Drilling waste treatment: Reducing costs and increasing efficiency, creating a New Era of green drilling!
Jul 31, 2025
Amid the roar of oilfield development, drilling operations are advancing efficiently. However, the drilling waste that comes along with it has become a persistent problem plaguing the industry's development - the traditional disposal methods are costly, environmental protection pressure follows closely, and the waste of resources is truly regrettable. How to break the deadlock? The drilling waste treatment technology developed by Xi 'an KOSUN offers you a one-stop green solution!
The first step: Reuse and "cut off the flow" from the source
In traditional drilling, the landing of mud is the "starting point" of pollution - mud mixed with heavy metals and petroleum substances seeps into the soil and is difficult to degrade naturally for 30 years.
The solid control equipment combined with the mud non-landing technology enables the mud to circulate in a "closed loop" within the drilling system.

Step 2: Reduction treatment + recycling, turning "waste" into "treasure"
During the drilling process, barite (a key raw material for drilling mud) is quite expensive. If it is lost along with the waste, it is equivalent to "pouring money into the mud".
The barite recovery technology of this system can efficiently extract barite from waste and reuse it for slurry preparation.

Step 3: Emission safety net, Zero risk for Compliance
Even after multiple layers of recycling, there is still a small amount of waste that needs to be discharged. The solidification,
biodegradation and thermal desorption technologies in the system make the emissions "harmless".

The working principle of the drilling waste treatment system is based on the comprehensive application of various technical means such as physical, chemical and biological methods. The uniformity of materials is improved through pretreatment. The effective separation of oil, water and residue is achieved by using solid-liquid separation technology. Then, through the oil recovery and wastewater treatment system, the recycling of oil and the standard treatment of wastewater are respectively realized. The waste residue is treated harmlessly to ensure the environmental friendliness of the entire treatment process.
From drill cuttings recovery, solid-liquid separation to drying and volume reduction, and resource reuse, the processing system is modularly designed and flexibly combined to adapt to various working conditions and processing requirements. It can be applied to onshore drilling platforms and shale gas Wells. Offshore drilling platform Projects such as co-processing of waste from petrochemical enterprises. The application of the drilling waste treatment system has effectively reduced environmental pollution during the oilfield development process and improved the utilization efficiency of resources. The drilling waste treatment system, as an important environmental protection equipment in the field of petroleum exploration and development, its research and application are of great significance for promoting the sustainable development of the petroleum industry. In the future, with the continuous advancement of technology and increasingly strict environmental protection requirements, this field will embrace an even broader development prospect.
