In 1992, Davey Einarsson, a longtime executive of the original GSI, purchased the proprietary rights to GSI’s speculative data in the Canadian offshore, launching the new GSI in Calgary. Paul Einarsson is the COO and Chairman of Geophysical Service Incorporated. He joined the company in 1997. GSI is the largest owner of marine seismic data in Canada, with its head office located in Calgary, Alberta. Recent developments: GSI is currently involved in several cases of litigation for damages over disclosure of its confidential seismic data. The court challenges include litigation with the Canada-Newfoundland Offshore Petroleum Board, the Canada-Nova Scotia Offshore Petroleum Board and companies that have obtained GSI data from a third party or government.
