Diamond core drilling projects often operate in remote areas where access to stable electrical power is limited and operating conditions can change rapidly. For these challenging environments, GN Solids Control has delivered three packages of hydraulic drive mini centrifuge units designed to provide reliable solids separation with maximum operational flexibility.

Unlike conventional electrically driven centrifuges, these units are powered through a diesel-driven hydraulic power system. The diesel power pack supplies hydraulic oil to a hydraulic motor, which then directly drives the decanter centrifuge. This drive configuration significantly reduces dependency on electrical infrastructure and makes the system especially suitable for off-grid drilling locations.

One of the main advantages of hydraulic drive technology is its ability to deliver high torque at low and variable speeds. In diamond core drilling, drilling fluid properties and solids loading can fluctuate as drilling progresses through different formations. The hydraulic motor responds smoothly to these changes, maintaining stable centrifuge operation and protecting mechanical components from overload or shock.

The mini centrifuge units are designed with portability and ease of deployment in mind. Their compact structure allows them to be transported alongside drilling rigs and quickly installed at site with minimal civil preparation. This is particularly important for exploration drilling projects that require frequent relocation as new boreholes are drilled.

Operational control is another area where hydraulic drive systems offer clear advantages. Centrifuge speed and differential torque can be adjusted by regulating hydraulic flow and pressure, allowing operators to fine-tune separation performance without complex electrical controls. This straightforward control method simplifies training requirements and reduces the risk of operational errors in the field.

From an efficiency standpoint, the hydraulic drive mini centrifuge plays a vital role in improving overall drilling fluid management. By removing fine solids from the drilling fluid, the system helps maintain consistent fluid properties, reduce wear on drilling tools, and extend the service life of downstream equipment. Recovered drilling fluid can be reused, reducing both water consumption and waste disposal volumes.

Durability is a key design consideration for GN’s hydraulic drive centrifuge units. All major wear components are manufactured from abrasion-resistant materials, ensuring long service life even when handling fine, abrasive solids commonly generated during diamond core drilling. The robust mechanical and hydraulic structure also minimizes routine maintenance and supports continuous operation in harsh field conditions.

Supplying three independent centrifuge packages gives the drilling contractor greater operational flexibility. The units can be deployed individually or in parallel depending on project scale, drilling depth, or fluid volume, providing a scalable solution that adapts to different project requirements.

Through this project, GN Solids Control once again demonstrates its expertise in developing application-specific solids control solutions. By combining diesel-powered hydraulic systems with compact decanter centrifuges, GN delivers reliable, flexible, and field-proven equipment that supports efficient diamond core drilling operations worldwide.

GN Solids Control has recently supplied a set of High-G drying shakers and mud agitators to a Middle East customer, providing a practical and efficient solution for drilling fluid management and solids control. Rather than focusing on individual equipment alone, this project highlights how properly matched solids control and mixing equipment can significantly improve overall drilling system performance.

In modern drilling operations, especially in the Middle East, managing drilling fluids is not only about separating solids but also about maintaining fluid stability throughout the entire circulation process. High temperatures, abrasive cuttings, and long drilling cycles demand equipment that can operate continuously while delivering consistent results. GN’s solution addresses these challenges through a balanced combination of drying and mixing technologies.

The GN High-G Drying Shaker plays a critical role in the later stages of solids control. Positioned after primary shale shakers or mud cleaners, the drying shaker focuses on recovering residual drilling fluid from cuttings. By generating high vibration force, the shaker efficiently reduces liquid content in discharged solids, allowing operators to reclaim valuable drilling fluids and reduce the volume of waste requiring disposal. This contributes directly to lower operating costs and improved environmental performance.

Equally important is the role of the mud agitator in maintaining stable drilling fluid properties. Poor agitation can lead to solids settling, inconsistent mud density, and reduced separation efficiency downstream. GN mud agitators are designed to provide continuous and uniform mixing inside mud tanks, ensuring that solids remain suspended and additives are evenly distributed. This stable feed condition supports the performance of the entire solids control system, including the high-G drying shaker.

From an operational perspective, the integration of GN drying shakers and agitators helps reduce non-productive time. Cleaner fluids reduce wear on pumps and drilling tools, while consistent mixing minimizes the need for frequent adjustments or corrective actions. The result is a smoother drilling process with fewer interruptions and more predictable performance.

Durability and maintenance were also key considerations for this Middle East project. Both the drying shakers and agitators are built with heavy-duty structures, wear-resistant components, and corrosion-protected surfaces suitable for harsh environments. These design features extend service life and reduce maintenance frequency, which is especially valuable for remote or continuous drilling operations.

Another advantage of GN equipment is its compatibility with existing systems. The drying shakers and agitators were designed to integrate seamlessly with the customer’s current mud tanks and solids control layout, minimizing installation time and avoiding major system modifications. This flexibility allows operators to upgrade performance without significant downtime.

Through this project, GN Solids Control demonstrates its ability to deliver not just individual machines, but process-oriented solutions that improve drilling efficiency, reduce waste, and enhance long-term operational value. With extensive experience in Middle East oilfield projects, GN continues to support drilling companies with reliable equipment and practical engineering solutions tailored to real-world operating conditions.
