OSLO (Bloomberg) — Seadrill Ltd., the world’s sixth-largest offshore oil driller, said it expects to win more contracts a day after securing $970 million for one of its rigs, sending shares up by the most in seven months.Bermuda-registered Seadrill also decided to order another deep-water rig because of the strength of offshore drilling, the Stavanger, Norway-based company said in a statement yesterday.

The company’s shares rose as much as 7.8 percent, the most since September, and were up 7.5 kroner, or 7.5 percent, at 106.25 kroner as of 3.43 p.m. in Oslo. It was the best performer in the 26-stock Dow Jones Europe Stoxx Oil & Gas index.

On Wednesday, Seadrill won a five-year contract from an unnamed oil company for one of its deepwater rigs under construction in South Korea and Singapore.
