The Arabian Peninsula is plagued with a complex near-surface that has a destructive influence on the final seismic image. This is especially evident on a line acquired from the Delim region of central Saudi Arabia. We use high-resolution shallow seismic data to resolve the complex near surface and correct the conventional data. High-resolution shallow data allow us, if the conditions for preserving high frequencies are present, to estimate the velocity at the near surface at a higher resolution. We use such information as inputs in the near surface correction step and thus correct the deep data for the near surface. The application of this approach on the Delim 2-D seismic line provided superior results than what was obtained from previous applications. Though, our focused conventional approach provided similar results putting more emphasis on focused analysis of the infected area.
