Abstract

The Albian-TuronianSARVAK FORMATION is one of the main oil reservoirs in south and southwest Iran that hosts significant amount of hydrocarbon resources in this region. Facies analysis in seven oil fields of PERSIAN GULF led to identification of 7 microfaceis that are deposited in four facies belts in a homoclinal ramp platform. Studies show that there is major facies variation in Sarvak carbonates of offshore Zagros. The rudistbearing facies are mainly developed as major reservoir facies in the eastern PERSIAN GULF (Siri Fields) and replaced with mud-dominated lagoonalfacies in central and western sectors of considered area (Hendijan, Bahregansar, Balal and Lavan Fields). There are positive correlation between paleogeographic position of rudist buildups and configuration of Sarvak reservoir in the PERSIAN GULF. Main diagenetic processes that effected facies of this formation are neomorphism, bioturbation, micritization, dolomitization, dissolution, cementation, stylolitization and fracturing. During diagenesis, rudist-dominated facies are selectively dissolved and led to development porosity and reservoir quality in the Siri Fields. Generally, diagenesis is slightly impacted reservoir properties in the central and western parts oil fields, although, dolomitization is improved reservoir characteristics in the Bahregansar Field. Petrophysical evolution of studied intervals suggests that good reservoir intervals are associated with rudist-bearing facies. As well, there are decreasing trend in both porosity and permeability values from top of formation downwards, particularly in Siri fields. This trend is attributed to effect of meteoric diagenetic under the Turonian unconformity. In conclusion, our studies indicate that occurrence and evolution of rudists had main impact on diagenetic modification and reservoir potential of SARVAK FORMATION.
