Decommissioning and Rehabilitation Project
Mitsui E&P Australia (MEPAU) is undertaking deconstruction and decommissioning activities throughout our Perth Basin permits as part of a campaign to rehabilitate sites which are no longer in use. Decommissioning is an established industry practice undertaken at the end of life of a well or facility using a decommissioning plan approved by the government regulator.
Well decommissioning involves environmentally sound and safe isolation of the well. Typical steps of the process include removing any production tubing, isolating productive formations from other formations by installing cement plugs at several intervals, pressure testing of the cement plugs, cutting off the well head below ground level, removing remaining surface equipment and facilities and rehabilitating the site to an agreed end use.
Deconstructing is the first phase of removing a redundant production facility site. It involves removing gas processing equipment and other infrastructure.
Typical steps of the process include removing surface equipment and facilities, concrete bunding and laydown pads then rehabilitating the site to an agreed end use. Where possible, equipment and materials are reused or repurposed.
Other than the the Woodada gas field site, most of the sites are on cleared agricultural land. MEPAU is using local services and supplies whenever practical.
Landowners and nearby residents are being consulted prior to activities starting at each site.
