LONDON (Reuters) - Oil prices fell on Tuesday ahead of weekly U.S. crude inventory data that is expected to hit another high, withdrawing further from a rally that saw Brent crude futures touch a 4 1/2 month high on Friday.
U.S. commercial crude stockpiles were expected to have risen last week for the 16th straight week, up from a record 489 million barrels, even though drilling activity fell, a preliminary survey by Reuters showed on Monday.
"Crude oil has made a strong price recovery on the expectation that you would start to see lower U.S. production and also some strock draws," said Olivier Jakob of Swiss-based consultancy Petromatrix.
"We need to have some confirmation of that in the statistics before we can rally further."
Brent June crude futures fell 43 cents to $64.40 a barrel by 0920 GMT. U.S. June crude fell 40 cents to $56.59 a barrel.
