Abstract: GeoEast V2.0 seismic data processing and interpretation software system is developed on the basis of GeoEast V1.0 after some functions of the software platform are improved and optimized, such as system control, information communications and data management. The new version is added with a series of creative results - seismic data processing, new interpretation function, super-large seismic data management, high-efficiency calculation of PC-Cluster group system, and unified system communications. With a series of relatively perfect conventional processing and interpretation functions for onshore and offshore 2D and 3D seismic data, GeoEast V2.0 is technologically leading in the areas of noise suppression, static correction of complex areas, complicated structural imaging, VSP and multiple data processing, identification of small faults and fractures, and selection and application of modern attributes. It can process and manage a hundred of TB data, process a thousand of CPU/GPU clusters in parallel, and jointly interpret a hundred of square kilometers of 2D and 3D data at the basin level, helping CNPC improve its geophysical technological competitiveness on the international market. It is one of the world’s few software systems that can provide full technological support for oil and gas exploration and development.
