GlobalData expects that an average capex of $7.5bn per year will be spent on 454 oil and gas fields in Australia between 2018 and 2020. Capital expenditure on Australia’s oil projects will add up to $3.8bn over the three-year period, while investments into gas projects in Australia are anticipated to total $18.7bn in upstream capital expenditure by 2020.

Deepwater projects will be responsible for over 48% of $22.5bn of upstream capital expenditure in Australia, or $10.7bn by 2020. Shallow-water projects will account for 37% of upstream capital expenditure with $8.4bn by 2020, while onshore projects will take $3.4bn in capital expenditure over the period.

GlobalData forecasts that Royal Dutch Shell Plc will lead Australia in capital expenditure, investing $3.6bn into the country’s upstream projects by 2020. Chevron Corporation and Inpex Corporation will follow with $3.2bn and $2.7bn investment, respectively, into Australia’s projects between 2018 and 2020.
