Drilling waste management was established in the drilling industry in late 1980’s, which is driven by high exploration and production activities, ever increasing stringent government regulations and escalating investments from the oil and gas operators. The trend is set to continue further with the current surge in offshore activities and shale reserve exploratory activities.

Waste management technology is a critical constituent of successful drilling and production operations. The appropriate application of waste management principles is essential for both effective drilling operations and environmental protection. Waste streams from drilling, largely include drilling fluids and cuttings that are collected, processed, handled, transported, and disposed.
 

KOSUN, as the pioneer in the field of solids control in China as well as an integrated service supplier of global drilling fluids solids control and waste treatment, has established a reasonable waste management system after years’ efforts and experience in the field. The system is aimed at nipping the problem in the bud. The self-designed solids control equipment would efficiently reduce the amount of waste at its source at first.

During the operation, KOSUN's solids control system which is connected directly onto mud pump will process drilling fluids via four phases, effectively recover them as much as possible and minimize the waste disposal. Thus the drilling mud is well recovered and waste disposal minimized. Meantime, the full use of dewatering solution on further waste management not only effectively recovers water resources, but also reduces both the water content and volume of discharged waste and well protects the environment. Then treated drilling mud can be directly put into use and discharged waste will experience further solid/liquid separation being transported into Hi-G Dryer and Vertical Centrifuge by propeller after dewatering process. On the other hand, removed water may be recycled after being treated in drilling fluids purification system. And the waste residues may turn very dry after coming out of Hi-G Dryer and Vertical Centrifuge. When they are processed again by means of solidification, biodegradation, thermal desorption and cuttings re-injection. In this way, the zero waste disposal is realized.

The set-out solution will in the future act as a goal for which KOSUN people will pull every strength to achieving, thus forcing the pollution problems to give the way to green drilling.
