Caractérisation et évaluation quantitative du réservoir cambro-ordovicien de la structure de Hassi Guettar ouest

Abstract

Hassi Guettar West is one of the peripheral zones of the Hassi Messaoud field recently exploited, it presents a more complex structure compared to the main zones of the field but in the last time, a pressure drop in particular the pressures in head Pt was noticed The main aim of this work is the characterization and quantitative evaluation of the CambroOrdovician reservoir of the structure of Hassi Guettar West and the treatment of the major problems of this deposit and for this the method used to estimate the reserves in place (OOIP this is the method of simulation of reservoir pressures. Using measured (actual) field pressures from well tests (DST, Build-Up, PFS) during production history. The pressure setting is done between the PG well test and the MBAL (PG balance) software simulated pressure, which is varied according to OOIP values entered each time.
