The effect of gravity on oil recovery was studied in a Hele‐Shaw cell. An immiscible two fluid system consisting of light paraffin oil as the displaced phase and distilled water as the displacing phase was used. Oil recovery at breakthrough was found to be almost linearly dependent on the Bond number. Maximum recovery was obtained in the case of upward flooding with the cell positioned vertically. The minimum oil recovery occurred when flooding was performed in the downward direction with the cell also placed in the vertical position. The recovery results obtained for the experiments carried out at a 45 degree incline and in the horizontal position were situated between these extremes.
