KOSUN Mud Cooling System: Ensuring Safety in High-Temperature Drilling
As global energy demand rises, oil and gas drilling operations are increasingly targeting complex environments such as deep wells, ultra-deep wells, and high-temperature high-pressure (HTHP) formations. In these extreme conditions, drilling fluid temperature control becomes a critical factor in maintaining both operational safety and efficiency.
The KOSUN Drilling Fluid Cooling System is engineered to meet this challenge, delivering reliable performance in the most demanding drilling environments—onshore or offshore.

Why Temperature Control Matters in HTHP Drilling
Drilling fluid plays a vital role in cooling the drill bit, transporting rock cuttings, and stabilizing the wellbore. However, when mud temperature exceeds optimal levels, it can lead to reduced viscosity and lubrication, thermal fatigue and damage to downhole tools, and accelerated degradation of chemical additives. Effective temperature management is essential for safe and efficient drilling.
Key Features of the KOSUN Mud Cooling System
With over 30 years of experience in solids control, KOSUN offers a modular and intelligent cooling solution tailored to site-specific needs.
Intelligent Temperature Control: The system automatically activates evaporative cooling when dry mode is insufficient. This extends the lifespan of drill bits and drill pipes while enhancing overall rig productivity.
High Energy Efficiency: The system cools drilling fluid by 20–40°C. Finned heat-exchange tubes improve thermal efficiency by 10%, reducing energy consumption and operating costs.
Rugged Adaptability: Suitable for land rigs, offshore platforms, and HTHP wells, the system is built with corrosion-resistant and high-temperature materials. It performs reliably in gas hydrate and geothermal operations.
Compact and Modular Design: The system delivers high processing capacity in a small footprint. Anti-freeze piping layout resists scaling, and the design is easy to install and maintain in confined rig spaces.
Applications of the KOSUN Mud Cooling System
The KOSUN mud cooling system is widely used in high-temperature formations such as geothermal wells and high-temperature oil and gas fields, deep and ultra-deep drilling projects, and high-density mud operations that retain more heat.
Proven Value for Drilling Operators
KOSUN mud cooling systems have been deployed in numerous deep well projects worldwide, delivering measurable results. Enhanced safety through fewer high-temperature-related failures, extended equipment life with consistent thermal protection, faster drilling by reducing non-productive time, and lower costs through smart controls and energy-saving design.
