March 5, 2012 /PRNewswire/ -- INOVA Geophysical announced today the release of G3i™, a highly flexible and rugged land recording system. The mega channel recording system offers the industry a highly-portable technology that provides support for conducting a wide range of land seismic surveys, including high density wide azimuth acquisition for the world's most challenging environments.
Based on years of product development experience in seismic acquisition technologies, INOVA has developed a powerful, cable-based recording system that offers advanced ground electronics, power-down-the-line (PDL) technology and high productivity vibroseis (HPVS) capabilities. G3i supports over 100,000 channels and can be used to capture 2D, high density 3D and time-lapse 4D data. The addition of this new cabled land system will offer seismic players in the industry another alternative for cable-based recording that meets a broad scope of operational demands, allowing contractors to achieve a higher rate of return on their assets.
Several key features provide immense benefit to geophysical contractors, including its rugged, aircraft grade aluminum enclosure and high-strength polycarbonate exterior for maximum durability. Power management and deployment logistics are simplified because the G3i system utilizes PDL technology to evenly distribute battery power to multiple field station units using the power supply (PSU) and fiber tap (FTU) units along with standard 12V batteries. In addition, G3i's ground electronics consume only 235mW of power per channel measured at PSU.
G3i was also designed with the "do more with less" philosophy in mind; contractors can take advantage of having four analog channels in a 1.2 kg compact, remote acquisition module (RAM) station, as opposed to using the existing single channel stations offered by competitors. With less field equipment to transport, maintain, and troubleshoot, surveys can be operated more efficiently.
G3i was initially field tested in November of 2011 and later in February of this year for High Productivity Vibroseis techniques in an oilfield in western China by BGP, the largest land geophysical contractor in the world. Both tests met BGP's high standards of excellence.
