"The oil-services sector remains my favorite long-term play in the energy industry," says sector specialist Elliott Gue. In The Energy Strategist, the advisor looks to industry-leader Schlumberger (NYSE: SLB).

Gue explains, "Oil services firms will benefit directly from the increasing technical complexity of oilfield development. International business is the primary driver for Schlumberger, which generated only 22% of its revenues from North America in 2008.

"The important question is, where do we sit in the cycle for international operations? In my view, the second half of 2010 will mark the beginning of a new uptrend.

"Over the next five years the energy patch should offer some of the best investments around, and one standout is Schlumberger (NYSE: SLB)," says Stephen Leeb in The Complete Investor.

"Schlumberger, by a wide margin, is the best and most dominant. Its services range from well testing to pressure pumping to seismic testing, and it's No. 1 in virtually every area it occupies.

"Some of its operations, especially those that maintain the health of existing wells, are highly recession-resistant.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

"Many experts believe that oil prices are at unsustainably low prices now, and they expect a sharp rise in the commodity price as supply and demand come back into line again," says turnaround expert George Putnam.

In The Turnaround Letter, he suggests, "If oil does begin to rise again, the oilfield service stocks could rebound sharply." Here, he takes a look at large cap plays on a rebound within the oilfield services sector.

"We all know that oil prices have fallen dramatically from their highs in the summer of 2008. But different types of oil-related stocks have reacted quite differently to the price change in the underlying commodity.

"For example, while oil itself has dropped nearly 70% from its 12-month high, the stock of the largest integrated oil company, Exxon-Mobil (NYSE: XOM), is down only 26%, less than the stock market as a whole.

"Long term, supply remains the key issue to watch in the crude oil market; depressed prices continue to force producers to scale back on exploration and development spending," says energy expert Elliott Gue.

In The Energy Strategist, he says, "I watch oil service giant Schlumberger (NYSE: SLB) as a gauge of overall health in energy markets; it has its hands in just about every imaginable oil- or gas-producing market on the planet."

"Schlumberger's fourth quarter earnings release and conference call were far and away the most bearish from the company in at least five years.

"CEO Andrew Gould was notably downbeat, particularly during the analysts' question and answer (Q&A) session. Predictably, earnings estimates have plummeted since that call.

I think it's fair to say that there's much trepidation about the earnings season that picks up steam this week. And for better or worse, numbers from the big financials have begun to roll in. Last week we saw profit sink for JPMorgan Chase (NYSE: JPM) and significant losses from Bank of American Corp. (NYSE: BAC), Citigroup Inc. (NYSE: C), and Deutsche Bank (NYSE: DB).

Analysts surveyed by Thomson Reuters expect Bank of New York Mellon Corp. (NYSE: BK) to be among those financials reporting fourth-quarter earnings growth this week.

Revenue is expected come to $3.8 billion, about the same as it was a year ago. Bank of New York has fallen short of earnings estimates in two of the past five quarters, by as much as 11.1%. For the full year, analysts are looking for $2.78 per share (+5.8%) on $14.8 billion (+4.2%). The consensus recommendation of analysts is to buy BK, and the long-term EPS growth rate forecast is 10.7%. Shares are 48.7% lower than a year ago. Other financials expected to report quarterly earnings growth this week include SunTrust Banks Inc. (NYSE: STI) and M&T Bank Corp. (NYSE: MTB).

"In recoveries from panic selloffs in the past, the energy patch has tended to outperform the S&P 500," notes energy sector specialist Elliott Gue.

In his The Energy Strategist, the advisor offers his outlook for the sector as well as a package of five favorite energy-related stocks, including ideas in the drilling, infrastructure. oil services and exploration areas.

"This has undoubtedly been the most challenging and unsettled market in recent history for the stock, bond, currency and credit markets. Not surprisingly, the energy sector hasn't been immune to the selling pressure.

"However, I would note that the selloff in most energy stocks I cover has little or nothing to do with fundamentals and everything to do with market sentiment and a pervasive sense of panic.

"Institutions are dumping stocks to raise cash and the primary fear infecting the energy markets is that a dramatic global economic slowdown coupled with a seizing up of credit markets will destroy demand for energy commodities..

The need for oil drilling services will continue even if the price of oil declines, according to Richard Lehmann. Here, in his The ETF Investor, he looks at a favorite way for investors to play this trend.

"Oil prices have a triple or quadruple price boost associated with them. The first is supply/demand dynamics, the second is the weak dollar, the third is speculative fervor and the fourth inflation fears.

"A pundit said that last year it took 65 Euros to buy a barrel of oil and today it still takes 65 Euros to buy a barrel of oil. This illustrates the effect the weak dollar is having on U.S. prices and the international price of oil.

"Inflation protection used to be the province of gold, but now it seems oil is serving a similar function. We think the current oil bubble has not run its course.

"One of our past recommendations, the Oil Service Holders Trust (NYSE: OIH), was first suggested in February 2006 at a price of $101.50. We recommended it again in December 2007 at a price of $179.83.

With the economy facing soaring crude oil prices for the past year, consumers and drivers have seen a major impact on their savings. It could seem as though the good old times are over. Gasoline at $4 a gallon is not something we can ignore, and if we take into account that Americans consume nearly 40% of the world's gasoline, you can see where the problems begin. So the surge in oil prices came with an imminent effect on consumers, who had to cut back on their spending.

But since we are already in this unpleasant situation, Kiplinger offers some solutions to help investors fight against high oil prices. Kiplinger underlines in this article that one smart move would be to minimize the cost of driving by making some good energy-related investments.

Gerry Jordan, manager of Jordan Opportunity, recommends investors invest in oil companies such as Schlumberger Ltd. (NYSE: SLB) and Weatherford International (NYSE: WFT), citing strong international business. In addition, Jordan believes that higher crude prices will increase drilling demand. On the other hand, Jordan also loves power companies like Calpine Corp. (NYSE: CPN) and Reliant Energy Inc. (NYSE: RRI) as he anticipates huge power outages across the globe during this year.

Readers of this space know that one argument forwarded here is that in the era of elevated energy prices the oil/natural gas services sector is likely to remain strong for the foreseeable future, barring the discovery of cheap, widely-available, alternative energy. And among oil/natural gas services companies, Schlumberger is worth an evaluation.

Oilfield services company Schlumberger (NYSE: SLB) (pronounced: "shlum-bur-ZJAY") is likely to benefit from growing demand for oilfield services technology, particularly in the high-technology-dependent Middle East, Africa and Eastern Europe regions.

Further, although North American margins have narrowed somewhat to-date in 2008, international margins remain large. Overall, in 2008 analysts see SLB's margins totaling 28% -- still a very healthy figure -- with revenue growth of 12-14% for 2008, and 16-20% for 2009.

Additional positives: Look for Schlumberger to continue to register solid revenue gains in the Eastern Hemisphere, as the company concentrates on higher-growth regions. The Reuters F2008/F2009 EPS consensus estimates for SLB are $4.80/$5.88.

"When it comes to oil services, the world's most dominant company by far is Schlumberger (NYSE: SLB)," says Stephen Leeb, editor of The Complete Investor. Here, he looks at this "extraordinary" company.

"The question isn't whether inflation will worsen-it's how to protect yourself. Major and obvious lifelines we've stressed include precious metal and commodity companies, especially ones able to boost production.

"For additional inflation insurance, look to what Warren Buffett likes to call 'great companies.' These have two crucial characteristics that allow them to take inflation in stride.

"First, a great company is so dominant in its market that it can pass rising costs along to its customers. And second, it's in a market growing faster than the world's economy.
