Abstract
In this presentation, we introduce contents and some of their result of
the joint research project titled by the 'Advanced Seismic Imaging
Technology' (hereafter ASIT) originally conducted by JNOC/TRC since
1993. The purpose of this project is to establish a technology of
accurate seismic depth imaging for oil exploration, specially for the
exploration area which has complicated subsurfaces such as saltdome and
overthrust and so on. This project has been jointly operated by JAPEX,
JGI and JNOC/TRC.
Phase 1 of ASIT project was conducted between 1993 and 1997. Following
it, Phase 2 started since 1998. During Phase 1, 2 dimensional (hereafter
D) depth imaging technology such as prestack depth migration together
with 2D velocity analysis method was mainly developed. We also
developed 3D seismic simulation software.
In Phase 2, we are now extending dimension from 2 to 3 by using powerful
supporting tool such as 3D visualization tool and a super computing
system. The 3D depth imaging system will be developed newly in Phase 2
and it should deal with not only marine seismic data but also land
seismic data usually acquired on surface with irregular geometry. Some
of result from ASIT project will be shown in presentation.
