SeismicCity is an industry leader in providing depth imaging services. We are dedicated to the development and application of the newest technologies. Our services combined with proprietary algorithms developed on top of commercial software, provide the best available solutions in the field of depth imaging. We consistently execute model building, interpretation, prestack depth migration and simulation projects to the highest industry standards. SeismicCity’s prestack depth migration algorithms are developed for multi-core massively parallel computers that include the newest in computer hardware technology, the hybrid CPU / GPU computer clusters. These modern supercomputers are configured and optimized for processing large seismic datasets. With a unique set of prestack depth migration algorithms, a highly experienced staff dedicated to model building and depth imaging, and large computer configuration, we are able to construct the most reliable prestack depth migrated volumes. SeismicCity’s depth imaging products are commonly used in the planning and execution of complex exploration program.

History
SeismicCity was established in early 2000 as a company dedicated to the development and implementation of depth imaging technology. The company‘s mission is to construct and deliver the most reliable depth migrated volumes for oil and gas exploration companies. SeismicCity is routinely executing numerous complex depth imaging projects that are being used by their clients for successful exploration programs in many geographical regions.

Our Focus
Our main focus is the execution of depth imaging projects. This involves preprocessing of time domain data, construction of interval velocity models, and application of prestack depth migration. To assist in model building, our workflows involve the use of simulations to aid in correct interpretation migrated field data. In order to provide the most reliable prestack depth migrated volumes, we are providing full anisotropic (VTI and TTI) model building and depth imaging.

Implementation
For constructing the best depth migrated volumes we are employing several depth migration algorithms. These include a wavefront reconstruction based Kirchhoff summation algorithm, a one way downward extrapolation wave equation algorithm, and a two way Reverse Time Migration algorithm (“RTM”). All of our prestack depth migration algorithms are implemented in the common shot domain, enabling their use for narrow azimuth, multi azimuth and wide azimuth surveys.

What we offer

SeismicCity’s prestack depth migration algorithms are developed in house by our research and development staff. The prestack depth migration algorithms are developed on top of commercial software used for preprocessing, interpretation and modeling. Our prestack depth migration algorithms are optimized to take full advantage of evolving computer hardware. An integral part of our development effort is the incorporation of the newest computer technology built specifically for storage and processing of large seismic datasets. In the past few years we have upgraded our hardware configuration to the newly developed hybrid computer clusters which are using a combination of both CPU and GPU technology. This delivers a dramatic throughput increase over the CPU only configuration. With this new installation we are able to offer the application of common shot Reverse Time Migration as a key component of our services.
