Evaluation Du Réservoir Par Carottage, Comparaison Avec L’imagerie, Et Étude Géomécanique De Quartzite El Hamra De Puits Hdz-17

Résumé: The heterogeneity of the Hassi Messaoud reservoirs results from a complex and important geological and structural evolution, this heterogeneity to complicate the evaluation of reservoirs. Well HDZ-17 located in the Hassi D'zabat field, the latter is part of the outskirts of Hassi Messaoud, it produces oil in the Ordovician, specifically in the Quartzite El Hamra, the latter is a compact rock and fractured, which produces by cracking. Imaging is an advanced technology, less expensive than coring, and provides representative information on reservoir fracturing, such as coring. Our study is intended to verify the reliability of the information obtained by the imagery, so we followed the following methodology:  Tank evaluation by visual description of the core, and then a simple statistical analysis of the porosity and permeability.  Comparison between the analyzes obtained by the coring, and those obtained by the imagery.  Confirmation with the result of geomechanical tests, by determination of geomechanical, static and dynamic parameters, then estimation of the three constraints, and finally comparison between the two.
