Client-driven subsurface data acquisition technology
Allton’s innovative Nautilus System provides cost-effective deployment and recovery of seismic OBN
Allton is a Geophysical Technology and Service company that specialises in seismic data acquisition. Our focus is on cost-efficient solutions for node deployment and recovery in shallow to deep water marine environments.
The Company has a long track record of operating node receivers for subsurface hydrocarbon exploration from the Controlled Source Electromagnetic (CSEM) segment.
Allton has offices in Stavanger and Oslo.
Nautilus Seismic OBN Acquisition = Cost Reductions + Time Savings + Lower Carbon Footprint
Successful Sognefjord Test of Allton's Nautilus Seismic OBN System
Allton has conducted successful tests of its latest iteration of the Nautilus Drop & Pop standalone seismic OBN vehicle.
In June 2025, Allton successfully conducted tests of the latest iteration of its seismic OBN Drop & Pop vehicle in both shallow and deep water environments at Sognefjord. The survey was conducted using GeoSpace’s Mariner (shallow ¬100m depth) and OBX2-125 (¬1200m depth).
The ROV-free solution was successfully deployed and recovered, and positioning accuracy was ~1% of the planned drop locations.
Allton is now in the commercialisation phase after these latest tests and the successful operational field survey in September 2024. The equipment is being further fine-tuned and commercial acquisition services will be available starting in 2026.
The seismic OBN deployment and recovery solutions have been designed for cost-effective acquisition targeting sparse node velocity surveys and monitoring of satellite fields. The solution can be mobilised on standard platform supply vessels for deployment and recovery at speed.

Successful North Sea Test of Allton's Nautilus Seismic OBN Drop & Pop Vehicle and Multiphysics (MAP) Nodes
Allton has conducted a successful operational field test survey of both its disruptive data acquisition technologies : the Nautilus Drop & Pop standalone seismic OBN vehicle and the Multiphysics Acquisition Platform (MAP) node.
In late September 2024, Allton successfully conducted an operational field test survey of its seismic OBN Drop & Pop vehicles and the MAP nodes (EM + seismic OBN) data acquisition. The survey was conducted in cooperation with a North Sea operator and Seisnode.
Both ROV-free solutions were successfully deployed and recovered, and data logging of both seismic and EM data performed effectively, thereby achieving the goals of the pilot test.
The seismic data from the Seisnode OBNs was logged successfully for all the nodes demonstrating good coupling to the seafloor using Allton’s Drop & Pop acquisition technology. Good quality EM and seismic data were also logged successfully from the MAP nodes.
The equipment is being fine-tuned, with additional fjord and field tests planned for 2025.

ENVIRONMENT
Use of Allton’s technology can reduce GHG emissions in the oil and gas exploration cycles, thereby playing an important role in lower carbon emission ambitions.
SAVE COSTS
The Nautilus System offers cost-savings with fewer moving parts, reduction in operational time and low-cost vessel operations.
HIGHER RETURNS
Our technology solutions will improve return on investment by shortening the cycle time from exploration to 4D production monitoring of small to medium-sized fields.
