Brine Injection Facilities for Gladstone LNG project

Project Highlights:

• Reduction of 23% in total cost of ownership to Santos
• Engineering and equipment supply under one roof with reduced interface and thus saving in time.
• Detailed Engineering in Australia to ensure compliance with AS standards
• Majority of Drafting in India but engineering checks carried out in Australia
• Software Development in India under supervision of Australian team.
• Major savings in Software development costs.
• Sourcing of Electronic components including PLCs from European and American manufacturers approved by Santos
• Modular design panel to be installed within a self-contained transportable container
• System is designed for a remote unmanned site location
• Assembly of panels in India
• FAT offered in Perth, Australia prior to despatch to site   

Project Description:

The Roma coal seam gas field supplies gas to Gladstone LNG project in Queensland, Australia. Coal seam wells at Emu Park are located at remote location and associated water with Coal Seam Methane needs to be treated through reverse osmosis and reinjected in the ground.

The Brine Injection Project involved development of appraisal injection facilities which may be replicated over a number of wells in the Roma area for long term brine injection.

Access Petrotec has been awarded the design and development of unmanned Process Control System which could be remotely controlled through satellite link.
