Paradigm reports industrial-strength use of the computationally intense technique of reverse time migration using code running on high performance graphics processing units (GPU) from Nvidia Corp. Reverse time migration (RTM) is a preferred solution for imaging complex structures such as are encountered in the deepwater Gulf of Mexico. RTM (actually a depth imaging solution) code has been around for a while, but it is only in the last few years that computing power has been capable of imaging large 3D data sets.
Acceleware’s RTM library leverages Nvidia’s CUDA compiler that allows the same code to run on either GPUs or CPUs as appropriate. The Echos RTM module supports anisotropic imaging. The code can be run in ‘modeling’ mode, to generate synthetic shot records and coupled with Paradigm’s ‘Skua’ interpretation flagship. More from www.oilit.com/links/1103_33.
