CARACTERISATION DES RESERVOIRS DU CHAMP DE RHOURDE CHEGGA (GRES T1, GRES RDC ET QUARTZITES DE HAMRA) Nord-Est de Hassi Messaoud

Abstract

Hassi Messaoud is considered one of the largest oil fields in the world and the heterogeneity of the Hassi Messaoud reservoirs results from a geological evolution and structural complexity, this heterogeneity to complicate the evaluation of reservoir, at the end of the study of the different reservoirs of the Rhoud Chagga fields located in the north - east of Hassi Messaoud and proposed mainly in the Triassic (T1) - the Gres (DRC) and Quartzite de Hamra (QH); The work was presented as part of the evaluation of the geological characteristics of reservoir formations of the Rhourde Chegga field from a study:  preliminary sedimentological to be able to reconstitute the depositing environment  define the geometry and extension of the different reservoirs  as well as the interpretation of petrophysical data on the basis of geological characteristics  evaluate their influence on petrophysical parameters and the performance of each reservoir
