Dear all,

It is my pleasure to invite you to my PhD defense. 

Title: Greenhouse gas detection in the energy system: an integration of remote sensing and GIS database

Abstract: The oil and gas (O&G) system significantly contributes to global anthropogenic greenhouse gas emissions (GHGs). The rapid development of remote sensing technologies enables direct measuring of point-source GHGs within the O&G system. These technologies, known as “top-down” methods, demonstrated their capabilities in measuring methane, carbon dioxide, and gas flaring by collecting radiance in the shortwave infrared using airborne or spaceborne remote sensors. This study aims to enhance our understanding of GHGs in the O&G system using remote sensing and geographic information system (GIS) techniques. We first estimated field-level gas flaring volumes using the satellite gas flaring data and a global O&G field GIS database. We then introduced an improved method for detecting and quantifying methane emissions based on Sentinel-2 satellite imagery. Finally, we applied imaging spectroscopy methods to measure carbon dioxide emissions within the liquefied natural gas (LNG) supply chain, with a particular focus on LNG terminals.
