Why Investors Backed GTI
GTI combines proprietary seismic hardware with manufacturing and field-service capabilities. Its NuSeis systems cover land, transition-zone and shallow-water work. Global Geophysical Services gives the company an affiliated operator for projects. A four-year collaboration with TGS extends that offer into deep water.
The problem it targets
Seismic crews must place, locate, monitor and recover large numbers of sensors across difficult terrain. GTI's view is that separate surveying, exposed equipment and weak field status data add labor, vehicle use and avoidable data loss.
What the product does
NuSeis nodes record seismic data and calculate their own position from satellite signals. The system reports device health in the field and supports different sensors, housings and deployment methods. GTI sells, leases and customizes the equipment.
Progress so far
GTI customers have recorded less than 1% data loss on surveys. Global Geophysical Services says its GTI partnership provides access to more than 330,000 NuSeis channels across land, transition-zone and ocean-bottom configurations.
Who backs it
Employees, directors and high-net-worth individuals own GTI. It does not publicly identify the individual investors or announce the private offerings.
How the market is moving
In August 2026, TGS and GTI announced a four-year framework for joint shallow-water, transition-zone and deepwater projects. TGS contributes deepwater vessels and ocean-bottom nodes, while GTI contributes NuSeis hardware, manufacturing and shallow-water experience.
