Oil & Gas

Specialising in construction and engineering associated with supporting Coal Seam Gas (CSG) and Liquified Natural Gas (LNG) Projects, Decmil work with oil & gas industry clients to construct wellsites, downstream processing components, gas compressors and gas plants, non-process infrastructure such as control rooms, substations and workshops, and accommodation facilities.

Within Queensland’s booming CSG industry, Decmil continues to provide leading wellhead installation services and surface facilities to the Upstream Gas Gathering network for QGC.

Our experienced CSG personnel have an innate understanding of the unique challenges associated with CSG projects, backed by a history of lessons learnt and proven project management systems and processes.

Our experience in CSG encompasses:
• Fabrication, installation and construction
• Gas pipelines and plant
• Processing and compression facilities
• Upstream CSG surface infrastructure
