Abstract

General Purpose GPU technology has being becoming mature, it has been applied in many industry area. However, due to the differences of computing feather between CPU and GPU, the study of GPU in petroleum industry application should be developed effectively. In this article, we introduce the General Purpose GPU technology and propose a method to realize prestack time migration software on GPU. Compared with traditional pre-stack time migration running on Personal Computer (PC) or PC-Cluster, the new programming method greatly improves computational efficiency, and then dramatically save power and maintenances cost. the actual tests in real seismic data illustrate that high performance computing based on General Purpose GPU technology(GPGPU)is a important direction of developments to meet the requirements of large scale computing in petroleum industry.
