Evaluation of petrophysical parameters and study sedimentology of Zone N°23 (Hassi Messaoud region)

Abstract

Discovered in 1956, the Hassi Messaoud field in the northern Sahara Basin is one of the world's largest oilfields. Its wealth lies in a reservoir made up of thick layers of quartz sandstone dating from the Cambrian and Ordovician eras. Zone 23, the focus of this study, lies to the southwest of this oil giant. An in-depth analysis of Zone 23 was carried out using Petrel software, enabling detailed study of the deposit's petrological and physical properties, such as porosity and permeability. The results, presented in the form of isopycnal porosity and permeability maps, revealed a remarkable correlation between these properties and the quality of hydrocarbon production in the zone. The benefits of this study are considerable, including: an in-depth understanding of the characteristics of the Hassi Messaoud field, in particular zone 23; the identification of factors influencing hydrocarbon production efficiency in the study area; and valuable information for oil and gas companies operating in the area, enabling them to optimize their exploration and production processes.
