GN SOLIDS CONTROL Supplies 10 Large-Bowl Decanter Centrifuges and 5 Vertical Cuttings Dryers for African Project

Topic: Integrated Drilling Waste Management Equipment for African Oilfield Operations

GN SOLIDS CONTROL has supplied a comprehensive package of solids control and drilling waste management equipment for an oilfield project in Africa. The shipment includes 10 GNLW453D-VFD large-bowl decanter centrifuges with supporting stands, 5 GNCD930G vertical cuttings dryer systems, 10 feeding pumps, and 10 screw conveyors, providing an integrated solution for drilling fluid recovery and waste handling.

High-Capacity Drilling Fluid Separation

The GNLW453D-VFD decanter centrifuge is designed to separate fine solids from drilling fluids through high-speed centrifugal force. Its large-bowl configuration provides effective processing capacity for demanding drilling operations, while the variable frequency drive allows operators to adjust rotational speed according to changing fluid properties and separation requirements.

Each centrifuge is supplied with a supporting stand to facilitate equipment installation and integration with the drilling fluid treatment system.

Efficient Drilling Cuttings Treatment

The GNCD930G vertical cuttings dryer is designed to recover drilling fluids from wet drilling cuttings, helping operators reduce residual liquid content and minimize drilling waste volume.

Working together, the vertical cuttings dryers and decanter centrifuges form a practical treatment process. The dryers separate recoverable fluids from cuttings, while the centrifuges provide further solids separation from the recovered liquid.

Integrated Material Handling and Feeding

The package also includes 10 feeding pumps and 10 screw conveyors to support continuous material transfer between processing stages.

The feeding pumps deliver drilling fluids to the separation equipment, while the screw conveyors facilitate the controlled movement of drilling cuttings and separated solids. This coordinated arrangement helps reduce manual handling and improve operational efficiency.

Supporting African Drilling Operations

With this equipment package, GN SOLIDS CONTROL continues to support international drilling contractors through reliable solids control technology and integrated waste management solutions.

From shale shakers and mud cleaners to VFD decanter centrifuges, vertical cuttings dryers, and complete drilling mud systems, GN offers a broad equipment portfolio for oilfield projects worldwide.

GN Solids Control Invite you to Beijing 2026 CIPPE Oil Show

We eagerly anticipate face-to-face interactions with you at CIPPE Beijing 2026, deepening our strategic partnerships, and jointly tapping into more vast development opportunities in the global oil and gas solids control sector!

GN Decanter Centrifuge and Cuttings Dryer for Africa Drilling Company

Vertical cuttings dryers and decanter centrifuges are core processing equipment used downstream of the drilling mud solids control system. After the shale shakers, desanders, desilters, and mud cleaners separate the coarse and medium solids from the drilling fluid, a significant amount of fine solids and liquid remains trapped in the drill cuttings. To meet environmental regulations, reduce drilling waste volume, and recover valuable drilling fluid, further treatment of these drill cuttings is required. Vertical cuttings dryers, together with high-speed and low-speed decanter centrifuges, play a critical role in achieving this objective.

The vertical cuttings dryer is primarily designed to treat drill cuttings discharged from shale shakers when drilling with oil-based or synthetic-based mud. By utilizing high-speed centrifugal force, the dryer effectively removes residual liquid from the cuttings, significantly reducing oil-on-cuttings (OOC) and producing drier solids suitable for disposal or further handling.

Meanwhile, decanter centrifuges are used to process the liquid phase recovered from the dryer, as well as overflow from the solids control system, enabling fine solids separation and efficient recovery of drilling fluids. High-speed centrifuges focus on ultra-fine solids removal, while low-speed centrifuges are applied for barite recovery and density control, ensuring optimal mud performance and cost efficiency.

GN Solids Control offers a complete range of high-quality vertical cuttings dryers and decanter centrifuges designed to meet the diverse technical, operational, and regulatory requirements of different markets worldwide. The equipment is engineered with robust mechanical design, wear-resistant materials, and reliable control systems to ensure stable operation in harsh drilling environments.

Recently, GN Solids Control successfully delivered one (1) vertical cuttings dryer model GNCD930G and two (2) variable-speed decanter centrifuges model GNLW363D-VFD to an African drilling company. The decanter centrifuges are equipped with electrical variable frequency drives (VFD), allowing precise adjustment of bowl speed and conveyor differential speed. This flexibility enables the centrifuges to adapt to various applications, including fine solids removal, barite recovery, and fluid clarification, under different mud types and operating conditions. The supplied system provides efficient cuttings treatment, reduced environmental impact, and improved overall drilling fluid management for the project.
