Abstract

In this study from the processing and interpretation of the image log (EMI Log) and results integration with the results of the interpretation of conventional reservoir logs (full set logs) In order to describe the reservoir properties of Fahliyan Formation, has been used. Processing and interpretation of full set and image logs in Geolog specialized software. The findings of this study are based on the processing and interpretation of the EMI image log, the dip of the layering is less than 10 degrees and along the northeast. Also, the development of fractures in this limited formation, and generally fractures are open and along the South-West. The maximum tension is also detected in the direction of North East-South-West (NE-SW). The processing and interpretation of conventional reservoir diagrams also shows that the Fahliyan Formation in one of the oil fields of Abadan plain can be divided into 6 layers (F1, F2, F3, R1, F4, and R2). The layers of R1, R2 show weak reservoir potential and F1, F2, F3, and F4 layers are basically lacking reservoir potential due to their very poor porosity or high shale volume. The present study is an applied study. With regard to drilling ranges and reservoir conditions (poor) and considering the costs of drilling, operation and processing, this field is not suitable for development at present and in case of development, due to poor reservoir conditions, it will be necessary to stimulate formation, including acidification.
