The petroleum industry is broadly split into upstream and downstream petroleum sectors. The upstream sector refers to exploration and production of crude oil while downstream refers to refining of crude oil and the distribution and sale of petroleum products.
In 2011, total throughput at petroleum terminals was 1,388 ML. The DEC of petroleum terminals was $19 million.
The Audit projects an increase in throughput of 2,355 ML per year by 2031 - an increase of 2.7 per cent per year. This is projected to result in a growth in DEC of $13 million (70 per cent) to $32 million.
