Seismic Data is acquired on land and in marine environment to find out the location of oil & gas reservoir in the subsurface. The processing of seismic data involves several steps before it gets converted into a meaningful and interpretable image of earth volume. Seismic Imaging is an advance processing step which converts seismic data to an earth subsurface image. Seismic imaging aims to create high resolution 2D & 3D structural images of subsurface geology. Reverse Time Migration (RTM) is one of the most reliable and preferred solution for seismic imaging of geological subsurface with complex structures. It can handle large velocity variation without any dip limitations for producing the earth subsurface structure with high resolution. It can deliver subsurface images with high accuracy in different mediums. RTM is highly computation, I/O and storage intensive, which requires High Performance Computing (HPC) ecosystem for execution.

 

Under the National Supercomputing Mission (NSM), “A HPC software suite for seismic imaging to aid oil and gas exploration” is a “Make in India” initiative to develop a customizable and efficient RTM software “SeisRTM”. It can provide high-resolution 2D & 3D seismic images of complex geological subsurface using acquired large seismic data. This software provides 2D modelling and RTM capabilities for both isotropic and anisotropic (VTI and TTI) media, as well as 3D isotropic modelling and RTM. SeisRTM is equipped with a suite of data preparation and post-processing tools, optimized to handle high-frequency migration and large datasets efficiently. It is designed for parallel computing environments, making it well-suited for deployment on CPU clusters without core limitations. SeisRTM offers both a Command Line Interface (CLI) and a Graphical User Interface (GUI) for user flexibility and includes an in-house developed data visualization tool to streamline data analysis and visualization. The indigenously developed “SeisRTM,” built on NSM infrastructure, will serve as a seismic imaging facility, delivering 3D RTM capabilities for upstream oil and gas exploration companies in India.
