Our products and services are intended to measure and interpret seismic data about rock and fluid properties within the Earth�s subsurface to enable oil and gas companies to make improved drilling and production decisions. We also acquire and process seismic data from seismic surveys in regional data programs, which then become part of our seismic data library.
