Contribution À La Modélisation Structurale Et Pétrophysique Du Réservoir Cambrien Du Secteur Septentrional De La Zone « Up Side » Nord Du Champ De Hassi Messaoud (sud Algérien).

Résumé: This study provides a geological synthesis and a structural and petrophysical modeling of the Cambrian reservoir, "Outside the North Zone" which is located north of the Hassi Messaoud field. This zone is characterized by a stratigraphic series quite similar to that of the Hassi Méssaoud field. Composed by drains D4, D3, D2, ID and D1, Z-ps, R2ab. Structural modeling using the PETREL software shows that the study area is very affected by tectonics, for which the analysis of isobath maps has shown the existence of major fault in the NS direction and other secondary faults of EW direction which are almost perpendicular to the major faults. Petrophysical modeling allows us to deduce the best drains from this reservoir, regardless of the distribution of the petrophysical parameters are "ID and D1". But when taking into account the effect of Hercynian erosion on the D2 drain finds that the Intre drain also has acceptable petrophysical properties, because their extension is large compared to the D2, so this drain also remains a better objective. oil tanker.
