Effect of heterogeneity on engineered water injection in carbonates using five-spot sector model: A numerical study

One of the promising and emerging enhanced oil recovery techniques in both sandstones and carbonates is engineered water injection (EWI). However, few studies discussed the field-scale applications of this technique in heterogeneous carbonate formations. This paper is an extension of our previous work of the EWI technology at core-scale. This research numerically investigates heterogeneity effect on EWI technique in carbonates at field-scale using five-spot models. Three synthetic five-spot sector models were considered including homogeneous, heterogeneous with permeability channeling, and heterogeneous with gravity underride.
