Experimental Testing of New Generation Chemicals and Conventional Surfactants as Additives to Steam Injection
DownloadSpring 2019
With the decrease in nonrenewable energy sources, heavy oil and bitumen recovery gains more attention due to their huge potential. The recovery of heavy oil or bitumen requires viscosity reduction where steam is commonly injected to mobilize and displace viscous oil. This application, however,...

Predicting Waterflooding Performance in Low-permeability Reservoirs with Linear Dynamical System
DownloadFall 2016
Several interwell connectivity models such as multiple linear regression (MLR) and the capacitance model (CM) have been proposed to model waterflooding performance in high-permeability reservoirs based on observed production data. However, the existing methods are not effective at characterizing...

Towards Accurate Density and Interfacial Tension Modeling for Carbon Dioxide/Water Mixtures
DownloadFall 2020
Phase behavior of carbon dioxide/water (CO2/H2O) binary mixtures plays an important role in various CO2-based industry processes, including CO2 injection for enhanced oil recovery and CO2 storage in saline aquifers. Engineering design of such processes requires an appropriate thermodynamic model...
