Environment Report 2017

Associated gas is produced along with other hydrocarbons in parts of the UKCS, predominantly as a by-product of oil production. Where possible, associated gas is either used offshore for power generation or exported to nearby installations or to shore. Figure 16 compares the associated gas produced with the amount subsequently flared and vented. In some cases, small volumes of associated gas are flared or vented for operational or safety reasons. While the level of flaring increased in 2016, the percentage of associated gas flared continues to fall, having plateaued during 2013 and 2014. In 2016, 6 per cent of associated gas was flared. This highlights the improved methods and technologies operators are using on newer installations that minimise flaring where practicable.
