  • In oil recovery from fractured reservoirs, Dynamic Spontaneous Imbibition (DSI) plays an important role. Conventional equations used to characterize DSI neglect interfacial coupling effects (ICE). Moreover, no numerical model has considered a variable inlet saturation (S*) for DSI. An iteration scheme has been developed to solve Bentsen’s Transport Equation using a Lagrangian Formulation for which initial and boundary conditions have been derived to take into account a variable S* and ICE. A sensitivity analysis has been conducted to study the effect of the fluid and rock properties on DSI. The results reveal that including a variable S* has insignificant impact; however, neglecting ICE results in an overestimation of the imbibition flow rate. It is important to mention that, based on the results of this study, the capillary and relative permeability curves determine the type of frontal advance, and that the imbibition recovery is proportional to the square root of time.
