Modeling of Reactive Flow in Carbonate Rocks with Continuum Approach from Pore Scale to Core Scale
, M.Sc. Thesis Sharif University of Technology ; Ayatollahi, Shahabeddin (Supervisor)
Abstract
Carbonate reservoir acidizing is one of the most important well stimulation operations that has been widely used in recent years. Modeling the operation prior to any laboratory tests has always been one of the motivations of scientists in recent years due to the complexity of modeling to consider both mass transfer and reaction phenomena. There are several models have been proposed to simulate the acid injection process in carbonate rocks in recent years, the most important one is the Two-Scale Continuum Model (TSCM). This model utilizes the combination of Darcy-scale transfer and reaction equations and a series of pore scale relations to investigate acid injection into two-dimensional...
Experimental and Simulation Study to Determine the Fracture Flow Functions in Two Phase Systems at Core Scale
, M.Sc. Thesis Sharif University of Technology ; Ghazanfari, Mohammad Hossein (Supervisor)
Abstract
Fractured reservoirs have allocated a significant portion of Iran's and the world's oil and gas reserves, underscoring the importance of predicting the performance of these reservoir types in the oil and gas industry. Predicting the performance of fractured reservoirs by professional reservoir simulators, especially in enhanced recovery conditions, requires precise information on fracture flow functions, which is often limited. These functions vary for each reservoir based on the distinct characteristics of the rock and fluid, and the only way to determine them is through appropriate laboratory experimentation and modeling of the results. Currently, in simulation models, the relative...
