Abstract: Bureau of Geophysical Prospecting (BGP) has committed its efforts to the challenges for China’s hydrocarbon exploration, such as the onshore exploration targets changing from structural reservoirs to subtle reservoirs and the survey areas shifting from simple near and subsurface structures to complex ones. The bottlenecks also include difficulties for imaging steeply dipping reflectors and highly-faulted small blocks. Based on conventional processing and interpretation technology of GeoEast and focusing on high-density and wide-azimuth seismic data, BGP has developed and integrated eight categories of the advanced and applicable seismic data processing and interpretation technology-pre -stack migration imaging, low SNR processing, resolution enhancement, MC data processing, modern attribute analysis, geo - body rendering, reservoir description and fluid detection. With the GeoEast V3. 0 version developed, BGP has significantly improved functions and performance of the software and entirely met the demand for processing and interpretation of onshore, offshore, MC and VSP data.
