A reservoir model consisting of two porous matrices M and N, separated by a fracture, is shown in the figure. The matrices are strongly water-wet and are saturated with oil of specific gravity 0.8. Water is injected only in the fracture at injection well A. If the Reynolds number for the flow in the fracture conduit is assumed to be less than unity, which one of the following force will dominate oil recovery from the porous matrix M during the water-flood operation?

The initial water saturation in an oil reservoir with a free gas cap is 30%. The initial gas saturation is 40%. At the end of water flooding, all the free gases are dissolved due to the elevated pressure and the oil formation volume factor reaches a value of 1.20 rb/stb. The final water saturation at the end of water flooding is 50%. If the two-phase formation volume factor at the initiation of the water flood is 2.3 rb/stb, the pore-to-pore displacement efficiency under the current reservoir condition is ______ % (rounded off to one decimal place).

An oil droplet is to be mobilized by injecting water through a pore throat. The oil-water interface has the rear radius of curvature (r_A) of 25 x 10⁻⁶ m and a forward radius of curvature (r_B) of 5 x 10⁻⁶ m as shown in the figure. Assume that the pore is completely water wet (wetting contact angle is zero) and the interfacial tension between oil and water is 0.025 N/m.
The magnitude of the minimum pressure drop required to mobilize the trapped oil droplet is __________ N/m² (rounded to nearest integer).
