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.

3000HP Drilling Rig Solids Control System for Asia Drilling Company

A 3000HP drilling rig requires high standards for drilling mud solids control equipment due to its larger scale and more demanding operational needs. GN Solids Control designs the mud system to accommodate larger volumes of drilling fluids and ensure efficient solids control throughout the drilling process.

The mud system includes an 80bbl trip tank, complete with a centrifugal trip pump. The trip tank features a level meter with a 0.5bbl level indicator, ensuring precise monitoring of the mud volume. There are three active mud tanks in the system: a shale shaker tank, an intermediate tank, and a suction tank, each with a 500bbl capacity. These tanks are essential for maintaining the right balance of drilling fluids during operations.

In addition, the system includes four reserve tanks for mud storage, with a total capacity of 2000bbl. The setup also includes three water tanks and a 70bbl pill tank to support various operations and drilling fluid maintenance.

A comprehensive mixing system is integrated into the mud system for deep drilling rigs. The mixing system consists of two mixing hoppers, three centrifugal mixing pumps, and one shearing pump for use and backup. This setup ensures that drilling fluid is mixed effectively to maintain consistent viscosity and performance.

To handle the high flow rates and large volumes of drilling fluid, the system uses three sets of GNZS596K double-deck shale shakers. These shakers are specifically designed for large-capacity applications and utilize the same size replacement screens for both the upper and bottom decks, ensuring ease of maintenance and consistent performance.

After the shale shakers, the system includes a 1500GPM mud gas separator, a vacuum degasser, and a mud cleaner to further treat the mud and remove gases, solids, and contaminants. 100hp centrifugal pumps are used to feed the desander and desilter units, ensuring proper flow rates and efficient separation of fine solids.

The system is also equipped with necessary mud agitators and mud guns to keep the mud in suspension and maintain optimal fluid properties during the drilling process.

This comprehensive mud system ensures that the 3000HP drilling rig operates efficiently, with advanced equipment for solids control, fluid management, and waste disposal.
