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.

Positions on each of the Vibrators are calculated with a Novatel ProPack V3 OmniStar DGPS receiver, which is providing decimeter accuracy. The whole system is capable to operate as a hand-free source driven recording system, which provides higher daily production than a traditional source controlled systems.
Vibrator QC The vibrator crew utilizes Seismic Source BirdDog II Vibrator QC System as a tool to manage /QC vibrator output. NovaSeis provides a variety of configurations and a comprehensive selection of source energy to accommodate any terrain. The use of multiple energy sources and receiver types minimizes environmental impact on complex projects.
Recording system Cable-free Technology. The latest wireless OYO Geospace Seismic Recorder (GSR) system. GSR is the unique system for high-quality, precision to capture 2D, 3D, and 4D seismic data in a variety of environments and terrains in order to attain high production rates and deliver premier image results. Cable-free acquisition technology provides access in areas where cable-based systems are unworkable. System specification in brief: • • • •
unlimited channel capabilities designed for autonomous seismic data recording each GSR unit includes 1 channel of 24-bit digitization and is capable of up to 30 days of continuous recording with standard 2ms sample rate, and a high-speed data port for data downloading. The units are kept in a sealed case, with input connector, extended life battery connector/data port connector the line equipment is checked daily (quality control) via handheld Trimble Yuma units, which wirelessly acquires and downloads the tests. Anything outside limitation threshold is indicated and rectified compatible with explosive, vibratory and impulsive energy sources
Our recent recording operations proved that acquisition rates are greatly improved comparing to traditional methods. This maximizes our exploration budgets whilst keeping high quality of data best practice. NovaSeis has been set-up to provide a state of the art acquisition system in all sorts of terrain, thus achieving cost effective and minimal environmental impact on projects.
