Norwegian geophysical services company Electromagnetic Geoservices ASA (EMGS) on Monday announced it secured $2 million in prefunding for a multi-client survey offshore Newfoundland and Labrador.The acquisition is expected to take place in late third quarter 2022, EMGS said, noting the contract is conditional upon securing the required permits in Canada prior to September 2022.The said it expects to recognize the revenue in the fourth quarter of this year.

OFG, EMGS Enter Cooperation Agreement

Ocean Floor Geophysics Inc (OFG) and Electromagnetic Geoservices ASA (EMGS) signed a cooperation agreement under which the two companies agree to work together on various projects to promote the use of marine CSEM technology.The agreement places specific emphasis on exploiting the obvious synergies between the state-of-the-art towed-streamer CSEM system from OFG (under its exclusive right to acquire the PGS EM technology) and the industry-leading sea-bottom CSEM/MT nodal system from EMGS. Cooperation will include development of proprietary and multi-client surveys, and multiphysics reprocessing of
