Oil prices steady as reviving shale balances OPEC cuts

By Christopher Johnson LONDON (Reuters) - Oil prices steadied on Tuesday as lower production by OPEC and other exporters balanced growing evidence of a revival in U.S. shale production and sluggish demand. Benchmark Brent crude was trading at $55.72 per barrel by 0850 GMT, unchanged from the last close. On Monday, the Brent futures contract closed down $1.09 a barrel.
