Chasing Permian Dune Sandstones in Central Saudi Arabia

B045 CHASING PERMIAN DUNE SANDSTONES IN CENTRAL SAUDI ARABIA Summary 1 Interpretation of a large 3D seismic volume from central Saudi Arabia has shed new light on the local structure and depositional history of the Permian Unayzah A Reservoir. A remarkably linear Unayzah valley well-imaged in the 3D volume was found to be oriented perpendicular to most other depositional trends of the Unayzah A. Additional integration of the seismic with well logs core descriptions and test analyses has further underscored the complexity of what was previously thought to be a somewhat simpler unit.
