Waterflood efficiency of a fissured oil field is closely dependant on the volume and speed of water imbibition in the elementary blocks. Numberous laboratory tests have been performed on fluids and porous media taken from a field exploited by ELF, and have helped to ascertain the effect of the blocks height and permeability, and the conditions at their limits as well (some fissures may contain water or oil or may be tight), on oil recovery. The results show how important are the physico-chemical bondings between connate water, injected brine, oil, and rock at any time during imbibition: minor differences in lithology may considerably alter the recovery laws. Similarly, some organic molecules in the fluids influence oil recovery much more than one might expect according to the variations of phi cos theta alone. As one does not know how to represent these physico-chemical bondings, it is not permitted to perform laboratory experiments with fluids and/or core different from the real one (except for special cases). Laboratory measurements, together with numerical simulations, have given results which allow understanding the role played by gravity, capillarity, boundary conditions, and end affects on the ambibition.
