Fed's Kaplan says oil at $55 to $65 a barrel would boost U.S. rig count

HOUSTON (Reuters) - Dallas Federal Reserve Bank President Robert Kaplan on Friday said that he would expect U.S. oil producers to ramp up their rig count once the price of crude rises to $55 to $65 a barrel.

But, in comments to reporters on the sidelines of a conference on oil at his bank's Houston branch, he said it would be "challenging" to get to an OPEC freeze or cut in production, and said he is taking a wait-and-see approach.

U.S. drillers added 19 rigs last week, the largest weekly gain in 16 months, according to data from energy services firm Baker Hughes. Although U.S. oil futures traded about $50 a barrel for much of October, prices have since fallen, and on Friday were trading around $45 per barrel.
