QUALITY, SAFETY, RELIABILITY

Seismic data processing Having 10 years experience in operations and performing seismic data processing our team delivers high-quality, onshore and offshore, 2D and 3D seismic processing. For the last two years NovaSeis successfully processed nearly 4000 km 2D (9 projects) and 650 km² 3D (4 projects). Many of those projects required a comprehensive approach to solve complicated geological tasks, remove substantial amount of noise and complex statics-velocity issues. For the highest quality time domain seismic data processing we utilize latest software and algorithms. As an addition to these services, we also offer full client support and consultation. Such approach has been successfully implemented during the last few years of cooperation with San Leon Energy. Software packages used by our team of experts are as follows: ProMax/ SeisSpace 2D/3D Landmark software Seismic Studio Sigma Cube software Surfer 10 We have over 80TB of disc space including 12TB ultra fast SSD.
