Oil prices fall as reviving shale balances OPEC cuts

By Christopher Johnson LONDON (Reuters) - Oil prices fell on Tuesday as lower production by OPEC and other exporters was undermined by growing evidence of a revival in U.S. shale production and sluggish demand. Benchmark Brent crude was down 70 cents at $55.02 a barrel by 1430 GMT. On Monday, the Brent futures contract closed down $1.09 a barrel.
