Abstract: GeoEast-Lightening VI.0 software is one-way wave equation pre-stack depth migration software system designed to meet oil and gas exploration and development demand and facilitate a large-scale calculation on cluster with interactive job management. Its RMT function can be operated on GPU-CPU heterogeneous multi-core clusters for 2D and 3D seismic data imaging. It has been widely used in exploration of oil and gas resources. To meet the demand for seismic imaging technology for increasingly complicated oil and gas exploration and break international technological blockage, BGP started to develop “GeoEast-Lightening wave equation pre-stack depth migration software” in 2009 for the purpose to develop RMT software with independent intellectual property right. This software takes the lead in realizing large-scale application and industrialization of RMT in China. This technology reached international advanced level of its kind, with some technological targets leading the world in this area.
