This work presents a new method based on the recovery‐curve method to evaluate the in situ rock wettability in naturally fractured reservoirs. The recovery‐curve method uses recovery curves to describe more realistically the matrix–fracture interactions. The capability of the proposed method was shown in two models, namely a simple column model and a realistic naturally fractured reservoir. Appropriate recovery curves were determined by history matching the movement of the water–oil contact. The slopes of the obtained recovery curves were analyzed with the method presented by Mirzaei‐Paiaman et al.,12 which is referred to as the MPMS method in this study. The MPMS method has many advantages over other methods. Proper indices describing in situ rock wettability states were determined. The results are in very good agreement with those obtained from conventional methods.
