UPDATE 8-Oil prices drop off 3-year highs but strong demand supports

* OPEC/Russia-led supply curbs prop up crude

* Goldman Sachs sees upside to oil price forecast

* Morgan Stanley, BofAML raise price forecasts

* U.S. oil output has stalled amid icy weather

* U.S. output still set to break above 10 mln bpd (Adds comments, updates prices)

NEW YORK, Jan 16 (Reuters) - Oil prices dropped off three-year highs on Tuesday as traders booked profit from a recent rally but healthy demand underpinned prices near $70, a level not seen since the market slump in 2014.

Prices have been driven up by oil production curbs in OPEC nations and Russia, and demand amid healthy economic growth.

Imports to India, the world's third-biggest oil consumer, rose by about 1.8 percent in 2017 to a record 4.37 million barrels per day (bpd) as the country boosted purchases to feed its expanded refining capacity.

Brent futures fell $1.05, or 1.5 percent, to $69.21 a barrel by 12:25 a.m. EST (1725 GMT) after hitting a session low of $68.92. Traders said Brent, the global benchmark, was well supported overall at around $70.

Brent hit a peak of $70.37 on Monday, matching a high from December 2014 at the start of a three-year market decline.

U.S. West Texas Intermediate (WTI) crude futures were at $63.70 a barrel, down 60 cents, or 0.9 percent. WTI hit a December 2014 peak of $64.89 earlier in the session.

"It's such a quiet day ... I think this is a pause as you try and decide what the rise in rig counts means and what the Russia comments mean," said Rob Haworth, senior investment strategist at U.S. Bank Wealth Management.

Reacting to the recent three-year high, Russian Energy Minister Alexander Novak said the oil market was not yet balanced and that the global deal to cut output should continue as the price rise could be due to cold weather.

The U.S. rig count, an early indicator of future output, rose by 10 oil rigs last week to 752 and is much higher than a year ago when only 522 rigs were active.

"All in all, this is still a pretty positive day because even though there is no news to drive prices, you're not giving up much ground here," Haworth said.

Most analysts and market participants said oil is vulnerable to profit taking as hedge funds and money mangers have amassed a record number of bullish bets on U.S. crude.

In addition, trading was thin on Monday due to the Martin Luther King Jr. Day holiday in the United States.

Fundamentally, oil has been pushed higher by an effort led by the Organization of the Petroleum Exporting Countries and Russia to withhold production since January last year. The cuts are set to last through 2018.

The restraint has coincided with healthy oil demand, pushing up crude by almost 15 percent since early December.

"This rally has been driven first by robust fundamentals, with strong demand growth and high OPEC compliance accelerating," U.S. bank Goldman Sachs said in a note.

"We see increasing upside risks to our $62 per barrel Brent and $57.5 per barrel WTI forecast for the coming months."

Other banks, including Bank of America Merrill Lynch, Societe Generale and Morgan Stanley, have raised their price forecasts.

"Our view is that prices are overheated, and will correct lower," SocGen said in a note. "We believe that the current situation, with strong uplift from fundamentals, non-fundamentals, and geopolitics all at the same time, is not sustainable."

A factor that held back crude prices in 2017, the surge in U.S. production, has stalled at least temporarily due to icy winter weather.

U.S. production <C-OUT-T-EIA> has fallen from 9.8 million barrels per day in December to 9.5 million bpd currently.

However, most analysts still expect U.S. output to break above 10 million bpd soon.
