Summary:
The Early Cretaceous (Barremian-Aptian) Upper Sandstone (Main Pay) Member of the Zubair Formation is the main producing reservoir in the supergiant Rumaila oil field of southeast Iraq. Whilst the field has been on production for c. 60 years, significant resources remain. Key to their economic development is an improved subsurface description based on the synthesis of diverse static and dynamic data. Geological heterogeneities at a range of scales impact reservoir performance, reservoir management decisions and future field development strategies.
