| Abstract: | This study investigated the property and composition of crude oils from in-situ combustion (ISC) and steam assisted gravity drainage (SAGD). We made comparison of the elemental composition and molecular weight distribution of the two crude oils. It was overserved that ISC crude oil has significant higher oxygen content. The ultra-high resolution mass spectrometry was applied to investigate the molecular composition of acidic compounds in two crude oils. The acidic compounds in ISC crude oil have higher carbon numbers than that of SAGD crude oils. |
