KOSUN's WBM Drilling Waste Management System Gains Recognition from Russian Clients

Dec 25, 2025

In the modern oil and gas exploration and development sector, increasingly stringent environmental regulations have made the reduction and resource-oriented treatment of drilling waste a key indicator of a contractor's core competitiveness. As an integrated solution for eliminating wellsite pollution and achieving "green drilling," the Water-Based Mud (WBM) Drilling Waste Management System has become a vital component of global drilling technology.
 
I. Core Process Logic of the WBM Drilling Waste Management System
 
The WBM drilling waste disposal system is an engineering framework that achieves solid-liquid separation through physical and mechanical means. Its primary objective is to efficiently extract the liquid phase from waste drilling fluids and reduce the moisture content of solids, ensuring that cuttings meet disposal standards.
 
Collection and Conveyance: After the primary shale shaker removes large solid particles, the waste mud and cuttings are transported to the system via screw conveyors.
Solid-Liquid Separation: Materials undergo initial separation through a drying shaker (utilizing vibration and screen filtration) to remove liquids from the cuttings.
Chemical Treatment: Chemical agents are added and stirred in flocculation tanks to enhance subsequent separation efficiency.
Deep Dewatering via Filter Press: The destabilized mud enters a filter press for mechanical pressure dewatering, forming "mud cakes" with extremely low moisture content.
Recycling and Reuse: Treated liquids (effluent or reusable mud) are returned to recycling tanks for reuse; dried cuttings are utilized for wellsite reinforcement or roadbed construction.

 
II. KOSUN’s Water Based Drilling Fluid Treatment System Highly Praised by Russian Clients
 
On December 23, 2025, a delegation of energy industry experts from Russia was invited to visit a KOSUN drilling sludge dewatering system project site at the Chuanqing Oilfield in Chongqing, China. The focus of the inspection was to evaluate the system’s stability in treating water-based mud under complex geological conditions and the final moisture content of the solids.
During the visit, the clients closely observed the solid discharge at the end of the process. Cuttings treated by KOSUN’s system demonstrated high stability in dryness and form, completely eliminating the "semi-fluid" state.
The Russian client remarked: "The treatment results demonstrated by KOSUN’s system perfectly meet our technical expectations for an 'ideal solid state.' It is truly impressive."
   
III. Economic and Environmental Value of the WBM Drilling Waste Management System
 
Environmental Compliance: Through a closed-loop circulation mode, the system achieves "zero discharge" of cuttings and prevents mud spillage, effectively mitigating environmental regulatory risks for operators.
Significant Reduction in Operating Costs: Efficient liquid phase recovery substantially reduces the cost of preparing new mud; meanwhile, the volume of treated solids is greatly reduced, significantly lowering downstream transportation and final disposal costs.
Optimized Wellsite Safety and Footprint: The pitless-management approach minimizes the equipment footprint, fostering a cleaner operation site in compliance with international standards for modern "green" drilling sites.
 
As a leading global supplier in Drilling Waste Management, KOSUN remains committed to addressing the most rigorous environmental challenges through technological innovation. The international recognition received at the Chongqing project site once again validates the international standards of its WBM Drilling Waste Disposal System in terms of process reliability and treatment performance.
In the face of increasingly complex resource development environments, KOSUN will continue to provide customized cuttings management solutions to help global oil and gas companies achieve synergy between environmental benefits and economic returns.
