Typical waste streams from drilling operations includes cuttings, slop and contaminated water. SAR has treatment facilities and technologies to handle all types of drilling waste.
SAR currently utilizes two technologies for treatment of drill cuttings TCC and ITDU. Both technologies are based on a thermal desorption process.
The TCC® (Thermo Mechanical Cutting Cleaner) is one of the most applied thermal desorption techniques utilized to treat drill cuttings. This technology converts kinetic energy to thermal energy in a thermal desorption process that efficiently separates and recovers the components of drilling waste whilst preserving the original quality of the components.
As a result, the recovered base oil can be returned to customer and re-used in new Oil Based Mud (OBM) or as fuel for diesel engines, whilst the cleaned solids have various industrial uses. The recovered water is sent to final biological treatment at our Mongstad plant.
The ITDU® (Induction Thermal Desorption Unit) is designed to treat oil contaminated soil and sludge such as drill cuttings and slop.
The ITDU® employs induction heat to increase the temperature in the waste to above boiling point for water and oil. The oil and water are condensed and cleaned; the characteristic of the oil is not altered in the process and the recovered oil is recycled for various use.
The recovered water is sent to biological treatment at our Mongstad plant (link). The technique has proven to be very energy efficient. The properties of the treated waste complies with the highest environmental standards.
SAR offers an environmentally friendly and cost-effective solution for treatment of oil-based slop and mud.
The WOSS (Water Oil Solids Separation) separates drilling slop and mud into water, oil and solids using decantation and separation technology.
The remaining sludge after WOSS treatment is further treated in the TCC to improve the quality on the recovered oil and minimize oil in solids.
The recovered oil from the WOSS process is recycled for various use. The recovered water is sent to biological treatment at our plant at Mongstad.
