EoR in alternative cosmological scenarios
The aim of this Thesis is to investigate the possibility that the observations related to the epoch of reionization can probe not only the evolution of the IGM state, but also the cosmological background in which this process occurs. In fact, the history of the IGM ionization is indeed affected by …

Improvement of Carbon Dioxide EOR in Water-Wet Reservoirs by Using Active Carbonated Water
… CO2 from carbonated water into oil phases, a theoretical model is developed. The diffusion process is governed by diffusion coefficients of CO2 in water and oil phases. To determine these two diffusivities, an experimental method is proposed. In the experiment, two phases are placed in a closed …

Semantic model and updated screening criteria for polymer flooding
"Enhanced oil recovery (EOR) processes produce oil that conventional methods leave behind, where interfacial forces, heavy oil viscosity, and reservoir heterogeneity make it difficult to produce. Many EOR methods are available but usually cannot be used at the same time for a candidate reservoir. …
