In today’s drilling industry, efficiency, safety, and cost control depend heavily on the quality of drilling fluids. Contaminated fluids filled with ultra-fine solids can lead to equipment damage, increased downtime, and higher mud costs. To address these challenges, the Desilter in solids control systems plays an essential role. Positioned downstream of the shale shaker and desander, the desilter ensures the removal of ultra-fine solids measuring 15–45 microns, which keeps drilling mud cleaner and more reusable.

At Petropath Fluids India Limited, we specialize in designing and manufacturing high-performance API-compliant Desilters for both onshore and offshore operations. Our solutions are engineered to international standards, helping drilling contractors and operators achieve optimal fluid performance, reduce environmental impact, and maximize the longevity of their equipment.
Desilter in Solids Control Systems
During drilling, the wellbore produces cuttings and other debris that contaminate drilling mud. While shale shakers and desanders handle larger particles, they cannot manage ultra-fine solids effectively. This is where a desilter becomes critical.
By using an advanced oilfield desilter equipment system, operators ensure that drilling mud remains within specifications. Cleaner mud enhances drilling efficiency, protects mud pumps and bits, and reduces the likelihood of non-productive time (NPT).
The presence of a desilter for oil and gas rigs ensures consistency, especially in complex wells such as CBM, geothermal, and deep offshore projects.

Our desilters are built with precision engineering and reliable materials to withstand demanding drilling conditions.

Top 5 Benefits of Using a Desilter

Investing in a Desilter in solids control systems provides multiple operational and financial benefits:

  • Improved Mud Quality – Removes harmful fine particles for better drilling fluid performance.

  • Extended Equipment Life – Protects pumps, bits, and motors from abrasive wear.

  • 💧 Lower Mud Costs – Enhances fluid recycling and reduces the need for new mud.

  • 🛠️ Operational Efficiency – Prevents downtime by keeping mud within drilling specifications.

  • 🌍 Environmentally Responsible – Minimizes waste volumes and supports sustainable drilling.

The desilter for oil and gas rigs is used across multiple drilling setups:

  • Onshore and offshore rigs for fine solids removal.

  • Integrated into drilling fluids solids control systems for better performance.

  • Coal Bed Methane and geothermal wells for unconventional drilling operations.

  • Mud recycling units where efficient solids removal enhances fluid circulation.
