E038 Wave Equation Datuming Using Explicit Wavefield Extrapolation from an Irregular Surface S.M. Al-Saleh* (Saudi Aramco) S.K. Kellogg (Saudi Aramco) & G.M. Margrave (University of Calgary) SUMMARY Rugged topography and an underdetermined complex near surface are some of the most important challenges for onshore seismic data processing. For any complex near surface the conventional stationary datum static corrections might fail to resolve the surface and near surface related problems. Wave equation datuming (WED) techniques offer more accurate solutions to these issues; however most of them are based on ray-theory such as the Kirchhoff methods. That is they are not as
