Oilfield Drilling Mud Tank System & Custom Layout Solutions

In modern oil and gas drilling, the performance of the surface circulation system plays a critical role in wellbore stability, equipment protection, and overall drilling efficiency. At the center of this system is the drilling mud tank layout, which determines how drilling fluid flows through each stage of separation, treatment, and conditioning.
A well-designed mud tank system ensures that abrasive solids and entrained gases are removed before the fluid is recirculated downhole. This process maintains proper mud properties, reduces equipment wear, and supports higher rates of penetration (ROP).
Since 1992, KOSUN has specialized in the design and manufacturing of drilling mud tank systems and complete solids control equipment, providing reliable and customized solutions for oilfield operations worldwide.

What Is a Drilling Mud Tank System?

A modern drilling mud tank system is not simply a group of storage containers. It is a fully integrated processing unit where multiple separation and conditioning technologies work together, including:
 * Shale shakers
 * Desanders and desilters
 * Mud cleaners
 * Vacuum degassers
 * Centrifugal pumps
 * Mud agitators and mud guns
 * Jet mud mixers
Through a carefully planned tank sequence, drilling fluid is cleaned, mixed, and conditioned to maintain the required density, viscosity, and rheological properties for different drilling conditions.
 

Primary Separation: The Mud Shaker Tank

The circulation process begins at the mud shaker tank, where drilling fluid returning from the well first enters the surface system.
Key design features include:
 * Reinforced tank structure to support high-frequency shale shaker vibration
 * Efficient drainage to allow filtered mud to flow quickly into lower compartments
 * Sand traps or bypass systems for maintenance flexibility
 * Immediate removal of large cuttings to prevent downstream overload
KOSUN mud tanks are manufactured using high-precision welding and heavy-duty structural design to ensure long-term reliability and leak-proof performance under harsh operating conditions.
 

Fine Solids Control: The Mud Settling Tank

After primary separation, the fluid flows into the mud settling tank, where flow velocity is reduced to allow finer particles to settle naturally.
This tank typically includes:
 * Internal baffles and weirs to increase fluid residence time
 * Serpentine flow paths to improve gravity separation
 * Proper suction positioning for centrifugal pumps
At this stage, desanders and desilters (hydrocyclones) are usually installed to remove medium and fine solids. The cleaned overflow returns to the tank, while concentrated solids are discharged to waste.
Proper design of suction depth and pump placement is essential to avoid reintroducing settled solids into the system—an area where KOSUN engineering expertise ensures high-efficiency fluid recovery.
 

Critical Stage: The Mud Suction Tank

The mud suction tank is the final stage before drilling fluid is pumped back downhole by high-pressure mud pumps. Fluid cleanliness at this point is crucial, as even small amounts of sand or air can cause severe damage to pump liners, valves, and drilling tools.
 Modern suction tanks are equipped with:
 * Vortex breakers to prevent air entrainment and cavitation
 * Mud agitators and mud guns for uniform mixing
 * Chemical and weighting material addition points
 * Dead-zone-free design to maintain consistent mud density
KOSUN engineers focus on optimized internal layouts to ensure uniform fluid properties throughout the tank and stable pump performance.
 

Integrated System Design for Flexible Operation

The true value of a professional manufacturer lies in system integration. A high-quality mud tank system includes a network of:
 * Interconnecting pipelines and manifolds
 * Transfer valves for flexible fluid routing
 * Reserve and mixing compartments
 * Equipment mounting platforms
Operators can easily transfer mud between tanks, perform mixing operations, or isolate sections for maintenance without interrupting drilling.
KOSUN also provides optional automation features such as:
 * Level monitoring systems
 * Remote control valves
 * Centralized monitoring for safer and more efficient operations
 

Durability, Protection, and Easy Maintenance
 
Drilling fluids are often corrosive and abrasive, which can shorten equipment life if tanks are not properly protected. 
KOSUN mud tanks feature:
 * High-performance anti-corrosion epoxy coatings
 * Smooth internal surfaces to prevent mud buildup
 * Abrasion-resistant materials in high-wear areas
 * Designs that simplify cleaning during mud changes
These features extend equipment life and reduce maintenance downtime.
