Understanding the Oil Recovery Challenge of Water Drive Fractured Reservoirs

Improving or Enhancing the oil recovery appears as a challenge for many porous fractured carbonate reservoirs as<br>unfavourable conditions for matrix oil production are often encountered, such as a low permeability or a weak water<br>wettability of the matrix medium. The selection, optimization and risk minimization of a production scenario for such fields<br>goes through a clear understanding of the underlying physical mechanisms, together with a sufficient characterization of the<br>fracture network and the evaluation of determinant matrix properties.
