Electromagnetic Geoservices (EMGS) has sealed a final contract for a multi-client survey in the Norwegian Barents Sea, under the letter of intent (LOI) signed in March.

The scope of the LOI has been extended since it was first signed last month, which has increased the contract's value to $3.4m from the previous $2.5m.

The deal was signed by Spirit Energy Norway on behalf of the PL1031 production license group, which operate a block in the Barents Sea on the Norwegian Continental Shelf.
