MADRID, Nov 12 (Reuters) - Spain's Repsol (REP.MC) is targeting still more cost cuts in 2010, including in its 5.5 billion euros ($8.25 billion) capex budget, the oil group said on Thursday after quarterly earnings beat forecasts.

The company moved to cut costs sharply in 2009 after weak refining margins and gas prices ate into profits, and by end-September it had saved about 611 million euros, although its cash position remained negative.

"I haven't reviewed the budget for 2010 but the initial figure is 5.5 billion euros... I have to shave this a little," the oil major's chief operating officer, Miguel Martinez, told analysts on a conference call after the results.
