Oil traded near the lowest close in two months as U.S. oil producers continued to revive drilling in the shale patch, adding rigs for the fourth consecutive week in the longest streak of increases since August.
Futures fell as much as 0.4 percent in New York after dropping 1.3 percent on Friday. Rigs targeting oil in the U.S. rose by 14 to 371 last week, after 27 had already been added since the start of the month, Baker Hughes Inc. said on its website on July 22. U.S. crude and gasoline supplies are at the highest seasonal levels in at least two decades, government data show.
Oil retreated in recent weeks as a rally spurred by supply disruptions in Nigeria and Canada and falling U.S. output lost momentum. Prices remain up about 68 percent from a 12-year low in February, a recovery that has prompted American producers to begin returning drilling rigs to service.
