the globe and mail had a lot on take-overs , mergers of junior oil and gas companys that stated ; the prices for acquisitions are dramatically different today, the going rate was around $60,000 per flowing barrel a day of output, while some strong assets are still worth that much, other assets would now likely be priced at only about $35,000. these examples are of course- land based operations, I would hazzard a guess that given the offshore inherent dangers -that would place proven production, and resources in place to be in the higher range. hope this helps ,
