L’identification des zones productives dans les réservoirs schisteux (Cas de bassin de l’Ahnet)

Abstract

Global economic development derives mainly from energy that can be fossils such as hydrocarbons or renewable energy such as: nuclear power, wind power, and solar energy. Noting the rise in global energy demand, since the 18th century confirms that a new energy source can never replace the old one. The scientific subject of this work involving the exploration of shale gas in the foam is to evaluate the shale intervals in order to identify the productive zones (potential zones). The application of the shale reservoir evaluation approach proposed by Kadri.M.M and Hacini.M (2017) shows that the Lower Silurian in our study area represents the potential area that may contain readily recoverable gas. This study led us to the conclusion that: 1. The minimum resistance is within 10 ohm-m and 80 ppm for uranium grades. 2. The types of free gas between rock slabs are of the alkane type, with full predominance of methane.
