National Oilwell Varco will benefit from improving conditions in the global oil market, especially due to its investment in its deepwater drilling equipment business. Deepwater drilling is one of the only drilling markets that continues to see growth despite the decline in commodity prices. Since equipment used on deepwater drilling rigs is more complex and expensive than that used on land or on shallow-water rigs, NOV generates high profit margins in its deepwater drilling equipment business. One potential ongoing catalyst for National Oilwell is a series of deepwater oil projects spearheaded by Petrobras in Brazil. Estimates suggest Petrobras will need at least 28 new ultra-deepwater rigs to develop all of the fields it has discovered. More deepwater and ultra-deepwater drilling activity translates into higher revenues for National Oilwell Varco.
