LONDON (Reuters) - Oil rose above $60 a barrel on Friday for the first time this year, bringing gains this week to 4 percent, supported by signs that deeper industry spending cuts may curb excess supply.
Also supporting oil, euro zone economic growth accelerated unexpectedly in the final quarter of 2014 as the bloc's largest member, Germany, expanded at more than twice the expected rate.
The price of Brent crude collapsed from $115 in June to $45.19, the lowest in almost six years, in January due to oversupply. Since January, mounting signs of lower industry spending have helped prices rally by more than 30 percent.

"During the last weeks, crude oil rebounded driven by improved market sentiment and by expectations that low prices will lead to lower supply growth in 2015," said Daniela Corsini, analyst at Intesa Sanpaolo, in a report.

"Seeing today's prices, supply will probably not keep pace with this growth. It may even decline, as prices are close to cash costs," said Shell Chief Executive Ben van Beurden.
Still, analysts at JBC Energy in Vienna said in reference to Apache's moves that spending cuts can easily be reversed.
"While the company expects North American onshore production to be flat this year, they emphasize their flexibility to come back very quickly if the price environment or the cost structure changes sufficiently," JBC said.
"This is generally what makes most people doubt that the latest rally can be sustained."
A weaker U.S. dollar, which makes dollar-denominated commodities cheaper for holders of other currencies, has also supported oil this week, analysts say.
