Mud Cleaner in Oilfield Operations: Advanced Fluid Management Solutions by KOSUN

In modern oil and gas drilling, the quality of circulating drilling fluid directly affects operational efficiency, wellbore stability, and equipment life. As drilling projects move toward deeper, high-pressure, and complex formations, the generation of fine solids increases significantly. An advanced mud cleaner plays a critical role in removing these particles and maintaining optimal drilling fluid performance.
The oilfield mud cleaner combines secondary and tertiary solids control into a single compact unit, enabling high flow capacity and precise separation. Since 1992, KOSUN has been a leading manufacturer of drilling solids control equipment, providing high-performance mud cleaners and complete fluid management systems for global oilfield operations.

What Is a Mud Cleaner and Why It Matters?

A mud cleaner is an integrated system that combines:
 * Desander hydrocyclones (10–12 inch cones)
 * Desilter hydrocyclones (4 inch cones)
 * High-frequency linear motion shale shaker
This configuration allows drilling fluid to undergo centrifugal separation and fine mechanical screening in one process.
By installing a mud cleaner in a closed-loop circulation system, operators can:
 * Reduce drilling fluid loss
 * Minimize chemical and base fluid consumption
 * Maintain stable mud density and viscosity
 * Improve rate of penetration (ROP)
 * Reduce equipment wear and maintenance costs
The ability to recover expensive weighting materials such as barite makes the mud cleaner a key factor in controlling drilling costs.

Engineering Synergy: Hydrocyclone and Shaker Integration

The core advantage of a mud cleaner drilling system is its treatment of hydrocyclone underflow.
 Working process:
 * Drilling fluid is pumped into desander and desilter manifolds
 * Centrifugal force separates sand and silt from the fluid
 * The concentrated underflow drops onto a fine-mesh shaker screen
 * Usable liquid is recovered and returned to the active system
 * Only dry solids are discharged as waste
Without a mud cleaner, hydrocyclone underflow is often discarded, resulting in significant fluid and material loss. KOSUN mud cleaners maximize fluid recovery while maintaining precise solids control, improving both operational efficiency and environmental performance.

Optimal Placement in Drilling Rig Systems

In a typical mud cleaner in drilling rig configuration, the unit is installed:
 After:
 * Primary shale shakers
 * Vacuum degasser
 Before:
 * Mud tanks or suction tanks
 * Decanter centrifuge (if used)
This positioning allows the mud cleaner to act as a final polishing stage, removing harmful drilled solids while retaining beneficial added solids such as barite. Maintaining this balance is essential for controlling wellbore pressure and preventing excessive viscosity or equipment wear.
The performance of the system depends on proper feed pressure from centrifugal pumps. KOSUN engineers ensure hydraulic balance across the hydrocyclone manifold so that each cone operates at optimal efficiency, delivering stable and reliable separation.

Designed for Modern High-Precision Drilling

Horizontal wells, extended-reach drilling, and high-density mud systems generate large volumes of ultra-fine cuttings. To meet these challenges, KOSUN mud cleaners feature:
 * Wear-resistant polyurethane hydrocyclone cones
 * High-strength structural steel frames
 * Heavy-duty anti-corrosion coatings
 * High-G force linear motion shakers
 * Optional variable frequency drive (VFD) control for adjustable vibration
VFD technology allows operators to optimize cuttings dryness and fluid recovery based on mud properties and solids loading, improving both environmental compliance and operating efficiency.

Durability and Easy Maintenance in Harsh Conditions

Oilfield environments expose equipment to continuous vibration and abrasive slurry. KOSUN mud cleaners are built for long-term reliability with:
 * Multi-layer stainless steel shaker screens for high throughput
 * Replaceable cone nozzles and wear parts
 * Robust structural design for continuous operation
 * Easy inspection and maintenance access
Routine monitoring of discharge conditions and cone performance helps prevent issues such as “roping” or overloading, ensuring stable system performance and reducing non-productive time (NPT).
