A number of experiments have been performed to study water injection in fractured porous media. These experiments reveal that: (1) the co-current imbibition may be the primary flow process in water-wet fractured media, and (2) the imbibition may result in over 20 percent recovery from very tight rock (Austin Chalk with K{sub ma} of the order of 0.01 md) for an imbibition period of about 2 months. Theoretical consideration reveal that the exponential function of Aronofsky et al. [``A Model for the Mechanism of Oil Recovery from Porous Matrix Due to Water Invasion In Fractured Reservoirs,`` Trans. AIME (1958) 213, 17-19] does not describe the early-time, but may represent the late-time recovery
