Oil prices rose on Tuesday for the fourth consecutive session, as weak shale output in the U.S. spurred further concerns about a supply deficit stemming from extended production cuts by Saudi Arabia and Russia.
U.S. West Texas Intermediate crude futures rose 99 cents, or 1.1%, to $92.47, by 0400 GMT, while global oil benchmark Brent crude futures rose 58 cents, or 0.61%, to $95.01 a barrel.
Prices have gained for three consecutive weeks, and are now around 10-month highs for both benchmarks.
