(along horizontal wells), surfactant treatment/flooding, water imbibition, thermal treatment and acidisation. Tight reservoirs are primarily produced by hydraulic fracturing, surfactant treatment/flooding, water imbibition, application of electrokinetic potential and acidisation.

The process of selecting an appropriate approach is an important aspect of the routine because of the disparity in different types of unconventional reservoirs and the availability of a seemingly wide range of options of stimulating techniques. A thorough site reconnaissance and an assessment of the effectiveness, efficiency and impact of the selected method is indispensable. These should consider, amongst other factors, reservoir productivity, cost, environmental impact, and health and safety.
