This article by Travis Hoium from the Motley Fool states:
While onshore drilling in the U.S. saw rig activity drop like a rock early in 2015, the same can’t be said for offshore drilling, especially in deepwater. The projects Seadrill is drilling take months, or even years, to complete, and contracts are signed over these durations by oil explorers. They’ll take the lumps of low oil prices in the short term because they have a decade-long view of the value of these wells.
Offshore oil is a key for the oil industry
Based on the media’s coverage of the shale boom in recent years, it may seem like that’s the only segment of the energy industry that’s important right now. But offshore drilling is a key to the industry’s future, and U.S. companies, Brazil’s Petrobras, OPEC, and even African countries are betting billions on its future.
These bets on offshore drilling aren’t a passing fad, like much of the shale boom looks to be today. They’re based on the industry’s realization that offshore oil is going to fill the reserve needs to fund future revenue. And if OPEC is right, and oil approaches $80 per barrel by 2020, the demand for offshore rigs will pick up again.
That should benefit Seadrill, which has the backlog to limp through the next couple of years and wait for a stronger offshore drilling market. The long-term nature of offshore drilling works in the company’s favor, and that’s why I’m staying bullish on this floundering energy stock.
