About Geophysical

Stema Systems does your geophysical surveys and has developed a market leading sub-bottom profiling methodology using a combination of uniquely designed equipment with in-house developed Silas software, resulting in a system that can provide a host of sub-bottom analysis results catering to the clients specific needs.
