Readers of this space know that one of the preferred sectors is the oil/oil services sector, and with the above in mind, Canadian Natural Resources is worth an evaluation.

Canadian Natural Resource Ltd. (NYSE: CNQ) is a Canada-based exploration and production company that explores for, develops, produces, markets and sells crude oil, natural gas liquids and natural gas.

Analysts like CNQ projected double-digit revenue for FY 2009, following a solid performance in FY 2008. Further, analysts still see impressive margins from CNQ's Canadian oil sands operations, despite the province of Alberta's oil/gas royalties increases. CNQ is also one of the largest undeveloped land holders in the Western Canadian Sedimentary Basin, with nearly 12.8 million acres. The company also has proved reserves of 1.3 billion barrels of oil and 3.8 trillion cubic feet of natural gas.

In his Block Trader Oil & Gas, Peter Way follows the big hedge funds and market makers to find out what they are doing. Here's a look at his top oil plays.

He observes, "The hedgers at the NYMEX are protecting their crude oil positions in ways that indicate they see continuing upward pressure on prices."

Based on this hedging activity, he states, "The outlook for the next 12 expiration months that the by major players at the crude oil table suggest little lasting price weakness, and a general level prevailing above $70 over the remainder of the year."

What are the best stocks to buy to bet on the trend for firm oil prices? To decide, Peter Way looks at the buying patterns of market makers -- the big boys on the trading floor.

From their positions, he notes, "Among the large oil producers, China's CNOOC, Ltd. (NYSE: CEO), Canadian Natural Resources, Ltd. (NYSE: CNQ), and Suncor Energy (NYSE: SU) all combine historically strong odds and payoffs."

In addition, he notes positive market maker activity among oil exploration & production stocks. He explains, "With significant quantities of low-cost reserves already found, and prospects for additional finds tied up, these companies inevitably will get acquired by bigger producers whose customer demands exceed their yearly reserve findings."

For many, he says, it's just a matter of time. Notable stocks in the stock, he adds, are Holly Corp. (NYSE: HOC), Carrizo Oil & Gas (NASDAQ: CRZO), Range Resources (NYSE: RRC), Southwest Energy (NYSE: SWN), Ultra Petroleum (NYSE: UPL), and Talisman Energy (NYSE: TLM).
