Geophysical Service Incorporated is a Calgary based company which provides exclusive and non-exclusive 2D and 3D marine seismic data, gravity and magnetic data off the coasts of Nova Scotia, Newfoundland and Labrador, as well as the Arctic Islands, Beaufort Sea, and offshore southern Atlantic.

The company’s fascinating history dates back to its founding in 1930 by John Karcher and Eugene McDermott.

Karcher was an American geophysicist and businessman who invented the reflection seismograph, applying for patents in 1919. He eventually commercialized the process by which most of the world’s oil reserves were discovered. McDermott was a geophysicist and pioneer of providing seismic services to the petroleum industry.

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

The original GSI would later spin off a company known at Texas Instruments in 1950. GSI was bought by Halliburton in 1988.

In 1992, a Canadian, Davey Einarsson who was a long time executive with the “old GSI “and who personally promoted and managed the collection of all of the massive GSI data covering offshore Canada in the 1970’s-1990’s, purchased the proprietary rights to GSI’s speculative data in the Canadian offshore, and formed the “new GSI” in Calgary.

In 1997 Paul Einarsson, an original investor in the firm, joined the company as COO and chairman.
The company also owned and operated the GSI Admiral and the GSI Pacific, the former being the only Canadian flagged seismic vessel operating offshore Canada, including the high Artic, and around the world for years.

GSI is the largest owner of seismic data in Canada. 

“Something no one ever did before!”

Davey Einarsson is a true pioneer in the industry with a legendary reputation for his technical and operational achievements – taking Geophysics where no one had gone before.

During his more than 50 years in the industry Davey was always at the forefront of innovation.

In Canada his work to collect data in the challenging environment of the Canadian Frontier is legendary.

Davey Einarsson is currently the President of GSI.
