Oil drops after US inventory build, new output record

Oil prices fell on Thursday, extending losses from the previous session after official data showed U.S. crude and gasoline stocks rose against expectations as production hit a record.

Brent crude futures were down 18 cents, or 0.3%, at $63.88 a barrel by 0517 GMT, having dropped 0.3% on Wednesday.

US West Texas Intermediate crude fell 24 cents, or 0.4%, to $57.87, after falling 0.5% in the previous session.

Crude stockpiles in the United States swelled 1.6 million barrels last week as production hit a record high of 12.9 million barrels per day (bpd), the Energy Information Administration said. Analysts in a Reuters poll had forecast a drop of 418,000 barrels.
