The oil recovery factor, areal sweep efficiency, and remaining oil saturation in two different injection-production well patterns are summarized in Table 4.
The areal sweep efficiency of horizontal well is 17.2% larger than vertical injection well, and the final recovery factor of horizontal injection well is 7.62% higher than vertical injection well.
