Energy stocks in Oslo took a hit Monday, the first business day back in Western countries after Opec’s decision to cut oil production failed to trigger a corresponding oil-price spike Monday, and instead oil fell to below $62 a barrel.

Calgary-based but Oslo-listed Artumas fell most at 28.57 percent, as the market saw farm-in discussions as a sign of cash shortage ahead of a project to monetize more of its Tanzanian gas. Aker Solutions, down over 10 percent, led a 6.34 percent slide in oil-focused Oslo that saw related outfits BW Gas lose 19.52 percent, CanArgo slip over 16 percent and DOF Subsea fall 12.28 percent.

Bright spots in Oslo included Noreco (up 19.44 percent), Revus (up over 100 percent on its sale to Wintershall) and offshore shipper Farstad up nearly 10 percent.
