Abstract

Obtaining high-resolution images of the underground geological structures using seismic reflection data in prestack or poststack domain is crucial for exploration of oil and gas deposits. In petroleum industry, seismic migration is one of the most compute intensive steps in seismic data processing sequence. It accurately images the reflected and diffracted energy and aids in delineating the structural features of the underground geological formations. Migration techniques are highly compute and input/output (I/O) intensive and therefore requires high performance computing. In the last decade the development of parallel distributed computing platforms, related system software and programming environments have made it possible to use parallel codes for high resolution imaging. Centre for Development of Advanced Computing (C-DAC), Pune has developed the OpenFrame architecture for scalable parallel computing applications. Various seismic migration algorithms have been developed and implemented for imaging purposes. In this presentation we will discuss the parallel implementation achieved on C-DAC
