On CAPS, 97% of the 2,818 members who have rated Schlumberger believe the stock will outperform the S&P 500 going forward. These bulls include All-Star TDRH, who is ranked in the top 0.1% of our community, and KnockoutMouse.

Just last month, TDRH tapped Schlumberger as a particularly sharp selection: "The smart bunch. Recent acquisition of Smith covers the domestic market. Key will be the price recovery for Natural Gas. Global presence."

In fact, Schlumberger boasts a robust three-year average operating margin of 19.9%. That's higher than that of rivals Baker Hughes (13.3%), Halliburton (17.3%), and Weatherford (12.5%).

CAPS member KnockoutMouse listed several of Schlumberger's positives:

1. A clear leader in an industry with high barriers to competition.
2. Well managed and efficient: with a high ROIC and profit margin.
3. Strong balance sheet, free cash flow adequate to fund its dividend, and well managed debt.
4. A history of substantial dividends and dividend growth.
5. Has performed well in the current macroeconomic environment (i.e. inflation, loose monetary policy, rapid BRIC growth, dollar/euro weakness) by equaling or beating the return on gold (20% annually) over the last few years.

Schlumberger is the leading company in wire-line logging and geophysical exploration, both key oil field services. Another great play on Peak Oil.
