GN CBM Drilling Mud System

GN Solid Control is proud to introduce the GNLW454GT Mud Dewatering Centrifuge, a key solution engineered for the efficient treatment of hydrovac slurry and directional drilling mud.

This robust decanter centrifuge is central to waste management systems designed for projects involving hydroexcavation and Horizontal Directional Drilling (HDD). The primary application is processing the soil, slurry, or “soup” generated during these operations. The goal is effective liquid and solids separation, which transforms the waste stream into reusable solid material for construction applications and clean water suitable for discharge.

The slurry treated typically originates from non-contaminated sources. These include physical utility work within public right-of-ways and directional drilling projects for the installation of underground pipes, utilities, and other private construction activities.

The GNLW454GT centrifuge is provided as a comprehensive, modular system to enhance operational efficiency. The module features a telescopic skid for secure and accessible mounting of the decanter centrifuge. It is also equipped with a catch tank for the collection of centrifuged discharge water and a centrifugal pump to facilitate easy water transfer for subsequent use or disposal.

This integrated solution underscores GN’s commitment to providing advanced equipment that helps industries manage their waste streams responsibly, promoting material reuse and environmental stewardship.

In the demanding field of drilling operations, the efficiency and reliability of solids control equipment are paramount. We are proud to announce the successful preparation and dispatch of a comprehensive set of high-performance solids control equipment designated for a powerful 2000HP drilling rig bound for Europe. This shipment underscores our commitment to supporting advanced drilling activities with robust and efficient solutions.

The carefully selected package for this European project includes some of the core components of a modern drilling fluid system:

3 Units of GNZS594K Shale Shakers: As the primary line of defense in solids control, these shale shakers are designed to remove large drill cuttings from the drilling fluid. The GNZS594K model is known for its high processing capacity and efficient screening performance, ensuring cleaner fluid for the subsequent stages.

1 Unit of GNZJ594K-3S16N Mud Cleaner: This unit combines the functions of a desander and a desilter, typically featuring a shale shaker atop a set of hydrocyclones. It provides secondary fine solids removal, significantly enhancing the quality of the drilling mud by eliminating smaller, abrasive particles that the primary shakers cannot capture.

1 Unit of GNZCQ360 Vacuum Degasser: Essential for maintaining mud density and preventing hazards, this vacuum degasser is tasked with removing unwanted gases (such as H₂S, CO₂, or methane) that may have infiltrated the drilling fluid. The GNZCQ360 model efficiently restores the fluid’s density and helps maintain wellbore stability.

1 Unit of GNLW363D Decanter Centrifuge: Acting in the tertiary stage, this decanter centrifuge is crucial for separating ultra-fine solids and recovering valuable barite from the drilling fluid. This process not only reduces overall solid content but also helps in controlling mud properties and reducing costs.

This specific configuration for the 2000HP rig highlights a complete and balanced approach to solids control and fluid management. Each piece of equipment plays a vital role in the process, working in tandem to ensure the drilling fluid is maintained at optimal properties throughout the operation. This leads to enhanced drilling efficiency, reduced equipment wear, better wellbore stability, and overall safer drilling practices.

Our extensive experience in supplying equipment for international projects ensures that all units are manufactured to meet stringent quality standards and are suitable for the rigorous demands of the European market. This shipment reinforces our capability to deliver reliable and effective solutions for high-power drilling rigs worldwide.

GN Solids Control once again made a significant impact at the prestigious ADIPEC 2025 exhibition, held in Abu Dhabi. Building on its established reputation, the company showcased its latest advancements in solids control and separation technology, presenting innovative solutions designed to enhance efficiency and promote more environmentally responsible practices in the oil and gas industry.

Visitors to the GN booth had the opportunity to engage with technical experts and explore the sophisticated engineering behind the showcased equipment. The display highlighted how these systems are engineered not only for superior performance and reliability but also for optimizing resource usage. This leads to significant reductions in waste volumes, lower consumption of fresh water and chemicals, and a more manageable waste stream, all of which align with the industry’s growing focus on sustainability and operational excellence.

A key takeaway from the event was GN’s dedication to providing comprehensive solutions that address both operational and environmental challenges. The technology on display underscored a clear message: achieving high efficiency and embracing eco-friendly practices are not mutually exclusive. Through intelligent separation, the industry can improve its bottom line while simultaneously demonstrating a stronger commitment to environmental stewardship.

GN’s successful participation at ADIPEC 2025 reinforces its position as a forward-thinking leader in solids control. The company continues to drive progress by developing technologies that help the oil and gas sector operate more cleanly and efficiently, paving the way for a more sustainable future in energy development.
