Synthèse géologique et caractérisation pétrophysique de la zone 06 du champ de Hassi Messaoud

Abstract

This study speaks about the geological synthesis of the Cambrian reservoir, "zone 06" which is located in the central part of the field of Hassi Messaoud. This area is characterized by a stratigraphic series quite similar to that of the field. The tank (R1) is represented by the (RA) is the productive reservoir : composed of drains D2, ID and D1. The RI level is eroded by the effect of the hercynian unconformity. In this framework we have established the following studies: A structural study carried out for the purpose of establishment and interpretation of the geological sections of the different generally crossing the reservoir part and the interpretation of the maps in isobath to the roof and the reservoir wall. A sedimentological study, which mainly based on the description of the cores to determine the facies and the different deposition environments. The petrophysic study is based on the statistical interpretation of the petrophysical parameters (porosity, permeability) of the various drains constituent the Cambrian reservoir using the different software (Petrel, Statistica), which allows the realization of the maps in ISO-porosity and Iso-permeability at the end of the data the representations of histograms and graphs of probability of the petrophysics parameter.
