Tidal Channels in Carbonate Platform - Taking Azadegan Oilfiled as an Example

Sarvak formation of Azadegan oilfield is a carbonate serial in Upper Cretaceous of Middle East. Some particular geobodies as tidal channels were recognized by exploration and geological research. Through the study of sedimentology, the geological setting of tidal channels in Sarvak formation was discussed, confirming that these channels developed in rimmed shelf carbonate platform. The tidal channels that developed in the platform have high energy conditions; therefore this kind of tidal channels is the areas with favour reservoirs, playing an important role in oil&gas exploration.
