G3i® NXT

Next Generation of Cable Acquisition Systems

G3i® NXT is the latest generation of INOVA’s world class cable acquisition system. It presents an innovative ultra-lightweight design packed with features for optimal efficiency. As the lightest cable acquisition ground electronic on the market, this new system offers seismic contractors and E&P companies a smaller, energy efficient acquisition system that provides real-time data in a robust package.

Built on a field-proven cable architecture and years of G3i® successes, G3i NXT is fully compatible with G3i® HD and provides all the advantages of the G3i technology with over a 50% reduction in weight and 20% reduction in power consumption. Managed by the iX1 control center, it offers key capabilities for efficiency such as high productivity vibroseis (HPVS), dynamic multipath rerouting, HyperSource™ communication, and remote encoder amongst many others.

G3i NXT is the optimal solution for keeping projects rolling in real-time while minimizing operational effort.



iX1

G3i NXT is powered by a robust software called iX1® that consolidates source control and spread management into one simplified view for the Observer. It also enables single command and control over hybrid nodal and cable-based operations with two INOVA systems working together on a survey.

Cable Breaks

Cable Breaks

We’ve engineered G3i NXT to mitigate the risk of data loss by creating multi-path telemetry that reroutes data, in the event of a break, to the nearest Fiber Tap Unit (FTU), a 4-channel ground electronic that connects receiver lines and cross lines.

Exclusions

Exclusions

When exclusion areas, difficult terrain or obstacles prohibit equipment deployment, G3i NXT allows you to keep transmitting data between two sections of the spread by using LaserLink. LaserLink pairs can be attached directly to a Remote Acquisition Module (RAM) ground electronics unit, and will radio communicate within 2km of each other.

HyperSource™

HyperSource™

HyperSource is an innovative approach to overcoming current radio technology limitations and is a new feature available in INOVA’s G3i NXT cable acquisition system with iX1 acquisition software. HyperSource consists of a hybrid, wired and wireless, communication network available for access by distant source crews on a project operating where logistically convenient for efficient production.

Nodal System Integration

Nodal System Integration

Two systems, one dataset -beautiful harmony. Say goodbye to the frustration of managing two recording systems for the same survey. INOVA's G3i NXT is fully integrated so you can deliver one seamless dataset to your clients. The onboard iX1 software in all Inova recording systems allows you to manage the entire spread, and reflects both cable and nodal ground electronics on a single, intuitive display. Observers have full command and control over operations, so they can quickly QC and manage data, sources and spread diagnostics in one location.

Mixed Source

Mixed Source

It’s common to have surveys over a large area where terrain varies and dictates the use of vibs, dynamite and/or airguns. G3i NXT supports all three energy sources and offers an intuitive source QC functionality through the onboard iX1 software.

HPVS Support

HPVS Support

G3i NXT powered by iX1 software supports most high productivity vibroseis survey designs including dynamic slip-sweep, distance separated sweeping (DS3and DS4), independent sweeping (ISS) and HFVS.

Vib Logistics Management

Vib Logistics Management

Running several fleets of vibrators simultaneously over several hundred kilometers of spread poses significant HSE and source management challenges. Being able to visualize the locations of the vibrators on the spread requires onboard navigation systems that communicate directly with the recorder. When working together, vib ops become more efficient and accurate, and Observers gain total control over the survey through a single, intuitive system software, iX1.

Source QC

Source QC

The Source QC module of iX1 uses information contained in the PSS data to provide production statistics and user-friendly production QC visualization. Source QC is excellent tool to monitor vibrator production rates and sweep QC information on a high-productivity vibroseis survey.
