Shell’s Australian unit plans to develop its next wave of onshore natural gas fields in Queensland to supply gas to domestic and LNG export customers for the next 30 years.

During 2019 and 2020, Shell will progressively drill 250 new gas wells as part of the QGC venture in the Western Downs region of Queensland, the company said in a statement.

The wells will connect to existing QGC gas processing plants and will bring approximately 930 petajoules of gas to market over the next three decades.

Shell Australia chairman Zoe Yujnovich said the project will bring more gas both to Shell’s Australian and LNG export customers.

In the first half of 2018, Shell has already spent $140 million in Toowoomba and Surat Basin communities on goods and services supporting its existing operations.

The company currently supplies around 60 percent of Queensland’s domestic gas demand through both QGC and Arrow Energy.
