P156 First Arrival Seismic Tomography Based on Fat Ray B Ke* (BGP CNPC) J. Zhang (Xiamen University China) B. Chen (BGP CNPC) & B. Zhao (BGP CNPC) SUMMARY It is widely recognized nowadays that the first arrival seismic tomography is one of the robust ways to estimate the near surface velocity model. However the first arrival tomography is still less perfect. In this paper we introduce the fat ray into the first arrival seismic tomography in order to reduce the dimension of the null space of the tomography matrix and improve the resolution of the inversion results. Thus although the
