Sigma: Cableless Seismic Acquisition System

Product Details : 

iSeis

The International Seismic Corporation was formed to deliver hybrid cableless recording hardware which suffered none of the drawbacks of other systems. Sigma™ solves specific problems identified with earlier technology and takes the exploration industry into a far more flexible future.

Sigma™

Sigma™ is the most advanced, field-proven cableless acquisition system. It is a multi-mode stand alone recorder and also can be used side-by-side existing cabled hardware. It works seamlessly with Seismic Source Co, products and other controllers to provide the most fully integrated source control/recorder solution. It has already set records in passive as well as active acquisition.

Seismic Source Co

Seismic Source Co is iSeis’s sister company. Based in Ponca City, the home of vibroseis, SSC has a long history of providing peripheral equipment to the land exploration industry including sophisticated vibroseis/impulsive source controllers. SSC is the world's largest independent vibroseis R&D center, developing a variety of test and QC products. iSeis and SSC products can be used separately or combined to provide the most sophisticated range of land seismic equipment anywhere.
