Abstract

A petroleum reservoir Study includes both characterization and evaluation of potential interval, in order to identify all parameters related to the reservoir (geology, petrophysics, logging, formation tests). For this study, 3 wells were selected (SF-2, SF-3, SF-4) in Berkin Basin, Southeast Algeria. The aim of the present paper is to discover the petrophysical quality of lower Triassic shaly sandstones reservoirs in Berkin Basin, perimeter Sif-Fatima. The results of laboratory petrophysical analysis suggests that the lower Triassic shaly sandstones is a good reservoir with high-quality of petrophysical parameters with an average core porosity and permeability of: 18.15% and 540.10 md respectively.
