dc.description.abstractWettability is a profoundly important parameter need to be understood in reservoir engineering. It has direct impact on the nature of fluid trapping, residual oil saturations, and mechanisms of displacement at the pore scale. Unfortunately, this parameter is very difficult to measure in unconsolidated systems, such as the oil sands of northern Alberta. Furthermore, in oil sands where the oil viscosity is much higher than that of water, conventional Amott/USBM testing cannot be applied. Therefore alternative technologies should be considered. Previous researches have shown that NMR technology could be used for wettability characterization. This study systematically investigated the NMR signal variation trend on well characterized model samples under different wettability conditions, as well as the effect of viscosity of oil phase on NMR signal variation. A better understanding on the effects of wetting conditions and saturation on NMR T 2 relaxation variation were obtained for both water and oil phase. Based on these findings, the wettability condition derivations from fluid NMR signal distribution analysis were explained. Furthermore, the effect of connate water on oil sands wettability as well as the bitumen recovery from oil sands was also investigated.
