In his Validea newsletter, John Reese assesses stocks using specialized screens based on the stated criteria of legendary stock market investors.

One such screen -- which has resulted in his best-performing model portfolio -- is based on the value-oriented investment strategy of Benjamin Graham.

Here, he looks at oil services firm Tidewater (TDW), which scores 100% on his Graham-style model.

While other earnings may have disappointed last week, the news was good for oil giant ConocoPhilips (NYSE: COP). In what some took as a good sign for big oil, the Houston-based company reported that third quarter net income surged 41% year over year to $3.39 per share, and that revenue also surged 52% to $70 billion. We'll see whether the good news extends to other petroleum giants scheduled to report quarterly results this week.

Analysts surveyed by Thomson Financial are looking for BP (NYSE: BP) profits to have grown 43.2% in the most recent quarter to $2.34 per share on revenue of $109.7 billion, and Chevron Corp. (NYSE: CVX) to post earnings up 39.4% to $3.25 per share on revenue of $86.8 billion. Marathon Oil Corp. (NYSE: MRO), ExxonMobil Corp. (NYSE: XOM), and Royal Dutch Shell (NYSE: RDS.A) likewise are expected to report higher net income of $2.33 per share (sales of $23.4 billion), $2.40 per share (sales of $131.4 billion), and $2.65 per share, respectively. Even Valero Energy Corp. (NYSE: VLO) is expected to post earnings slightly higher to $1.46 per share (sales of $36.4 billion), despite the effects of Hurricane Ike. Among these companies, only BP and Valero beat earnings expectations in the previous quarter. Not surprisingly, analysts on average recommend buying all except Valero, and shares of all of these companies have recently hit 52-week lows.

TheStreet.com's Jim Cramer says the companies could deliver money to shareholders without sacrificing growth.

What happens if the oil companies start actually recognizing their good fortune -- their sustainable good fortune -- and start boosting dividends the way that Tidewater (NYSE: TDW) (Cramer's Take) did last week with its 67% hike.

Throughout this great run with oil and gas, it seems that the companies themselves haven't caught up with the good fortune. They haven't spent that much on drilling relative to profits, and they have chosen to buy a lot of stock back, never bad. But what if they start returning the profits to shareholders in the form of dividends?

I think that what could happen is that you wouldn't think that Chevron (NYSE: CVX) (Cramer's Take) and Occidental Petroleum (NYSE: OXY) (Cramer's Take) and Exxon (NYSE: XOM) (Cramer's Take) are such nose-bleeders.
