U.S. crude oil futures settled lower on Friday, extending losses for a second week after Saudi Arabia was reported offering more oil to Asian buyers and raising output in July.
The dollar rose against the euro and a basket of currencies, also pressuring crude futures as it prompted investors to reduce holdings of riskier assets.
On the New York Mercantile Exchange, crude for July delivery settled at $99.29 a barrel, down $2.64, or 2.59 percent, after trading between $98.60 and $102.15.
For the week, the contract fell 93 cents, or 0.93 percent, from the $100.22 close on June 3.
