Depositional Environment, Sequence Stratigraphy, Quality and Deployment of Reservoir Zones in the Kangan Formation in the Tabnak Anticline (Southern Zagros)

Abstract:

The Kangan Formation (Early Triassic) is one of the most important source rocks in the gas fields of the southern Zagros and the northern Persian Gulf. The studied gas field is located in the west of Hormozgan province and is one of the most important gas fields in Iran and the world. In order to evaluate the depositional environment and sedimentary sequences of this formation in the wells, microscopic studies as well as analysis of petrophysical charts, especially gamma-ray log, have been studied which this resulted in the identification of seven microfacies, of which these facies were deposited in four depositional subenvironments as tidal flat, lagoon, mainly shoal and open marine, and two third-order sedimentary sequences with a second-order sequence boundary (correlative conformity), each of which consists of a system tract of TST (often consisting of tidal flat and lagoon facies) and HST (often containing shoal facies) was formed. This study was also carried out with the aim of investigating the quality and expansion of reservoir zones and its relation with sedimentary sequence and depositional environments. In previous studies, the Kangan Formation has been classified into four general zones in terms of petrologic characteristics, but in this research with relying on available digital files from well studies and extending this information in the software space, and finally combining the interpretive information of the existing output charts, including gamma-ray logs, sonic log, density log, effective porosity log, and stratigraphic column with thin sections and sedimentary sequences, Kangan Formation in the well of the field was divided into three general zones in terms of reservoir.
