Experimental Investigation on the Performance of Preformed Particle Gel in Improving Oil Recovery by Low Salinity Water Injection in Heterogeneous Porous Media
, M.Sc. Thesis Sharif University of Technology ; Ghazanfare, Mohammad Hossein (Supervisor) ; Fatemi, Mobin (Supervisor)
Abstract
Water production from high permeability regions such as fractures and channels in the reservoir can be considered as one of the problematic issues in oil production. In order to control water production, chemical methods such as polymer injection, surfactant injection, and foam injection are widely used, among all of them, Preformed Particle Gel (PPG) is the most efficient method.By injecting the preformed particle gel into the reservoir and blockage of fractures and high permeable regions, Injected water bypasses to the target zone. In this study, preformed gel with a unique formulation was synthesized by free radical polymerization method in the laboratory.Nano-Clay and Nano-Silica were...

Abstract
Nowadays, application of ultrasonic wave technology as a novel method of enhancing oil recovery and also gas and oil well stimulation is prevailing. Not only this method is environment friendly, but also it is economic. Although the application of this method is proved to be of outstanding positive influences in field operations. In this study, it is intended to investigate the effect of ultrasonic waves on the rate and final recovery of miscible and immiscible injection of fluids as Enhanced Oil Recovery (EOR) methods by using the Micro model apparatus and Although the effect of the waves on fluid flow through the porous media can be studied. The results of this work are a good guidance to...
