On Quantifying Global Carbon Emission From Oil Contaminated Lands Over Centuries, Kaveh Sookhak Lari, Greg B. Davis, Trevor Bastow, John L. Rayner

Research outputs 2022 to 2026

Petroleum releases into the subsurface contribute to global soil carbon emissions. Quantifying releases and changes in releases of carbon from soils over the lifetime of a spill is complex. Natural source zone depletion (NSZD) of light non-aqueous phase liquids (LNAPLs) embodies all key mechanisms for transformation to carbon gases and their release from soils including partitioning, transport and degradation of petroleum components. Quantification of the interconnected behaviours of the soil microbiome, fluid flow, multi-component transport, partitioning, and biodegradation is crucial for understanding NSZD. Volatilization from LNAPL, aerobic biodegradation, methanogenesis, and heat production all lead to release of greenhouse gases to …


Quantifying The Benefits Of In-Time And In-Place Responses To Remediate Acute Lnapl Release Incidents, Kaveh S. Lari, Andrew King, John L. Rayner, Greg B. Davis Jan 2021

Quantifying The Benefits Of In-Time And In-Place Responses To Remediate Acute Lnapl Release Incidents, Kaveh S. Lari, Andrew King, John L. Rayner, Greg B. Davis

Research outputs 2014 to 2021

Acute large volume spills from storage tanks of petroleum hydrocarbons as light non aqueous phase liquids (LNAPLs) can contaminate soil and groundwater and may have the potential to pose explosive and other risks. In consideration of an acute LNAPL release scenario, we explore the value of a rapid remediation response, and the value of installing remediation infrastructure in close proximity to the spill location, in effecting greater recovery of LNAPL mass from the subsurface. For the first time, a verified three-dimensional multi-phase numerical framework and supercomputing resources was applied to explore the significance of in-time and in-place remediation actions. A …
