"First recommended in September 2004, Helix Energy Solutions (NYSE: HLX) is the oldest holding on our Buy List - and the biggest winner, gaining 133%," notes Richard Moroney.

Here, the editor of Upside explain, "Considering its bright profit-growth prospects, reasonable valuation, and impressive Quadrix scores, Helix remains among our very best ideas and a top pick in the oil patch."

"Helix serves energy producers worldwide, providing such contract services (36% of total revenue for the nine months ended September) as deepwater pipe-laying, well operations, robotics, and reservoir services.

"The shelf-contracting business (34%) consists of 59%-owned Cal Dive International (NYSE: DVR), a provider of dive-related and shallow-water construction services.

"The fast-growing oil and natural gas production business (30%) focuses on marginal, mature, and smaller fields - properties no longer significant or viable for large energy companies. Fueled partly by high energy prices, petroleum companies are increasingly targeting mature and small reservoirs.
