SeismicCity ADVANTAGE

depth imaging projectSeismicCity's advantage is in its expertise of depth imaging technology and services and the company’s ability to adopt new technologies quickly. We offer a combination of unique proprietary depth imaging technology coupled with outstanding experience in execution of depth imaging projects. We are routinely constructing accurate depth imaging volumes that are directly used in the positioning of new well locations.

SeismicCity is focused on depth imaging technology. This involves constant development and upgrading of our tools and algorithms. Depth imaging technology is an evolving technology and we are dedicated to the development and modifications of our tools. This gives us the ability to offer execution of the most complex depth imaging projects, helping our clients execute complex exploration programs.

The latest new technology offered by SeismicCity is TTI Reverse Time Migration (“TTI RTM”).  With the new marine seismic data recorded in the past several years, much more reliable anisotropic models can be constructed for application of prestack depth migration. Having more accurate anisotropic models, TTI RTM became a practical prestack depth migration algorithm that can be offered as a routine depth imaging tool.

In the past few years anisotropic RTM has been the focus of our development. This included optimization of the two-way wave propagation algorithms to include high order finite differences operators and update to use of TTI anisotropic wave equations. The high computational cost of TTI RTM was addressed by an upgrade of our hardware platform from CPU based to hybrid CPU/GPU based computer clusters. This involved the optimization of our RTM prestack depth migration software to take advantage of the high computational power of GPU technology. This change put SeismicCity at the forefront of production implementation of TTI RTM technology on GPU technology. Read More

In order to qualify model building techniques as well as new depth imaging algorithms, SeismicCity participated in the creation, simulation and imaging of the Gulf of Mexico (GOM) Tempest model, dataset and prestack depth migration. The anisotropic Tempest model and dataset is a unique anisotropic wide azimuth (WAZ) dataset which is being used by leading exploration companies to qualify new depth imaging techniques currently used in new deep water GOM projects.

These include new methods for mutiples removal, new prestack depth migration algorithms, and new methods for anisotropic velocity model building. Anisotropic model building is a routine procedure used in construction of velocity models used for depth imaging, and having a simulated dataset with a known model can guide the users of the Tempest dataset to the way for correctly finding the true anisotropic parameters and model.
