Changing environmental regulations are increasing pressure on the oil and gas industry to both demonstrate and report on contributions made to positive environmental outcomes. One way to capture these contributions can be achieved through the circular economy during the closure of site.
An effective closure strategy that produces maximum recycling yield and minimum landfill can provide opportunities to oil and gas companies for more effective reporting while increasing transparency.
In 2021, it was estimated that there were approximately 5,695 kilotons of decommissioning material that would require disposal in Australia. Most of the disposal mass comes from removal of the pipeline infrastructure, dominated by steel and concrete, gas export trunklines and intra-field pipelines.
While capturing waste for scrap metal contributes significantly to recycling volumes, other materials can be more challenging to separate and process and thus threaten recycling targets. Contaminants commonly found in oil and gas assets of particular concern include NORMS, mercury, fuel oils, asbestos and caustic materials. Safely managing these contaminants requires more intensive processes, skilled personnel and the most stringent safety protocols to minimise risk.
