GPU-accelerated reverse time migration and its application

There are many difficulties in reverse time migration applications for nowadays seismic exploration, storage and computations of the mass data may be the top ones. In this paper we use source reconstruction method to reduce mass storage brought by cross-correlation imaging condition, and introduce GPU kernel to improve computation efficiency. And based on these, we build a GPU accelerated reverse time migration method, which successfully applied in Block A, a complex area in Sichuan Basin.
