Integrated Produced Water Re-Injection Management

Integrated Produced Water Re-Injection Management

The injection of water into reservoirs can result in a number of serious problems. One reason for questioning existing water treatment systems is to combat complexity. Water handling systems are becoming too complicated. Many prejudices and misconceptions have arisen that simple solutions found in normal operating techniques are being lost in the mire of complication. The impact of chemicals in this process and their pros and cons will be highlighted.

This course will cover the produced water handling, treatment and re-injection. The aim is a modern, clear understanding (including guidelines) of water quality definition, measurements and its impact on the injection well behaviour in the long term. Regarding the water quality for injection one can say: You can’t optimise what you don’t measure.

How we build your confidence

The course focuses on practical onsite experience. Case histories and practical examples will be subdivided into the following sections: Required quality for re-injection, separator improvements, field experience, efficiency of modern water treatment units. Lectures are supported with video clips.Register now

Suitability - Who should attend?

  • A production or facility engineer, project manager, production chemist, a member of field operational staff currently or potentially involved in water treatment in production operations
