Mathematicians and geophysicists at Moscow State University have presented a revolutionary method for three-dimensional seismic modeling, performed on the "MSU-270" supercomputer. The technology allows data to be processed 3 times faster than traditional approaches, which is critical for the search for hard-to-recover oil reserves in the Arctic and Western Siberia.
Unlike ray tracing, the full-wave method takes into account all types of seismic waves, including longitudinal, transverse, and surface waves. This method reduces the risk of errors in data interpretation, which previously led to ineffective drilling. To simulate real seismic exploration, it was necessary to conduct 12,000 calculations, which became possible thanks to a new module developed jointly with Fidesys.
The computing resources of "MSU-270" made it possible to perform three-dimensional calculations in two months. This is a world record for detailed models of Western Siberia.
The new MSU approach may change the standards of seismic exploration: reducing calculation times from months to weeks will reduce the cost of field exploration. Similar technologies, such as Schlumberger and Halliburton algorithms, are still inferior in accuracy when working with 3D models. The introduction of the development into the industry will accelerate the development of Arctic regions, where exploration errors are especially costly.
