GN Solids Control is pleased to announce the successful shipment of a comprehensive solids control equipment package for a deep well drilling project in Pakistan. This customized solution includes three GNZS595 Shale Shakers, one GNZJ594K-3S16N Mud Cleaner, and two GNLW363D-FHD Hydraulic Drive Decanter Centrifuges, specifically engineered to address the unique challenges of deep well operations.

Solving the Challenges of Deep Well Drilling

How the GN System Delivers Value:

1. High-Efficiency Primary Removal: GNZS595 Shale Shakers
The three GNZS595 linear motion shale shakers serve as the first line of defense. Engineered with a large screening area and high G-force, they are capable of handling massive volumes of returning drilling fluid. This effectively removes large drill cuttings early, protecting downstream equipment from severe abrasion and reducing the overall solids load.

2. Precision Secondary Cleaning: GNZJ594K-3S16N Mud Cleaner
The mud cleaner combines desanding and desilting hydrocyclones over a fine-mesh shaker. This stage significantly reduces the medium and fine solid content in the mud. By maintaining the correct sand content and mud weight, it protects the downstream centrifuges from overload and ensures the drilling fluid is ready for the final fine-separation stage.

3. The Core Solution for Harsh Conditions: GNLW363D-FHD Hydraulic Centrifuges
The highlight of this package is the two GNLW363D-FHD hydraulic drive decanter centrifuges. In this system, an electric motor drives the hydraulic power unit, which then powers the centrifuge bowl and scroll via hydraulic motors. This design provides distinct advantages for deep well drilling:

Superior Load Adaptability & Overload Protection: Unlike traditional VFD electric drives that may frequently trip under sudden heavy loads, the hydraulic system provides exceptional torque and outstanding shock-load resistance. It easily handles high-viscosity mud and fluctuating solids discharge without interruption, minimizing non-productive time (NPT).

Precise & Flexible Speed Control: Operators can independently and continuously adjust the bowl speed and differential speed to optimize the separation of ultra-fine solids and recover valuable barite, keeping the mud density strictly within the required window for deep well safety.

Enhanced Reliability in Harsh Environments: By replacing complex electrical drive components with a robust hydraulic transmission system, the centrifuge is less susceptible to high temperatures and electrical failures, ensuring stable operation in the demanding Pakistani drilling environment.

Maximizing Overall Value

By integrating these three stages, GN provides the Pakistan client with a robust closed-loop system. It effectively controls the solids content, stabilizes mud properties, recovers valuable drilling fluids, and drastically reduces waste disposal volumes. Ultimately, the integration of the hydraulic drive technology ensures that the critical separation process continues smoothly, lowering the total cost of ownership for the client.

This delivery to Pakistan further demonstrates GN Solids Control's expertise in providing application-specific solutions for extreme drilling environments.
