A Field-Scale Simulation Study of Surfactant and Polymer Flooding in Sandstone Heterogeneous Reservoir

Abstract

In the current work, three scenarios were considered including water, polymer, and surfactant/polymer flooding for a heterogeneous sandstone reservoir in the Asmari Field located at the South West of Iran in a simulation work. No injection of chemical flooding has been done on this typical reservoir. Most of Enhanced Oil Recovery methods were considered to be water and gas injection in this reservoir so far. UTCHEM was used as a 3D, and compositional simulator to model of chemical flooding process. Sensitivity analyses of vital parameters have been carried out and the results of simulation work were presented.

The Importance of Microemulsion for the Surfactant Injection Process in Enhanced Oil Recovery

“…Changes in wettability play a very important role in the mobilization of residual oil. In porous media filled with two or more immiscible fluids, wettability is a measurement of which fluid can wet (spread or adhere to) the surface [42]. In a water-wet system where the rocks are filled with oil and water, water will occupy the smallest pores and wet most of the surface in the larger pores.…”
