Seismic Technology
Scalable | Tailored | Low-impact | High-energy | Innovative
At Oceania Geo, we’re driving the future of seismic acquisition innovation with cutting-edge technology and our commitment to research and development. ​Our unique specialised equipment and methodologies have an extremely low impact on the environment, whilst maintaining personnel safety, lower costs and data integrity. Custom-made seismic sources that are scalable and tailored to each project, combine with lightweight geophysical receivers to achieve high productivity outputs from our crew.
​
AF750
The AF750 packs a punch while upholding a remarkably low footprint!
It combines over 40,000lbs of hold down force and up to 55kJ of impact energy, powered by a 375kg weight and dual nitrogen springs. Despite its impressive power, the AF750 exerts minimal environmental impact, with less than 6psi of ground pressure during travel.
Ideal for remote landscapes and tackling the challenges of the Australian terrain, the AF750 has proven results in imaging depths greater than 4kms, and examples from New Zealand reaching over 5kms.
WD1000
The WD1000 is a gravity based weight drop, custom designed and built by Oceania Geo. Featuring a scalable 1000kg to 1400kg hammer, dropped from a height of up to 2.7m, it achieves approximately 25000J of impact energy (based on the 1000KG hammer).
This piece of equipment has been specifically designed to be scalable and adaptable, ensuring compatibility with a range of carrier options including tractors, skid steers, telehandlers, and front-end loaders. Its portability allows for easy mobilisation on a trailer behind a ute, minimising mobilisation costs and providing flexibility in the field.
The WD1000 has a proven track record of achieving imaging depths to approximately 3km and it has enabled very low footprint seismic acquisition in some of Australia's most remote areas.
GPEG-500
The GPEG-500 or "The Thumper" as we have always called it, is a lightweight, all-terrain, 500kg gravity based weight drop that delivers 5kJ of impact energy, making it ideal for imaging shallow to mid-range target depths (30-1000m).
The GPEG-500 is able to access hard to reach locations with ease, as it has many carrier options; from remote controlled skid steers to posi-tracks, tractors to front-end loaders.
We are continuously reviewing, evaluating and enhancing how the GPEG-500 functions, as well as optimising the choice of carrier for any given terrain to minimise our environmental footprint and eliminate any line-preparation.
AWD-60
The AWD-60, is our "little thumper" affectionately nicknamed Bambi.
Bambi is a bespoke accelerated weight drop with an impact energy of 1000-2500J.
Custom designed by Oceania Geo, Bambi provides us a scalable, lighter option for use on multiple small agile carriers to target shallow imaging.
As with all our sources, Bambi is consistently tested and adjusted to ensure we are producing the best possible data results whilst improving efficiency and productivity.
Dynamite
Dynamite is the preferred seismic source in some terrain, where other source options cannot safely traverse, there are environmental access constraints, or the geology is better suited to a buried source.
Providing a sharp pulse and broader bandwidth than weight-drop seismic sources or vibroseis, dynamite is ideal for exploring greater depths and capturing data over larger distances.
​
Dynamite generates a highly-controlled, consistent and powerful source of energy that generates strong seismic waves beneath the Earth.
A large range of charge sizes can be utilised to target specific depths of interest.
Nodal Receivers
Oceania Geo deploys predominantly Stryde nodes. These smaller, lighter, and cheaper receivers have transformed both the design philosophy and operational execution​ of seismic acquisition.
​
​Key features of the Stryde node, when combined with Oceania Geo's source fleet:
-
Fully autonomous broadband accelerometers 1-125Hz​​
-
45 days of 12hr recording​​
-
300-1600+ deployed crew/day depending on spacing/terrain​​
-
All hand carry – one person can carry up to 90 nodes​​
-
Scalable – 1000 to 50,000+ with little variation in ancillary equipment​​
-
Near perfect coupling when deployed appropriately for terrain​
