Solids Control System: Key Components for Drilling Efficiency

A solids control system within the drilling program is an important but often overlooked part of the well construction process. Having an effective system in place minimizes overall operational costs by:

  • Helping lower fluid dilution rates
  • Reducing the volume of required additives
  • Improving drilling fluid/mud properties, allowing higher flow rates
  • Extending the life of the drilling fluid

Additionally, a sound solids-control system helps ensure environmental and regulatory compliance, an important issue in many regions today. KOSUN has been a trusted partner in solids control for over 30 years, providing reliable solids control systems to drilling operations worldwide.

The Solids Control System: Key Components

A solids control system contains many components, some of which are standard on the rig, while others are added for specific well conditions and drilling environments. However, the system must be the right fit for the rig and work efficiently with the operator’s drilling program. Each component must be evaluated for efficiency and to ensure it complements the existing rig system. For example, the centrifuges must be properly sized to match the fluid rates.

As solids progress through the drilling mud circulation system, the different components — such as shaker screens — separate and remove solids according to size. A well-designed system can remove most solids, down to the smallest particle. The re-conditioned, clean mud can be reused in the drilling process while the solids are hauled away from the wellsite and disposed. KOSUN’s comprehensive range of solids control systems ensures seamless integration and optimal performance at every stage.

Modern Solutions and Best Practices

Today’s solids control system may include instrumented surface measuring of the fluids system that provide automated monitoring of the circulating system and solids control equipment. If set up and managed properly, operators can get the most benefits from their fluids system and be sure that they have an effective system in place. The next phase in solids control is the introduction of a closed-loop system for increased environmental control and reduced risk of drilling fluid spills. A closed-loop  system can eliminate the need for a conventional reserve pit and can further reduce waste management costs.

KOSUN offers advanced closed-loop solids control systems that help operators achieve environmental compliance while improving operational efficiency. We design our solutions to adapt to diverse drilling conditions and meet regulatory requirements.

Best Practices for Operating Oilfield Mud Cleaning Equipment

Deep-well drilling requires precise surface fluid management. As drilling mud circulates through the wellbore, it returns carrying drilled solids, reactive clays, and abrasive sands. While shale shakers remove large cuttings, fine and ultra-fine particles often remain in the system. Mud cleaning equipment provides the secondary purification needed to remove these contaminants and maintain optimal mud performance.

Proper operation requires balancing fine-particle removal with the preservation of valuable drilling fluids and weighting materials. When managed correctly, mud cleaning equipment prevents the buildup of abrasive solids that accelerate wear on downhole tools, damage mud pumps, and reduce drilling efficiency.

Technical Performance of Mud Cleaning Equipment

Modern mud cleaning equipment combines hydrocyclones with a high-frequency vibrating screen to provide efficient secondary solids control while minimizing equipment footprint.

Drilling mud is pumped into hydrocyclones, where centrifugal force separates heavier solids from the fluid. Clean mud exits through the vortex finder and returns to the active system, while concentrated solids discharge onto fine-mesh screens for final separation. This two-stage process effectively removes harmful sand and silt while retaining valuable weighting agents such as barite.

Optimizing Throughput Capacity

Peak performance depends on maintaining stable feed pressure throughout the system. Treating the mud cleaner as part of an integrated solids control process—not as a standalone unit—is essential.

Low feed pressure weakens the cyclone vortex, allowing unprocessed slurry to overload the screen panels, reducing efficiency and increasing mud losses. Excessive pressure creates turbulence that carries fine solids back into the clean mud stream. Maintaining a consistent, calibrated feed rate ensures efficient separation and reliable system performance.

Preventive Maintenance

Hydrocyclones operate under continuous abrasive conditions and require routine inspection to maintain separation efficiency.

Operators should regularly inspect cone interiors for wear, erosion, and inlet blockages that disrupt flow patterns. The discharge apex should produce a hollow umbrella-shaped spray. A thick, solid discharge, known as “roping,” indicates an overloaded or plugged cone that requires immediate cleaning to prevent screen damage and reduced performance.

Maintaining Structural Stability

The vibrating screen basket plays a critical role in equipment performance and screen life. A heavy-duty frame evenly distributes high G-forces, reducing structural stress and minimizing vibration.

Screen panels must be properly tensioned and fully supported to prevent premature mesh failure. Maintaining the correct deck angle and selecting the appropriate screen mesh for formation conditions improves solids removal, extends screen life, minimizes fluid loss, and supports efficient closed-loop mud recycling.

Conclusion

Mud cleaning equipment is essential for advanced drilling fluid purification. By maintaining stable operating conditions, optimizing feed pressure, performing regular hydrocyclone maintenance, and ensuring proper screen installation, operators can maximize separation efficiency, reduce equipment wear, minimize downtime, and improve overall drilling performance.
