INOVA Geophysical

IN A CLASS OF ITS OWN.

Scalable cable system for 2D to high -channel Count 3D operations

INOVA introduces the G3i HD, the toughest, most flexible cable-based recording system available today. Built on a field-proven cabled architecture, the system helps E&P companies and seismic contractors overcome their operational challenges whether they are conducting the simplest or the most demanding acquisition programs across the globe. G3i HD can be used with analog geophones or in digital configuration using our single point Accuseis sensor.

In exclusion areas where terrain or regulations prohibit equipment layout, use G3i’s NetLink to transmit point-to-point data wirelessly within 3km. No need to roll the spread or use two recorders; just point and connect -it’s that simple.

The power of iX1, G3i’s intuitive system software, means observers can manage hybrid operations from transition zone to land, or from cabled to nodal systems, without the headache of merging datasets.

Operational Benefits

It’s a mix-and-match kind of world, and seismic is no different. Digital and analog. Nodal and cabled. Transition zone and land. Dynamite and vibroseis or airgun.

These are common combinations during acquisition, but they introduce complexity in recording, QC, data management and operations. We’ve eliminated the frustration of hybrid ops by creating the G3i HD high-capacity, cable-based acquisition system powered by iX1 technology.

Simply put, G3i HD takes the guesswork and headache out of conducting onshore and transition zone surveys.

iX1

Love managing the spread and source QC in two separate systems? Or merging two datasets of varying formats to accommodate mixed nodal and cable acquisitions? We didn’t think so. All Inova recording systems are 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 (G3i HD + Hawk; or G3i HD + Quantum).

Cable Breaks

We’ve engineered G3i HD 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 unit that connects receiver lines and cross lines. Additionally, all ground electronics are equipped with LED indicators that display connectivity, power and telemetry status so you can quickly troubleshoot unit(s) that need to be addressed.

Dead Zones

Can you hear me now? When operating in dense canopy, mountainous regions and dead zones, radio communications are often non-existent. G3i HD offers a workaround for crews using Shot Pro II or Shot Pro HD controllers. Dynamite crews can continue to operate through wireline shooting whereby they simply connect the Shot Pro HD Encoder to the nearest G3i HD ground equipment and can immediately transmit data again.

Exclusions

When exclusion areas, difficult terrain or obstacles prohibit equipment deployment, G3i HD allows you to keep transmitting data between two sections of the spread by using NetLink. NetLink pairs can be attached directly to a Remote Acquisition Module (RAM) ground electronics unit, and will radio communicate within 3km of each other.

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 HD and Hawk are fully integrated so you can deliver one seamless dataset to your clients. The onboardiX1 software in all Inova recording systems allows you to manage the entire spread, and reflects both cable and nodal ground units 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.

Transition Zone Surveys

Meet our alter ego. G3i HD TZ is one of the only onshore cable-based recording systems that can double as a transition zone acquisition system. By simply using our specially designed waterproof electronics, and a casing (TZ sleeve) for standard RAM ground electronics, crews can easily convert an onshore acquisition into a hybrid operation in up to 125m depth of fresh or saltwater. Full support of airguns, a stronger TZ cable and watertight connectors are just a few of the features G3i HD TZ offers.

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 HD supports all three energy sources and offers an intuitive source QC functionality through the onboard iX1 software.

HPVS Support

G3i HD 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

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. INOVA vibrators can be outfitted with Connex Vib and Vib Pro HD which are fully integrated and supported in the G3i HD central 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

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.

HyperSource

HyperSourceTM is an innovative approach to overcoming current radio technology limitations and is a new feature available in INOVA’s G3i HD 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. In a high productivity vibroseis example this might consist of multiple vibroseis fleets operating within or even beyond the perimeter of the active patch spanning 10’s of kilometers from the recording truck.
