Evaluation of laminated shaly sand sequences in Ahwaz oil field using (via) Thomas Stieber method and conventional petrophysical logs

In this paper laminated shaly sand layers (LSS) are studied by using Thomas Stieber model and conventional petrophysical logs. Thomas Stieber model was applied to the desired layer by laminated shaly sand analysis module in Geolog 7.2 software and the results of the model and conventional petrophysical logs were analyzed by using this software. Finally, by comparing the results of the analysis, it was concluded that Thomas Stieber model calculates properties of laminated shaly sand layers more accurately than the conventional petrophysical logs and this model can be used in the study of these sequences.
