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?

Which one of the following phenomena encountered during flooding is desirable for increasing oil recovery from a reservoir?
Match the Enhanced Oil Recovery (EOR) methods (GROUP I) with the corresponding laboratory tests (GROUP II).
| GROUP I | GROUP II |
|---|---|
| (P) Gas injection EOR | (I) Interfacial tension studies |
| (Q) In-situ combustion EOR | (II) Screen viscometer test |
| (R) Polymer flooding EOR | (III) Minimum miscibility pressure test |
| (S) Surfactant-Alkaline EOR | (IV) Oxidation cell test |
