Crescent Engineering delivers robust and reliable water treatment systems to support upstream oil and gas production — both onshore and offshore. Our modular and scalable solutions are engineered to handle the complex and variable nature of produced water, injection water, and seawater, ensuring consistent performance in harsh operating environments.

​

Key Capabilities:

• Produced Water Treatment:
  Efficient removal of oil, suspended solids, and fine particulates from produced water to meet regulatory discharge limits or prepare for reinjection. Our systems combine mechanical separation technologies with polishing stages to optimise performance and uptime.

• Injection Water Treatment & Seawater Filtration:
  Removal of particulates and biological contaminants from seawater or recycled water to ensure reservoir protection and effective injection. We support primary filtration, deaeration, and sulphate removal as required.

• Space-Efficient, Skid-Mounted Systems:
  Pre-engineered, compact treatment units designed for rapid deployment and easy integration with existing infrastructure. Ideal for offshore platforms, modular oilfield development, and fast-track projects.

Featured Technology: DualSPIN™ Deoiler Hydrocyclone

The DualSPIN™ deoiler hydrocyclone represents a major advance in compact produced water treatment. Designed as a direct drop-in replacement for conventional liners, it delivers enhanced oil-water separation without increasing system footprint or maintenance complexity.

Midstream

Crescent Engineering provides water treatment and process solutions that support the reliability and sustainability of midstream operations. Our technologies are engineered to manage water quality across pipeline networks, compression facilities, and separation plants — ensuring operational uptime and environmental compliance.

Key Capabilities:

• Process Water Treatment and Recycling
  Treatment systems that recover and recycle water used in cleaning, cooling, and operational processes. These systems reduce freshwater intake and minimise waste discharge, supporting more sustainable operations.

• Filtration and Solids Control in Pipeline Operations
  Advanced filtration solutions designed to remove particulates, hydrocarbons, and other contaminants from pipeline fluids. Our systems help prevent fouling, protect downstream equipment, and maintain flow assurance.

• Water Reuse in Compression and Separation Systems
  Closed-loop water recovery systems that support efficient cooling and separation processes. These systems help operators reduce water consumption and manage effluent quality within regulatory limits.
