Z-Terra is a provider of software and service solutions for the upstream oil and gas industry.
Z-Terra’s software helps oil and gas companies visualize 3-D earth structures and reduce the drilling risk associated with oil and gas exploration from ever more challenging plays. Our vision is to develop the fastest depth processing system in the industry and reduce turnaround time on large seismic projects from 6-8 months to 1 month.
Z-Terra develops a suite of interactive depth imaging and velocity model building software products, designed to be the fastest and most accurate depth imaging solutions. Our processing system is based on a combination of Smart Migrations™, (ultra-fast imaging algorithms that allow for very fast imaging iterations - order of minutes for imaging thousands of square kilometers), combined with very fast migration velocity analysis tools, including wide-azimuth tomography, in a workflow designed to optimally produce the best quality image in the shortest possible amount of time.
One member of the Smart Migrations™ family is the Fast Beam Migration, a super-efficient algorithm that is on average 100 times faster than the industry standard Kirchhoff depth migration.
The Wide Azimuth Tomography using Extended Gathers is a novel innovation in the field of migration velocity analysis. All the imaging and tomographic updates are instrumented to handle VTI and TTI anisotropy.
The award winning Z-Terra development team is experienced in both developing and delivering complex imaging solutions. The team has been involved in pioneering, innovating, developing and using many high-resolution software solutions including 3-D prestack time and depth Kirchhoff migration, 3-D prestack variable azimuth and common azimuth wave-equation migration, wave-equation migration velocity analysis using offset and angle gathers, shot profile wave equation migration, azimuth moveout, wave-equation reverse time migration, wave-field and wave-path tomography. We are also experienced users, we have processed many large seismic surveys from all the major sedimentary basins in the world.
