NEW YORK (Reuters) - Brent crude prices dipped a penny in choppy trade on Tuesday, while U.S. crude rose for a second day as supportive U.S. data countered pressure from another batch of weak euro zone figures that reinforced concerns about future demand for petroleum.
Price consolidation should be expected, analysts and traders said, after Brent crude dropped below $100 a barrel on Friday for the first time since October. It has retreated from a 2012 peak above $128 a barrel in March.
They also noted that price drops during the session did not threaten multimonth lows posted on Monday.
"It has come off a long way, maybe now it's time to consolidate," said Tony Machacek, oil futures broker at Jefferies Bache.
Crude futures and equities prices received a lift from an industry report showing growth in the U.S. services sector picked up slightly in May.
Brent July crude dipped 1 cent to settle at $98.84 a barrel. The session low of $97.68 was nowhere near Monday's 16-month low of $95.63.
U.S. July crude edged up 31 cents to settle at $84.29, falling only to $83.31 intraday, well above Monday's $81.21 low.
Total Brent crude trading volume lagged U.S. crude turnover, with Britain's celebration of Queen Elizabeth's 60 years on the throne thinning trade. Both Brent and U.S. dealings trailed their 30-day averages.
Oil prices near $100 a barrel remain a threat to a slowing global economy, the International Energy Agency's executive director said on Tuesday.

The lack of an official joint statement after a teleconference held by Group of Seven finance ministers to discuss the euro zone crisis dashed expectations the call would result in dramatic initiatives.
Investors awaited results from Wednesday's European Central Bank (ECB) policy meeting and the Bank of England's on Thursday.
Also on tap is Federal Reserve Chairman Ben Bernanke's Thursday testimony before a congressional panel as investors sift central bank tea leaves for any clues about plans for bolstering a faltering economic recovery.
"G7 guidance ... failed to offer any major surprises and the market appears to be in holding pattern awaiting tomorrow's ECB indications," Jim Ritterbusch, president at Ritterbusch & Associates, said in a note.
