Seismic illumination and RTM PSDM. Regional Gulf of Mexico model.
In the current environment of low oil prices, oil companies are seeking ways to reduce exploration and development costs. The highest cost in exploration for new oil and gas reservoirs and development of discovered fields is in well drilling. Having better and more accurate seismic data reduces the cost of well drilling, resulting with a lower cost in producing oil and gas. This will enable producers to operate in the current market.
A key recent development in seismic imaging that is helping the industry to obtain more accurate seismic data is the application of depth imaging based on ‘Reverse Time Migration’ prestack depth migration (RTM PSDM) algorithms. This unique algorithm was introduced to the industry more than 30 years ago but became operational only in the past several years due to the recent developments in computer hardware technology.
RTM PSDM has been proven to provide the seismic data quality that the oil and gas industry desires. However, due to computational costs, it still proved too costly to use the full frequency of the seismic data when using the algorithm. This led to depth-migrated seismic data that did not present the optimal fidelity of the seismic data which, in turn, resulted in less accurate interpretations of the data.
In order to provide a solution to the industry, SeismicCity has developed a new mathematical formulation enabling high frequency application of RTM PSDM in an industrial setting.
