Oil-Based Drill Cuttings Treatment
During drilling operations, oil-based mud is separated from drill cuttings through a combination of mechanical conveying, centrifugal separation and fluid recovery processes.
The treatment system is designed to:
- Continuously receive and transfer drill cuttings from the drilling operation
- Separate recoverable drilling fluid from drill cuttings
- Reduce residual oil-based drilling fluid on treated cuttings
- Recover drilling fluids for potential reuse
- Reduce the volume of solids requiring transportation and final disposal
- Support cleaner and more efficient drilling waste management at the rig site
Key Equipment

The system can integrate the following equipment:
Vertical Cuttings Dryer
Uses high-speed centrifugal separation to remove drilling fluid from drill cuttings and improve liquid recovery.
High-Speed Decanter Centrifuge
Provides further solid-liquid separation of recovered drilling fluid and helps remove fine solids.
Screw Conveyor
Provides continuous and controlled transfer of drill cuttings between different treatment stages.
Skid-Mounted Tank
Provides process fluid collection and temporary storage within the integrated treatment system.
Slurry Pump and Agitator
Support stable fluid transfer and maintain solids suspension during treatment.
Cuttings Collection Container
Collects treated drill cuttings for subsequent transportation or disposal.
Treatment Process
The typical treatment process consists of:

The specific equipment configuration and process flow can be customized according to drilling fluid properties, cuttings characteristics, required capacity and site conditions.
Key Benefits
Efficient Continuous Treatment
Designed for continuous feeding and treatment to support uninterrupted drilling operations.
Improved Drilling Fluid Recovery
Separates recoverable drilling fluids from drill cuttings, helping reduce fluid losses and operating costs.
Reduced Residual Oil on Cuttings
The combination of centrifugal separation technologies helps reduce the amount of residual drilling fluid remaining on treated cuttings.
Reduced Waste Volume
Separating recoverable fluids from solids can reduce the volume of waste requiring transportation and final disposal.
Modular Skid-Mounted Design
The modular configuration facilitates transportation, installation and relocation between drilling sites.
Integrated PLC Control
Centralized control of major system components improves operational efficiency, monitoring and system safety.
Applications
The Oil-Based Mud Drilling Waste Management System can be applied to drilling operations where oil-based mud and drill cuttings require controlled on-site treatment, including:
- Oil and gas drilling
- Shale gas drilling
- Onshore drilling operations
- Offshore drilling operations
- Coalbed methane drilling
- Geothermal drilling
- Mining and exploration drilling
- Drilling operations in environmentally sensitive areas
KOSUN can configure the treatment system according to the drilling method, mud properties, cuttings characteristics, processing capacity and site requirements.
Field Application
KOSUN oil-based drill cuttings treatment systems have been applied in international drilling waste management projects, including projects in Algeria.
The system configuration can be adapted to different drilling conditions and environmental requirements to support efficient on-site treatment and responsible disposal of drilling waste.
