LONDON (Reuters) - Oil prices fell on Thursday after U.S. crude stocks hit an all-time high and official data showed Russian oil production unchanged in February, with no further cuts to tighten the market and drain global oversupply.
Benchmark Brent crude oil fell $1.06 a barrel to a low of $55.30, before recovering to around $55.70 by 1445 GMT. U.S. light crude was 70 cents lower at $53.13.
Crude inventories in the United States, the world's biggest oil consumer, rose by 1.5 million barrels last week to a record 520.2 million barrels, official figures showed.
Russia's oil output was unchanged in February from January at 11.11 million barrels per day (bpd), signalling a pause in Moscow's efforts to curb production as part of a global deal, energy ministry data showed on Thursday.
Crude oil prices slipped after the release of the Russian data but remained within tight trading ranges, supported by evidence of OPEC production cuts designed to reduce the oversupply that has weighed on prices for more than two years.

Russian Energy Minister Alexander Novak said on Thursday it was too early to say if the deal to reduce oil production would be extended beyond the end of June. OPEC, Russia and others are due to agree on output policy in the next three months.
"It is premature to talk of what we will discuss in April-May," Novak told Reuters in an interview.
Novak forecast Brent crude would average between $55 and $60 a barrel this year, with Russia's flagship Urals crude oil blend probably trading $2-$3 a barrel below that.
Oil prices have been unusually stable since oil producers agreed in November to reduce output, with both Brent and U.S. crude locked in $5 a barrel ranges.
"There is a very stale smell hanging over the market," Ole Hansen, head of commodity strategy at Saxo Bank in Copenhagen, told Reuters Global Oil Forum.
"I still see the risk of $50 a barrel before $60 on Brent, but have to acknowledge that we have so far seen very limited selling appetite."
