Just last week, one of those Fools, dsciola, highlighted several of National Oilwell's positives:

90% of global oil rigs have [National Oilwell] parts on them and [National Oilwell] has approx 60% of global mrkt share. ... High switching costs for customers due to nature of product as well as presence of [National Oilwell] 'stores' on rigs, technical systems, and ability to train customer employees ... Considered as growth play due to growing demand of emerging market need for energy and continued global preference for oil as #1 energy source … Admittedly, not contrarian play at moment due to recent spike in gas prices and Iran concerns; betting on being part of more longer term trend / catalyst for higher oil prices.
