ABSTRACT: Interpretation of 2-D Reflection Previous HitSeismicNext Hit Data and Previous HitSeismicNext Hit Stratigraphy of Darquain Field, SW of IRAN

The Major objective of this research is Previous HitseismicNext Hit stratigraphy of Darquain Oil field which is located in the south-west of Iran, 45 km of the north-east Abadan. Previous HitSeismicNext Hit data are collected along 9 Previous HitseismicNext Hit profiles, and there are only three exploration wells in the area. Geologically, the area is located in Dezful depression. The sedimentary basin under investigation formed during lower to middle Jurassic. Major reservoir rocks of the field are Khami and Bangestan groups.

There are no faulting and structure complexity in Darquain field and the field is a gentle anticline with double plunge. General trend of the structure is NE-SW which is different from adjacent structures.

For interpretation of existing Previous HitseismicNext Hit profiles in the area, 11 Previous HitseismicNext Hit surfaces were selected. The time contour maps of the above mentioned surfaces were generated using Geoframe Software.

On the basis of Previous HitseismicNext Hit data, 5 Previous HitseismicNext Hit sequences and 7 Previous HitseismicNext Hit facies were recognized. Correlating the Previous HitseismicNext Hit profiles, lateral changes of the Previous HitseismicNext Hit facies were also investigated. This study shows that in the area along the investigated Previous HitseismicNext Hit surfaces, with increasing carbonate content, the amplitude and continuity of Previous HitseismicNext Hit reflections increase. Neverthless, the amplitude and continuity of the reflections decrease with increasing the fine sediments content and the porosity of carbonates

This interpretation which are obtained from integration and comparison of Previous HitseismicTop and well data can be utilized for reservoir quality prediction for the area in which there is no well data available.
