    摘要: A method of treating a hydrocarbon containing formation, comprising the following steps:
    (i) drilling a first well (5), in the hydrocarbon containing formation,
    (ii) introducing heating means (13) into the first well,
    (iii) drilling a second and a third well in the hydrocarbon containing formation, said second and third wells being parallel to the first well,
    (iv) applying heat to the hydrocarbon containing formation, and simultaneously,
    (v) injecting a flooding fluid into the hydrocarbon containing formation through the second and the third well, wherein the flooding fluid is a water composition with a viscosity superior or equal to 10 mPa.s, and
    (vi) extracting hydrocarbon from the hydrocarbon containing formation.
