A LEGENDARY NAME...A RESPECTED REPUTATION

The original GSI was founded in 1930 to offer the first ever reflection seismograph exploration service to the oil industry. 

In 1992 Davey Einarsson, an industry veteran and executive with the “old GSI,” took ownership of the company and formed the "new" GSI.

GSI is a fully integrated geophysical service company providing exclusive and non-exclusive 2D and 3D marine seismic, gravity, and magnetic data offshore Canada and around the world.  GSI also provides state of the art seismic data processing, depth imaging, and reservoir services.  

GSI's head office is located in Calgary, Alberta, with additional office located in Houston, Texas.
