Abstract
On the average, conventional production methods will produce from a reservoir about 30 % of the initial oil in place. The remaining oil, nearly 70 % of the initial resource, is a large and attractive target for enhanced oil recovery methods. One of those methods is the chemical flooding which includes the polymer flooding process. This one depends on the viscosity of the polymer in use which affect on its sweeping efficiency and the hydrophobically modified polyacrylamides are recently among the polymers used in this important application. In this dissertation nine hydrophobically modified polyacrylamides were synthesized using nonionic Polymerizable surfactants by inverse microemulsion copolymerization and it is divided to three main parts:
