چکیده مقاله
In this paper we perform dynamic imbibition simulations on a large scale homogenous fractured block The purpose is to seek optimum conditions under which the oil recovery is maximal in a larger scale model In order to do this, we consider 7 different cases with varying relative importance of capillarity and viscous forces 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, even though 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 case number and appropriate profiles are demonstrated in order to understand the results
