E037 Straight Ray Datuming in 3D Media – Fast and Flexible T.A. Alkhalifah* (KACST) H. Innemee (Spectrum Energy and Information Technology Ltd) & C. Benson (Spectrum Energy and Information Technology Ltd) SUMMARY Common datuming approaches like the Kirchhoff or finite difference methods are rarely applied to 3-D conventional land acquired data because they require reasonable sampling of the sources and receivers which is not often the case with such data. To combat that we extend Alkhalifah and Bagiani’s (2006) straight ray datuming (SRD) to handle 3-D acquisition geometries. Like in the 2-D case 3-D SRD is based on straight-rays assumption
