Chemical Reagents for Increasing the Water Flooding Efficiency in Oil Reservoirs

A. A. Dunenova and E. S. Oryngozhin

In order to improve the water flooding efficiency in oil reservoirs, water viscosity is increased by the addition of polymers in it. Polymers represent class of substances with specific properties due to the presence of giant chain structure molecules. During oil displacement, polymeric reagents increases the sweep efficiency by decreasing the mobility ratio of water to oil. The article examines the effectiveness of polymers and polymer flooding.
