We have an interest in the Bongkot field in the Gulf of Thailand. The Bongkot North processing platform was installed more than 15 years ago and, as such, has minimal produced water treatment facilities. However, robust procedural controls and a tight maintenance regime implemented on the produced water treatment and re-injection system have ensured that water is never disposed of overboard. The field produces some 23 000 barrels of water per day, all of which is re-injected into the reservoir after minimal treatment.
