METHANE EMISSIONS QUANTIFICATION AND CHARACTERIZATION 

We study greenhouse gas emissions inventories in the US, Canada, and abroad, with a focus on methane emissions through measurements, modeling, and data analysis.  We also analyze methane emissions reduction opportunities and strategies. Sectors of interest include petroleum and natural gas systems and urban sources.  

NON-PRODUCING AND ORPHANED OIL AND GAS WELLS

Non-producing oil and gas wells can acts as pathways for fluid migration into groundwater aquifers and gas emissions to the atmosphere.  We use field measurements  and data analysis to quantify methane emissions and understand subsurface leakage processes, which are critical for engineering effective mitigation strategies. 

Orphaned oil and gas wells are non-producing wells for which the responsible party is no longer available or is unable to plug the well and remediate the well site. As a result, governments and the general public are responsible for plugging and cleanup. 

ENERGY TRANSITION 

To reduce greenhouse gas emissions, alternative and renewable energy systems, including hydrogen, geothermal, and renewable natural gas, are actively being developed. We use measurements to quantify emission reductions achieved through these developments.  

DEEP GROUNDWATER 

Deep groundwater may be an important non-traditional water resource in the future. Therefore, deep groundwater aquifers needs to be protected from anthropogenic activities such as oil and gas production and waste disposal. We use data analysis and modeling to understand deep groundwater quality, quantity, and protection.
