INOVA unveils new cable-based seismic survey system

INOVA_systemINOVA Geophysical announced the release of G3i, a flexible and rugged mega channel land recording system.

Portable technology

The system offers the industry a 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.

Cable-based recording system

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, powerdown- the-line (PDL) technology and high productivity vibroseis (HPVS) capabilities.

Higher rate of return

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.

Key features

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.

Driven by customer needs

Mr. Glenn Hauer, Senior Vice President of Product Management stated, "The technology advancements we've made to this system have been widely driven by our customer needs in the field. For High Productivity Vibroseis operations, we knew our customers needed a high capacity system using powerdown- the-line technology to help reduce battery dependency, and with less equipment to transport, crews can work more efficiently during high channel count acquisition."

Reduced operational costs

"We designed a system that would provide all of this, plus the ability to perform in-field maintenance to the ground electronics quickly and with minimal system downtime; this helps reduce overall operational costs."

G3i was initially field tested in November of 2011 and later in February of this year for High Productivity Vibroseis techniques in an oil field in Western China by BGP.
