Transverse relaxation in sandstones due to the effect of internal field gradients and characterizing the pore structure of vuggy carbonates using NMR and Tracer analysis
Nuclear magnetic resonance (NMR) has become an indispensable tool in petroleum industry for formation evaluation. This dissertation addresses two problems. • We aim at developing a theory to better understand the phenomena ...
Study of Foam Mobility Control in Surfactant Enhanced Oil Recovery Processes in One-Dimensional, Heterogeneous Two-Dimensional, and Micro Model Systems
The focus of this thesis was conducting experiments which would help in understanding mechanisms and in design of surfactant enhanced oil recovery (EOR) processes in various scenarios close to reservoir conditions such as ...
Influence of Electrostatic Potential to Wettability in Brine-Oil-Minerals System
This study improves the microscopic understanding of electrostatic potential to a reservoir’s wettability, defined as the tendency of oil-wet or water-wet. Current conclusions about the wettability of oil reservoirs continue ...
Transport of Surfactant and Foam in Porous Media for Enhanced Oil Recovery Processes
The use of foam-forming surfactants offers promise to improve sweep efficiency and mobility control for enhanced oil recovery (EOR). This thesis provides an in depth understanding of transport of surfactant and foam through ...
