Synthesis Of Different Sizes & Functions Nanoparticles, Jiaming Geng
Masters Theses
"Nanogels, whose size range from 1 to 100nm, have been interested in many research areas: cosmetics, pharmaceuticals, catalysts, photochemistry, and in optical switches or sensors. In Petroleum Engineering area, nanogels can be used as conformance control agent and emulsion stabilizer. And after grafting functional groups or hybrid, nanogels can be used as tracer for the visual modeling.
Though nanoparticles have been studied for more than 20 years, few of them are about nanogels. In the thesis, stirring rate, surfactant type and concentration were found have a large impact on the synthesis of nanogels. And cationic nanogels have salt and acid …

Water channeling, one of the primary reservoir conformance problems, is caused by reservoir heterogeneities that lead to the development of high-permeability streaks and fractures. These streaks and fractures prevent large amounts of oil from being recovered. The ultimate objective of this research was to provide comprehensive insight into designing better particle gel treatments intended for use in large openings, including open fractures, high permeability streaks, and conduits to increase oil recovery and reduce water production.
An intensive laboratory study was conducted to better understand the injection and placement mechanisms of millimeter and micron size preformed particle gels (PPGs) through thief …
