mud Gas Separators (“Poor Boy Degassers”): For handling large volumes of gas-invaded mud.
3. Integrated Systems:
GN is known for building complete, skidded, or trailer-mounted solids control systems that combine all the necessary equipment into a single, compact package. These are popular for land drilling rigs, workover rigs, and HDD projects.
