Contaminated Soil and Oil-Based Mud Cutting Treatment Systems

GN Solids Control is a leading name in the design and manufacturing of oil – based mud (OBM) cutting treatment systems. GN can send our engineers for the first – time installation and commissioning to ensure a smooth start – up for our clients.​

Key Separation Equipment​
Vertical Cuttings Dryer​
The vertical cuttings dryer is the star of our OBM cuttings treatment lineup. It is the primary separation equipment for OBM cuttings treatment and is highly efficient. With this advanced technology, it can reduce the Oil on Cuttings (OOC) to an impressively low range of 3 – 5%. This significant reduction not only helps in waste management but also has cost – saving implications for the oil and gas industry.​
High G Drying Shaker​
While the high G drying shaker is mainly designed for water – base mud cuttings, some clients have also used it for OBM cuttings. However, it has its limitations. It can only reduce the OOC to around 10%. This makes it clear that for optimal OBM cuttings treatment, the vertical cuttings dryer is the better choice.​


High – Speed Centrifuge​
High – speed centrifuge plays a crucial role in the treatment process. It is used after the vertical cuttings dryer. Its function is to reduce the mud weight and make the mud qualified for reuse. By recycling the mud, we not only save resources but also contribute to a more sustainable drilling operation.​
Treatment Locations​
It understand that every client has different operational setups. Some may choose to treat the cuttings at the rig site, while others prefer to collect the cuttings and treat them in their yards. To better serve clients, GN Solids Control will send a question list on waste management in investigate the project information and demands. This will enable GN to offer clients more tailored and proper solutions.​

GN Solids Control Solutions​
Solution 1: Vertical Cuttings Dryer and High – Speed Centrifuge Package​
This package is an excellent choice for treating fresh OBM cuttings at the rig site. It is relatively easy to implement and highly effective. With this solution, our system can reduce the OOC to the 3 – 5% range, ensuring efficient waste reduction right at the source.​


Solution 2: Oily Sludge Separation System for Old Oily Sludge in Waste Pits​
For the old oily sludge in waste pits, we offer the oily sludge separation system. We have a successful project reference in Qatar that showcases the effectiveness of this solution.
In this project, the results were remarkable:​
Oil on Solids: 1 – 3%​
Water in Oil: 3 – 5% (BS&W)​
Oil in Water: 1%​

GN Solids Control OBM cuttings system is a waste – reducing system that can be used before TDU (Thermal Desorption Unit) to improve TDU efficiency.

GN Containerized Sludge Dewatering Package for Soil Remediation in Middle East

GN Solids Control recently developed a Containerized Sludge Dewatering System for a Middle East project, designed specifically for contaminated soil treatment and cleaning. This innovative system is fully integrated into a 40-foot fabricated container, ensuring easy transportation and quick on-site installation. All components are pre-assembled and connected in the container, minimizing the time and effort required for installation at the project site.

The system includes the following key equipment:

High-Speed Big Bowl Decanter Centrifuge (GNLW654-VFD): This centrifuge is designed for efficient dewatering of sludge. It is equipped with a Variable Frequency Drive (VFD), allowing precise control of the centrifuge’s speed to optimize solids separation and ensure high performance in the dewatering process.

Feeding Pump (GNG30-075C): The system uses a 7.5kW screw pump, which is typically used to feed a 14-inch centrifuge. However, since the dewatering treatment capacity is much smaller compared to mud treatment, this smaller pump is a more suitable fit for the system, providing the necessary flow rate for the sludge dewatering process.

Polymer Dosing Pump (GNG05-030C): A screw pump is used as the polymer dosing pump. This pump is responsible for adding the appropriate amount of polymer to the sludge, which aids in the coagulation and flocculation processes, allowing for more efficient solid-liquid separation during dewatering.

Slag Screw Conveyor (GNSC10B-7.5M): A screw conveyor is used to transfer the separated sludge (slag) from the centrifuge to the designated disposal or storage area, ensuring continuous operation without manual intervention.

The entire system is housed in a 40-foot container, which provides a compact and mobile solution for on-site sludge dewatering. The containerized design ensures that the equipment is easily transportable, and the pre-connected system significantly reduces installation time at the project site. This approach provides a turnkey solution for contaminated soil treatment and cleaning, offering a streamlined process and efficient operation.

This containerized sludge dewatering system from GN Solids Control is an ideal solution for projects requiring reliable, high-performance dewatering equipment in a compact and easily deployable format.
