Seismic Reflection and Refraction Surveys
Seismic Survey Equipment
We have New Zealand’s most extensive range of shallow seismic survey equipment with 144 channel capability. With a large range of geophones and sources we can undertake surveys in almost any environment. Since developing the first land streamer seismic system in New Zealand in 2004, the company has developed a full range of systems for rapid and cost-effective surveying.
We have standard seismic reflection and refraction equipment. In addition, we have the following equipment:
A trailer mounted 50kg accelerated weight drop with a depth capability of 500-750m.
Marsh geophones for transition/underwater zone surveys.
Radio trigger system allowing a distributed system in the urban environment.
Shear wave land sources and geophones.
Underwater shear wave source for shallow marine downhole/CPT shear wave testing from barges and wharfs.
