A shale shaker is the first and most critical solids control equipment in drilling operations. It removes large drilled cuttings (≥75μm) from drilling fluid using vibrating screens, allowing clean mud to be reused.

Benefits of GN Shale Shakers
✔ Superior Solids Removal – Extends the life of downstream equipment (desanders, centrifuges).
✔ Low Maintenance – Easy screen replacement & durable construction.
✔ Energy Efficient – Optimized vibration motors reduce power consumption.
✔ Compatible with All Mud Types – Water-based, oil-based, synthetic-based.
✔ Global Certifications – API RP 13C, ISO 9001, CE, ATEX (for explosive environments).

A mud cleaner is a 2-stage or 3-stage solids control device that removes medium to fine particles (15-75μm) from drilling fluid after the shale shaker. It typically consists of:

Shale shaker (for coarse solids removal)

Hydrocyclones (desander + desilter for finer separation)

Bottom sieve (optional, for ultra-fine recovery)

GN Solids Control supplies high-efficiency mixing hoppers (also called mud hoppers or jet hoppers) for fast and uniform preparation of drilling fluids. These are essential for blending bentonite, polymers, additives, and weighting materials into water or oil-based mud systems.

GN Solids Control Co., Ltd. is a Chinese company specializing in the design, manufacturing, and service of solid control systems and related equipment for the oil and gas drilling industry.

Mud Recycling System in Drilling Activity
A Mud Recycling System (also called a Solids Control System) is essential in drilling operations to remove drilled solids, maintain drilling fluid properties, and reduce waste. GN Solids Control Co., Ltd. provides advanced mud recycling solutions for oil & gas, HDD (Horizontal Directional Drilling), and geothermal drilling.

Key Components of a Mud Recycling System A typical GN mud recycling system includes:

1. Shale Shaker (Primary Separation) Function: Removes large cuttings (≥74μm) from drilling fluid.

GN Models: Linear motion / elliptical motion shakers.

Benefits: High G-force, fine mesh screens for better solids removal.

2. Desander & Desilter (Secondary Separation) Desander (40-100μm): Hydrocyclones remove medium-sized solids.

Desilter (15-40μm): Finer hydrocyclones for small particles.

GN Feature: Compact, high-efficiency hydrocyclone cones.

3.Degasser (Gas Removal) Vacuum Degasser: Removes entrained gases (H₂S, CH₄) from mud.

GN Feature: Automatic control for efficient degassing.

4.Centrifugal Pump & Mud Mixing System Ensures smooth fluid transfer and mixing of additives.

How the Mud Recycling System Works

1. Drilling Fluid Returns from the wellbore carrying drilled cuttings.

2. Shale Shaker removes large solids (primary separation).

3. Desander & Desilter remove finer particles (secondary cleaning).

4. Degasser eliminates harmful gases.

5. Recycled Mud is pumped back into the active mud system.

Benefits of GN Mud Recycling System
✔ Reduces Drilling Fluid Costs (up to 30% savings by reusing mud).
✔ Improves Drilling Efficiency (clean mud = better ROP, less wear).
✔ Minimizes Environmental Impact (less waste, compliance with EPA/IMO).
✔ Customizable (skid-mounted, containerized, or trailer-based).
✔ Suitable for All Fluids (water-based, oil-based, synthetic-based mud).

Applications
Oil & Gas Drilling (onshore & offshore)

HDD (Horizontal Directional Drilling)

Geothermal & Mining Drilling

Tunneling & CBM (Coal Bed Methane) Wells
