In today’s era of increasing cost pressure in oil and gas development, the management of drilling fluid (mud) assets has become a critical factor determining project profitability. Drilling fluid costs typically account for 10% to 15% of the total drilling budget. A premium Solids Control System is not merely environmental equipment; it is the core profit center of the drilling site.

Expensive Mud Loss and Hidden Costs Induced by Harmful Solids Accumulation

During drilling operations, the mechanical shearing of rock cuttings leads to a large volume of ultra-fine particles entering the circulation. According to industry calculations by the International Association of Drilling Contractors (IADC), if these harmful solids are not promptly removed by an efficient Solids Control System, the density and viscosity of the mud will rise uncontrollably.

To maintain mud performance, operators are often forced to adopt the “dilution method”—discharging portions of high-sand-content mud and injecting large volumes of new fluid. This primitive approach leads to massive waste of expensive barite, polymer additives, and base oils. Research data suggests that for every 10% decrease in solids control efficiency, mud material expenditures for a single deep-well project increase by more than 15%. Furthermore, tool wear and pump damage caused by harmful solids significantly drive up spare parts replacement costs, creating a massive hidden economic burden.

Resource Recovery Mechanisms of High Efficiency Solids Control Systems for Project ROI

A scientifically configured Solids Control System achieves closed-loop circulation and resource recovery through physical separation, directly enhancing the Project’s Return on Investment (ROI). According to the American Petroleum Institute (API) specifications, efficient solids control workflows can recover over 85% of the base mud.

Through the synergistic operation of high-efficiency shale shakers and high-speed centrifuges, the system precisely controls the solids content in the mud. This not only reduces the cost of preparing new mud but, more importantly, significantly decreases the total volume of waste mud for disposal. Under increasingly strict environmental policies, the costs of waste transportation and third-party disposal have become non-negligible expenditures. An efficient Solids Control System achieves “reduction at the source,” transforming expensive waste into recyclable resources, thereby ensuring operational compliance while lowering Operating Expenses (OPEX).

KOSUN Expert Performance in OBM Drilling Waste Management System for Deep Recovery

As a leading global expert in solids control, KOSUN has been deeply rooted in the industry since 1992. Addressing the specific needs of Oil-Based Mud (OBM) recovery and “Zero Discharge” requirements, the KOSUN OBM Drilling Waste Management System demonstrates exceptional economic value. This system integrates high-efficiency Vertical Cuttings Dryers and high-speed Decanter Centrifuges, specifically designed to treat wet cuttings discharged from shale shakers.

The KOSUN Vertical Cuttings Dryer utilizes powerful centrifugal force to reduce the Oil on Cuttings (OOC) to below 5%. This means that expensive base oil, which would otherwise be discharged with waste, is extracted and recycled back into the Solids Control System for reuse. This deep liquid phase recovery capability, combined with a highly modular and compact design, not only saves customers massive expenditures on mud raw materials but also significantly reduces logistics costs for rig moves and waste transport. With over thirty years of field experience, KOSUN is empowering global partners to maximize profits through its expert-level processing technology.

In drilling operations, treating gas-cut mud caused by well kicks is a critical link in ensuring well control safety and maintaining mud performance. The drilling fluid vacuum degasser manufactured by KOSUN provides a reliable gas treatment solution for construction sites through its mature negative-pressure separation process and compact structural layout. 

Negative Pressure Self-Priming Structure of the Vacuum Degasser 

The KOSUN Vacuum Degasser adopts the industry-mainstream self-priming structure. Its core principle involves using a vacuum pump to extract gas from a sealed separation vessel, creating a significant pressure differential. Driven by atmospheric pressure, the mud automatically enters the vessel through the suction pipeline without the need for an additional centrifugal feeding pump. This compact layout reduces investment in auxiliary equipment and simplifies pipeline connections. It is particularly suitable for space-constrained operating environments, effectively minimizing potential system failure points. 

Eliminating Corrosion Hazards and Reducing Maintenance Costs 

Upon entering the vessel, the mud is sprayed and agitated by a high-speed rotating impeller. In a low-pressure environment, bubbles within the mud are rapidly ruptured, achieving swift separation of free gases. Through efficient degassing, this drilling fluid vacuum degasser eliminates cavitation damage to mud pump liners, pistons, and centrifuge bearings caused by gas intrusion. Simultaneously, the separated gas enters a water-gas separator; certain harmful gases are dissolved in water for treatment, while the rest are discharged safely. This process reduces the corrosion of pipelines and metal tanks by acidic gases, directly lowering repair and maintenance costs. 

Compact Design Optimizing Tank Surface Space Utilization 

To meet the strict requirements for equipment footprint at modern well sites, the KOSUN Vacuum Degasser has been structurally optimized. The overall design is compact, occupying minimal space. On the mud tank surface, this streamlined layout leaves more room for other solids control equipment while making lifting, transportation, and onsite installation more convenient and efficient. 

Dual-Purpose Functionality: Serving as a High-Power Mud Agitator 

The KOSUN drilling fluid vacuum degasser was designed with integrated utilization in mind. Under non-gas-cut conditions, due to its powerful internal circulating and spraying capabilities, the Vacuum Degasser can also function as a high-power drilling mud agitator. By continuously circulating the mud within the tank, it effectively prevents the settling of solid particles and ensures stable mud properties, achieving multi-functional value for a single unit across different working conditions. KOSUN focuses on enhancing product durability and field applicability. Through rigorous negative-pressure degassing processes and stable power performance, we are committed to providing global customers with solids control equipment that meets industry standards and delivers significant economic benefits. 

With global oil and gas environmental regulations becoming increasingly stringent—targets like “Zero Discharge” and “Cuttings Containment” in the North Sea, Gulf of Mexico, and China are now mandatory—building an efficient Drilling Waste Management (DWM) system is essential. In this complex closed-loop process, the centrifugal sand pump

, responsible for efficient slurry transfer, is the core equipment ensuring continuous operation and regulatory compliance.

Centrifugal Sand Pump Ensures Stability of the Environmental Treatment Chain

A cuttings management system must pump oil-based or water-based cuttings from collection points to vertical dryers, thermal desorption units, or stabilization units. This is a high-wear, high-load continuous process. Any failure—especially in the centrifugal sand pump—can interrupt the entire workflow, leading to severe environmental non-compliance risks and financial penalties.

The KOSUN centrifugal sand pump is engineered for these harsh environments. Its heavy-duty horizontal design focuses on reliability under extreme conditions. The rugged construction and specialized wear-resistant carbide mechanical seals ensure long-term stability when conveying highly abrasive and viscous materials, significantly reducing downtime for maintenance.

Core Technology: How the Centrifugal Sand Pump Supports Green Drilling

The design features of a high-quality centrifugal sand pump directly serve environmental goals:

Efficient Transfer Capability: It ensures cuttings are moved from the rig site to processing equipment without delay or accumulation, preventing secondary pollution. Thanks to unique closed impeller and back vane designs, this centrifugal sand pump offers higher head and consistent efficiency.

Corrosion and Wear Resistance: By utilizing specialized materials to handle the erosive challenges of different base muds (OBM or WBM), the centrifugal sand pump maintains performance over long-term use, meeting the strictest environmental operational standards.

Expanding the Application Scenarios of the Centrifugal Sand Pump

Beyond waste management, the centrifugal sand pump plays a versatile role across the entire drilling fluid circulation system:

Feeding Solids Control Equipment: It serves as a stable feeding pump for desanders and desilters hydrocyclones.

Mud Charging and Mixing: The centrifugal sand pump can be used as a pre-charging (supercharging) pump for main mud pumps to prevent cavitation, or in conjunction with jet mixing devices for rapid mud preparation.

Long-Distance Transfer: With its high-head design, this centrifugal sand pump easily handles mud transfer between different tank areas and long-distance conveyance tasks within the well site.

KOSUN centrifugal sand pumps, specifically designed for oilfield applications, provide the reliability and durability needed for safe, compliant, and sustainable drilling. They are the cornerstone for oilfield enterprises to fulfill social responsibilities while enhancing operational efficiency.
