Abstract
Summary
The Wadi Sahba is a depression located in Central Saudi Arabia. Seismic imaging of this zone is challenging due to scattering related to faults and velocity variations in the near surface. This paper present a study using WAVSP data to provide seismic images around a well located inside the wadi. The study included analysis of anisotropy of the area, using data acquired inside and outside the wadi. The seismic anisotropy was identified as one of the possible causes of poor imaging in the Wadi Sahba. Anisotropic imaging contributed to the reduction of misties and to the enhancement of lateral imaging.
