Certainly hydrocarbons will remain as key elements in the development of global economy in coming decades. Hence securing the growing global energy need requires special attention to energy saving. Considering this issue helps world move in a more sustainable way towards a better future. The downstream oil industry as one of the major industrial energy consumers will play its special role in the development and promotion of efficient and rational use of energy. The purpose of this paper is to introduce the opportunities facing downstream oil industry making it realizing this goal.<\div>

In this paper, we simulate dynamic imbibition on a small scale homogenous fractured block. The purpose is to seek optimum conditions under which the oil recovery is maximal. In order to do this, we consider a base case simulation and then we dosensitivity analyses on several parameters. The injections are all continuous. Various chemical solutions are injected. These include: water, polymer, surfactant, alkali, and different combinations of them. For convenience of simulation, although this is not physically correct, alkali represents the wettability modifying agent, while the surfactant is the agent that lowers the IFT to ultra–low values. Therefore, a simulation labeled AS indicates that the injected chemical solution lowers the IFT to ultra low values as well as alters the wettability from mixed–wet to water–wet. On the other hand, a simulation labeled ASP does the above task as well as making the chemical solution viscous (polymer). The recovery curves are compared for each sensitivity analysis and appropriate profiles are demonstrated in order to understand the results.<\div>

As a relatively new technology of tertiary oil recovery, alkaline\surfactant\polymer (ASP) flooding has been studied extensively in the last two decades. ASP flooding enhances oil recovery through two maJor mechanisms: increasing the viscosity of displacing solution to improve the sweep efficiency by using polymer and reducing oil– water interfacial tension (IFT) to a very low value (10–3 mN\m) to improve the pore level displacement efficiency through the synergetic effect of surfactant and alkaline.Field tests and laboratory studies have shown that ASP flooding is more efficient than any single component flooding, such as alkaline, surfactant, or polymer flooding.At present, it is a promising tertiary recovery method and is getting increasingly more attention.<\div>
