Detailed core description of multiple wells within a giant gas field in the United Arab Emirates (UAE) has enhanced the understanding of the depositional make-up and possible controls on depositional style for the Arab Formation.
The main objectives of this study were to better understand the distribution, orientation and type of channel bodies within successive layers of the Triassic Argilo-Grèseux inférieur (TAGI) reservoir in the Ourhoud field through the integration of core and Ultrasonic Borehole Image (UBI) datasets from 37 wells.
This study shows that constructing a sedimentological framework for the Asl and Hawara Members can assist in understanding reservoir geometries that can lead to a predictive tool for future reservoir potential.
This study uses over 30 UBI datasets calibrated with 22 fully cored wells to assess the dominant fluvial facies and their distribution within a refined reservoir zonation in order to constrain reservoir architecture and modelling scenarios.
This study uses data from over 120 cored wells to refine the stratigraphic and depositional model, and to determine the reservoir architecture and heterogeneities within the field.
This study uses data from 4 cored wells to evaluate the controls on reservoir quality, and integrate these results with the sedimentological framework in order better understand reservoir quality distribution within the Zubair Formation.
