GN Solids Control is a Chinese company that specializes in the design, manufacturing, and service support of solids control equipment and waste management systems primarily for the oil and gas drilling industry. They are also a major player in the HDD (Horizontal Directional Drilling) and CBM (Coal Bed Methane) sectors.
The company is known for providing integrated solutions to separate solids from drilling fluid (mud), which is critical for efficient drilling operations, environmental protection, and cost reduction.
Key Products and Solutions
GN’s product line covers the entire solids control process, often referred to as the “mud system” or “mud tank system.” Their main equipment includes:
Shale Shakers: The primary and first stage of solids control. They use vibrating screens to remove large drill cuttings from the drilling fluid. GN offers various models, including linear motion and balanced elliptical motion shakers.
Vacuum Degassers: Used to remove entrained gases (like methane or hydrogen sulfide) from the drilling fluid, which is crucial for maintaining mud density and preventing kicks or blowouts.
Desanders & Desilters: Hydrocyclones that serve as the second and third stages of solids control. They remove finer sand and silt-sized particles that the shaker cannot capture.
Decanter Centrifuges: The fourth stage of solids control. These high-speed centrifuges separate ultra-fine particles and are also used for barite recovery (saving expensive weighting material).
Centrifugal Pumps: Used throughout the system to move drilling fluid between different pieces of equipment.
Mud Tanks & Agitators: Custom-designed tanks that hold the drilling fluid, with agitators to keep the fluid homogenous and prevent settling.
Complete Systems: GN integrates all this equipment into a single, skidded or trailer-mounted system, such as:
Mud Cleaning System: Typically includes shakers, degassers, desanders, and desilters.
Complete Solids Control System: Includes all the above plus centrifuges.
Slurry Separation System: For construction and piling projects.
Waste Management Units: Such as cuttings dryers and screw pumps for handling drill cuttings.
