چکیده

Sequence stratigraphy is a key step in interpretation of the seismic reflection data. It was originally developed by seismic specialists, and then the usage of high-resolution well logs and core data was taken into consideration in its implementation. The current paper aims in performing sequence stratigraphy using three-dimensional seismic data, well logs (gamma ray, sonic, porosity, density, water saturation and resistivity) on Hendijan oil field located in the northwest part of Persian Gulf. , Depth interval of the study that covered from Asmari formation to Kajhdumi formation was determined by using well markers. Based on the depositional sequence model that consists of four systems tracts and with the help of Wheeler diagram, observed patterns have been used in seismic reflection terminations to identify sequence boundaries, systems tracts and internal stratigraphic surfaces in the sequences. Additionally, well logs were interpreted for two objectives. Firstly, variation patterns of well logs were used to validate sequences, their components and internal sequence stratigraphic surfaces. Secondly, the well log data was used for characterization of systems tracts with the log values.
This paper addresses the constraints patterns for such stratigraphic problems in seismic interpretation with the aim of achieving better chrono-stratigraphic reasoning system with previous studies in Iran.
