Sedimentological and Sequence Stratigraphic Study of the Hanifa Reservoir in a Giant Field in Central Arabia, Saudi Arabia

M.I. Fallatah¹ and M.H. Alnazghah¹

Abstract

The Hanifa reservoir, forms the upper part of the Ulayyah Member, was deposited during the Late Jurassic over a period of 5.5 Ma. It is one of three oil-bearing carbonate reservoirs in the study area. To optimally develop the reservoir, a better understanding of the reservoir’s stratigraphy and depositional settings is required. The aim of this study is to generate a high-resolution sequence stratigraphic framework for the Hanifa reservoir using the principles of modern sequence stratigraphy. To achieve that, a total of eleven cored wells were described and used to construct north-south transect along the Field. Wireline logs, including gamma ray, neutron and density, were used to correlate between wells.
