Produced Water Contamination Reduction, North Sea Oil Platform


Operator. UK Sector of the North Sea.


North Sea

About Our Client

Our client for this project is an Operator in the UK sector of the North Sea.

The Challenge

Our client was experiencing challenges with produced water contamination on a North Sea platform. Separo was approached to deliver a solution to reduce Oil in Water (OIW) content to meet the Operators internal targets and ensure environmental compliance.

The Operator was recording produced water contamination in excess of 1000ppm during startup, and in excess of 30ppm during normal operations. They were motivated to reduce the OIW levels to ensure environmental compliance and meet their own internal corporate standards.

Successfully reducing OIW levels would also avoid the risk of enforcement action from the environmental regulator, ensuring no impact to production.

What We Did

case study produced water solutionThrough close collaboration with our client, we were able to provide an effective solution capable of handling high levels of contamination and flowrates of up to 40 m3/hr. Following the presentation of our solution and subsequent HAZOP, our SepSORB® system was approved for installation. Separo supplied all hoses and fittings to tie into the receiving point and the discharge point, along with a pre-filter system and the SepSORB® filter vessels.

A Separo Filtration Specialist installed the equipment and provided training in its operation to the platform's core crew.

Value Gained

Separo’s SepSORB® systems are effective in reducing OIW content to levels below 5ppm in a single pass. SepSORB® has enabled the platform to treat produced water at source, meet environmental compliance and continue with production.

The system was inspected by the environmental regulator who provided positive feedback that the Operator was meeting their obligations, allowing them to progress within the terms of their licence.

Project Statistics

Separo’s produced water treatment at source solution has enabled the Operator to meet environmental compliance and reduce their carbon footprint.

Some additional benefits gained by our client are:

  • Plug-and-play system with no media handling, safer for platform personnel.
  • Water treated at source, reduced transport costs and emissions.
  • System can be scaled up to suit client requirements, OIW levels in excess of 1000ppm successfully treated.
  • Reduction in sampling required on platform.
  • Reduction in operational resources required to monitor OIW.
The primary aim of the skid install was to address our OIW issues and so far we are very impressed. The regulator was also very happy that we had it under control and internally the skid is getting positive attention.
