Study of Oil Recovery Method through Chemical Injection in order to Improve Oil Exploitation

Abstract

Today, the primary recovery of hydrocarbon reservoirs producing oil fields in the world due to natural The mechanism is done. But over the lifetime of reservoir to reduce the pressure of oil in the pores of the reservoir rock trapped. Therefore, for optimal harvest subsurface reservoir due to reservoir conditions, specific methods can be considered. Chemical injection method in order to change the viscosity of the fluid in the oil are stable displacement of the most efficient methods of increasing recovery of oil production in oil fields. The injection process chemicals such as alkalis, polymer and surfactant are concerned that the displacement of the reservoir oil below the surface. In this method of alkali impressing adsorption, has an important role in improving the efficiency of the injection system. Also, in this method of polymer, the improvement of mobility, and Surfactants reduce the surface tension. In the present study enhanced oil recovery by injecting chemicals is studied
