GN Solids Control has successfully commissioned a fully integrated 1000HP Drilling Rig Mud Tank System for a prominent oilfield operator in Yunnan Province, China. This deployment reinforces GN’s reputation as a trusted partner for turnkey drilling fluids systems that offer not only robust performance but also seamless field operation.

In today’s challenging drilling environments, reliability and integration are key. GN’s engineered system meets this need with a comprehensive setup designed to improve solids control efficiency, reduce non-productive time, and enhance HSE compliance.

Fully Integrated Mud Tank System
The system is composed of four functional mud tanks, each tailored for distinct purposes such as active mud circulation, mixing, and storage. Together, they form the operational backbone of the rig site’s fluid management strategy.

Core Equipment Supplied:
3 × GNZS594K Shale Shakers
Equipped with GN’s patented screen technology and robust dual-motor drive, these shakers provide high G-force linear motion to quickly separate large solids from drilling fluids. Their efficiency is critical to preventing formation damage and reducing wear on downstream equipment.
GNZCQ270 Vacuum Degasser
Removing entrained gases from the mud, this unit safeguards against gas-cut drilling fluid that could destabilize well conditions.
GNZJ752K-2S Desander & GNZJ752K-12N Desilter
This dual-stage hydrocyclone solution offers precise separation of sand and silt-sized particles. The integration with mini shakers underneath ensures dried discharge and continuous operation.
GNLW452D Decanter Centrifuge
Positioned as the final stage of solids removal, this medium-speed centrifuge efficiently handles low-gravity solids and recovers barite, keeping mud weight and rheology in optimal condition.
Auxiliary Equipment
The system also includes mud agitators, centrifugal sand pumps, a mud mixing funnel, and an explosion-proof electrical control system, ensuring safe and efficient fluid recirculation and mixing.

Field-Proven, Operator-Trusted
