GN Solids Control is a leading Chinese manufacturer and global supplier of solids control and drilling waste management equipment for the oil & gas, HDD (Horizontal Directional Drilling), and tunneling industries.

Core Products and Services GN’s product line covers the entire process from fluid purification to waste handling. Their equipment is essential for maintaining drilling fluid properties, reducing costs, and meeting environmental regulations.

1. Solids Control Equipment (The “Five Stages”) This is their primary focus. The standard progression of equipment on a drilling rig is often referred to as the “mud system.”

Shale Shakers (1st Stage): The primary and first line of defense. They use vibrating screens to remove the largest drilled solids from the drilling fluid returning from the wellbore. GN offers various models, including linear motion and balanced elliptical motion shakers.

Vacuum Degassers (2nd Stage): Remove entrained gases (like methane or H₂S) from the drilling fluid, which is critical for maintaining fluid density and preventing kicks or blowouts.

Desanders & Desilters (3rd & 4th Stage): Hydrocyclones that use centrifugal force to remove finer sand and silt-sized particles. Desanders handle larger fine particles, while desilters remove the smallest ones.

Decanter Centrifuges (5th Stage): High-speed rotating machines that separate ultra-fine solids (down to the micron level) and barite (a weighting agent) from the liquid. This is crucial for recycling valuable barite and drying out waste.

2. Drilling Waste Management After separation, the solids need to be handled.

Vertical Cutting Dryers: Further dry the drill cuttings from the shale shakers, recovering more valuable drilling fluid.

Screw Presses: A continuous, low-maintenance dewatering device that squeezes water out of slurries, creating a drier, more manageable solid cake.

Slurry Pumping Systems: Transfer waste slurries between equipment.

Skip & Box Systems: Containers for collecting and transporting dried cuttings and waste.

3. Integrated Systems GN is known for building large, pre-fabricated systems that combine all the above equipment into a single, compact unit.

Mud System Skids: Custom-built systems that integrate shakers, degassers, desanders, desilters, and centrifuge pumps onto a single skid for easy transportation and rig-up.

Modular Plants: Larger, containerized systems for major drilling projects.

Key Features and Strengths
Global Presence: GN has a significant international footprint with offices, agents, and service centers in key oilfield regions worldwide (North America, Middle East, Europe, Asia, South America, Africa).

Strong R&D: They invest heavily in research and development to improve the efficiency, reliability, and automation of their equipment.

Competitive Pricing: Like many Chinese manufacturers, they often offer cost-competitive solutions compared to Western counterparts, without necessarily sacrificing quality.

Customization: They are known for their ability to design and build custom solutions tailored to specific client needs, well conditions, and rig space limitations.

One-Stop Shop: A client can source an entire solids control and waste management package from a single supplier.

GN Solids Control is a leading Chinese manufacturer and global supplier of solids control and drilling waste management equipment for the oil & gas, HDD (Horizontal Directional Drilling), and tunneling industries.

Industries Served
Oil & Gas Drilling (Onshore & Offshore)

Horizontal Directional Drilling (HDD) for pipelines and utilities

Tunneling and Geothermal Drilling

Environmental Remediation (e.g., slurry wall drilling)

Key Features and Market Position
Cost-Effective Alternative: GN is often positioned as a high-quality, more affordable alternative to Western premium brands like MI-SWACO (a Schlumberger company) and Derrick.

Global Reach: They have a significant international presence, with equipment operating in every major oil and gas region, including North America, the Middle East, Asia, Europe, and Africa.

Focus on HDD and Tunneling: While strong in oil & gas, GN has successfully tailored its equipment for the HDD and tunneling industries, where space and efficiency are paramount. Their smaller, skid-mounted systems are very popular in these sectors.

Strong Online Presence: GN is known for its effective use of digital marketing, making their products and information easily accessible online.

About the jet mixing unit,A Jet Mixing Unit, also known as a Mud Mixing Hopper or Jet Hopper, is a fundamental piece of equipment in any drilling fluid (mud) system. Its primary purpose is to efficiently and uniformly mix dry, powdered additives (like Bentonite, Barite, polymers, and chemicals) into the liquid phase (water or oil) to create and maintain the drilling mud.

How a Jet Mixing Unit Works
The operation is based on the Venturi Effect:

Pumping: A centrifugal pump (often a dedicated “mixing pump”) takes suction from the active mud tank and discharges a high-pressure stream of fluid.

Venturi Action: This high-pressure stream is directed through a nozzle inside the hopper, creating a high-velocity jet and a zone of low pressure (a vacuum).

Induction & Mixing: The created vacuum sucks the dry powder from the hopper’s bowl down into the throat of the educator. The high-velocity jet shears and instantly hydrates the powder particles, preventing them from clumping together into “fish eyes.”

Discharge: The mixed slurry is then discharged directly back into the mud tank.

In essence, the Jet Mixing Unit is the “kitchen” of the drilling fluid system. It’s where the “recipe” for the drilling mud is prepared. GN Solids Control provides reliable and efficient jet mixing hoppers that are a crucial first step in the process of creating and maintaining the high-quality drilling fluid essential for a safe, efficient, and successful drilling operation.

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:

1. 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.
