Splet05. okt. 2024 · Macroscopic sweep efficiency improvement Mobility ratio The main principle of using polymer is to reduce the water to oil mobility ratio. Mobility ratio (M) quantifies the mobility difference between the water and oil phases. During water flooding, the mobility ratio is calculated using Eq. 1 (Fan et al. 2024 ). SpletThe effect of mobility ratio is illustrated in Fig. 2. Basically, low mobility ratio is favorable to displace a fluid whereas high mobility ratio will reduce the sweep efficiency due to the...
SpletThere are three potential ways in which polymer flooding makes the oil recovery process more efficient: (1) through the effects of polymers on fractional flow, (2) by decreasing the water/oil mobility ratio, and (3) by diverting injected water from zones that have been swept.
