Drill, baby, drill was the calling card of the Republican Party during the last presidential election.

With high oil prices and rising demand, finding new sources of oil is imperative. Given environmental concerns, offshore drilling is one space that still offers meaningful potential to increase domestic supply.

Diamond Offshore Drilling (NYSE: DO) operates some 45 deep water rigs that are keeping extraordinarily busy with oil prices on the rise.

This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"One stock that could get a November bounce should McCain win is seismic firm CGG Veritas (NYSE: CGV); the Republican mantra has been 'drill, drill, drill' and this company helps find out where to do that," says Bill Martin in his BullMarket.com.

"If McCain wins office and is able to get Congress to pass his drilling initiatives for offshore drilling (one stronger than the bill that was just recently passed by Congress), the first step will be to find where exactly this oil is located.

"That is where French seismic company CGG Veritas comes in. It calls itself 'the world's leading international pure-play geophysical company.' The company was born in January of 2007 as the result of a merger of the former Compagnie Générale de Géophysique and Veritas DGC.

"The company provides seismic data and services to the oil and gas industry, and manufactures seismic equipment through its Sercel subsidiary for sale to other seismic companies.

"The company conducts seismic surveys on a contract and multi-client basis. The job entails acquiring, processing, and interpreting land and marine seismic data, and producing images of the subsurface in multi-dimensional and multi-component formats.

"Those pictures are used to identify new oil and gas structures and manage existing reservoirs. It also has up to 40 land-based teams that can be put in the field and can work in a variety of terrain.

"With CGG Veritas's stock beaten down -- despite solid earnings and guidance -- and trading at an attractive valuation, a McCain win could be the cure to its recent ills."

"Crude oil remains deeply oversold on an intermediate-term basis, suggesting a rally sometime in the early fall," says Dennis Slothower.

The editor of Stealth Stocks looks to Petroleo Brasileiro SA (NYSE: PBR) as his latest "stock of the month." Here's his review of the Brazilian firm that is now the world's 8th-largest oil company.

"The founding of Petrobras was authorized in October 1953, with the objective of executing, on behalf of the federal government, the activities of the oil sector in Brazil.

"Over the past five decades or so, the company has become the country's leader in the distribution of oil products, an activity not covered by the government monopoly, and today it is internationally acknowledged as the eighth-largest oil company in the world.

"Leading the sector in the development of one of the most advanced deepwater and ultra-deepwater technologies for oil production, PBR was twice (in 1992 and 2001) awarded the Offshore Technology Company (OTC) prize, the most important award in the sector.

"We are moving headlong into oil," notes John Reese, who analyzes stocks based on the criteria used by "legendary" investors such as Buffett, Graham and Lynch.

In his Validea newsletter, he says, "My fundamental models indicate that the oil industry is where the best values in the market are." Here's a look at W&T Offshore (NYSE: WTI), which is based on the criteria used by contrarian David Dreman.

"The economy and stock market have gone through a legitimate crisis because of the credit woes, and it takes time for something like that to work itself out.

"But the important thing to remember is that we've been through financial crises before -- even bad-debt financial crises like this one -- and the market has always stabilized and then pushed higher.

"And history has shown that those who can stick with the stock market through down times like these will be rewarded.

"David Dreman -- one of the gurus I base my strategies on -- notes in his recent Forbes column, 'If you pack up now, chances are you'll miss a good part of the next bull market. A large part of the gains are always made in the first few months of one, when market-timing investors are still on the sidelines.'

It's time to start drilling for oil and natural gas offshore on the east and west coasts. We are wasting our time and our money, and risking our future by not doing so. The energy needs of the United States have made oil our number one import and the biggest factor in our imbalance of trade.

It is not just that oil holds us hostage to the rest of the world. This imbalance of trade means we cannot support ourselves and must borrow from others to get by, and I, for one, have a very hard time with that notion. I prefer independence -- remember that? I think it was an important concept in our founding, way back when.

The imbalance in trade is a mortgage against the future of our children and it is getting worse year after year. The money often goes to foreign governments whose interests are not aligned with ours and they hold us politically and economically captive. Nothing is more shameful than President Bush pleading with Saudi Monarchs to pump more oil.

It's a reality of the era of elevated energy prices that the oil/natural gas services sector is likely to remain strong for the foreseeable future, baring the discovery of a cheap, widely-available alternative energy. And among oil/natural gas services companies, Transocean (NYSE: RIG) is a standout.

Transocean offers deepwater drilling services in the world's major offshore oil-producing regions, including Africa, Asia, Brazil, Canada, India, Middle East, Gulf of Mexico, and the North Sea.

In general, analysts see RIG generating a 18%-25% total return on equity for 2007-2009, with an upside possible, given the company's strong position in deepwater drilling, which offers a higher return potential than shallow water drilling. And currently, it looks like a 2008 upside is in sight for Transocean: of the company's 82 offshore rigs, only seven have not been committed for 2008. Further, given a capacity shortage sector-wide, dayrates have increase substantially, and look for RIG's pricing power to continue past 2009. (RIG's dayrate for 2006 increased 35% to $142,000 and its rig utilization rate improved 5% in 2006.) The Reuters F2007/F2008 EPS consensus estimates for RIG are $8.01/$11.32.

The risks? RIG's dayrate increases could slow if major oil companies begin to reduce exploration budgets. A U.S. recession could also substantially decease home building, which could lower the demand for oil.

The First Call mean rating for RIG is: Buy. [34 firms.] Mean 2007 target: $131.00. [high: $168, low: $89.] Transocean's share were down $2.04 to $127.60 in Wednesday afternoon trading, but view that dip as a buying opportunity, as it's reasonable to assume that the industrialized nations will need oil services companies for a few years, to say the least.

Stock Analysis: Transocean is a moderate-risk stock not suitable for low-risk investors. Investors with an investment horizon longer than 1 year should be rewarded from RIG's shares. Sell / Stop Loss: $84.

Leo Fasciocco is a technical specialist who focuses on finding breakout buys -- stocks that have broken out from their trading bases and are poised, in his view, to move higher.

In his Ticker Tape Digest he has isolated two intriguing energy plays: Diamond Offshore Drilling Inc. (NYSE: DO) searches for energy below the sea, while solar firm Suntech Power Holdings Co. (NYSE: STP) looks skyward.

The advisor explains, "Diamond Offshore has 30 semisubmersibles, 13 jack-up rigs (mobile drilling platforms), and one drillship. They operate around the world. The company contracts with major oil and gas companies.

"DO's profit outlook is excellent and should be the driver to send the stock higher. Technically, the stock's long-term chart shows a powerful bull market. It has soared from 20 to 113 the past three years, riding the rising price of crude oil.
