4.3 Production Chemicals In 2017, the amount of production chemicals discharged per operator ranged from 0 to nearly 4,500 tonnes. This does not directly correlate to production levels as differing hydrocarbon properties and process conditions dictate the amount of chemicals used. The mean amount of chemicals discharged to sea per operator decreased in 2017, to 852 tonnes, from 885 tonnes in 2016.

A total of 2,625 tonnes of oil equivalent were produced per tonne of production chemical discharged to sea in 2017, a decrease on the 3,095 tonnes of oil equivalent in 2016.
