Apport des Logging pour l’étude de l’évolution de paramètres pétrophysiques des Quartzites de Hamra dans le champ de BirSbaa

Abstract

Based on the data loggings, evaluation of Quartzite tank Hamra in the new field of Bir Sbaa was approached by a vertical division of the tank, followed by its petrophysical characterization. Three zones have been identified, zone 1, clay, thin, not rich clay and low values of porosity and permeability; Zones 2 and 3, thicker clay in poor and rich in silt and sandstones and better porosity and permeability. Zone 2 is a cylindrical type sequence resulting in a stable depositional environment while Zone 3 is a regressive sequence. The origin of the deposits of zones 2 and 3 is not too different. This is the same environment
