Produced water treatment for mature offshore gas fields

Produced water treatment for mature offshore gas fields

Publieke samenvatting

During the late-life operation of natural gas fields it becomes more difficult to meet the specification for discharging produced water. As a result, TNO has jointly initiated a programme with ISPT under the TKI-Gas to identify alternative technologies to address this issue.

Several technologies are being evaluated in 2013 to address this issue. As a follow-up, further development work of the selected technology is proposed for 2014, in preparation for a pilot test - preferably onshore - in line with the original proposal. The current proposal covers development work/support for 2014, but excludes the actual pilot test.

Water treatment solutions for the development of unconventional gas were explicitly excluded from the proposal. This is the subject of a parallel TKI Gas proposal, and could be a subject for further research in a joint TNO/ISPT proposal for 2015.
