Under the contract, CPB Contractors will be responsible for delivering over 300 coal seam gas wells over two years.

The scope of contract includes infrastructure for access tracks and well site lease pad preparation, electrical supply networks, gas and water pipeline gathering networks, and rehabilitation of right of ways after the completion of installations.

The company said that the contract strengthens its position as a key delivery partner in the provision of gas infrastructure in the Australian state.

Over the last five years, the CIMIC Group company has provided gas gathering infrastructure for over 800 wells for APLNG, which is a joint venture between Origin (37.5%), ConocoPhillips (37.5%) and Sinopec (25%).

APLNG is the owner of the Australia Pacific LNG project, which includes the development of the company’s substantial coal seam gas resources located in the Surat and Bowen Basins, a 530km transmission pipeline, and a multi-train LNG facility on Curtis Island, near Gladstone.

CPB Contractors managing director Juan Santamaria said: “CPB Contractors is proud not only of our ongoing work in in this sector, but also our long-term opportunity to support and be part of communities in the Surat Basin.

“Our work with local subcontractors and suppliers continues to make important contributions to employment, business opportunities and community benefits for the people of Roma, Miles, Chinchilla and Dalby.”

Last month, CIMIC Group’s another subsidiary UGL secured contract extensions worth A$200m ($143.7m) for delivering maintenance and turnaround services for the Gorgon and Wheatstone facilities, and other projects in Australia.

CIMIC Group CEO Michael Wright said: “CIMIC Group has a long track record in the delivery of essential infrastructure and services for communities across Australia.

“CPB Contractors’ expertise in supporting the delivery of liquefied natural gas, combined with the specialist skills of Thiess, Sedgman and UGL, means the CIMIC Group continues to play a central role in the vital work of the energy and resources sectors.”
