NEW YORK, Aug 21 (Reuters) - Oil prices rose on Tuesday as

hopes that the European Central Bank will act to contain the

region's debt crisis boosted crude futures and sent the euro to

a seven-week peak versus the dollar.

U.S. front-month September crude futures hit a three-month

high above $97 a barrel as the contract approached expiration.

Investors remained optimistic that the ECB could take action

to ease Spanish and Italian borrowing costs a day after the

central bank sought to quell speculation contained in a report

suggesting it was considering buying bonds of euro zone

countries if their borrowing costs breached a certain level.

An upcoming maintenance-related North Sea oil production

slide added support for oil, along with heightened tensions in

the Middle East as violence in Syria continues and Iran's

ongoing dispute with the West over Tehran's nuclear program.

Brent's sensitivity to North Sea production curbs and

potential Middle East supply disruptions has kept front-month

contracts priced above months further out, or in backwardation,

and provided the lift to bring prices back well above $100 a

barrel after settling at $89.23 on June 21.

On Tuesday, Brent October crude rose 94 cents to

settle at $114.64 a barrel, after reaching $115.58.

Brent hit a three-month peak at $117.03 last Thursday as its

September contract headed to expiration and went off the board

at $116.90 a barrel, the highest settlement since May 2.

Expiring U.S. September crude on Tuesday rose 71

cents to settle at $96.68 a barrel. The settlement and intraday

peak at $97.60 were the highest since May 10. The settlement was

just below the 200-day moving average of $96.73, after prices

tested above that level during the session.

U.S. October crude rose 58 cents to settle at $96.84

a barrel.

Total crude trading volume continued to experience a summer

lull, with Brent and U.S. crude turnover below their 30-day

averages and less than 500,000 lots traded.

"Optimism for a breakthrough in dealing with Greece is

propelling the risk appetite," Addison Armstrong, senior

director for market research at Tradition Energy said in a note.

Greek Prime Minister Antonis Samaras will meet German

Chancellor Angela Merkel, French President Francois Hollande and

Eurogroup chief Jean-Claude Juncker this week to try to secure

more funding from the European Union, International Monetary

Fund and ECB, despite falling behind on its targets to cut debt.

U.S. gasoline and heating oil rallied more

than 1 percent, adding more than 3 cents as recent refinery

problems keep supporting fuel prices.

Price strength for U.S. oil futures also came from concerns

about tropical weather threats, with Tropical Storm Issac headed

west toward the Caribbean.

Another low pressure system in the Atlantic is expected to

become a tropical cyclone in the next two days, the U.S.

National Hurricane Center said.

U.S. crude inventories fell 6 million barrels last week,

industry group American Petroleum Institute (API) said in its

weekly report on Tuesday, much more than expected.

Gasoline stocks rose 869,000 barrels, while distillate

stocks fell 1.0 million barrels, the API said.

The U.S. Energy Information Administration's inventory

report will follow on Wednesday at 10:30 a.m. EDT (1430 GMT).

Ahead of the weekly inventory reports, U.S. crude stocks had

been forecast to have fallen only 400,000 barrels, a Reuters

survey of analysts showed.

Distillate stocks had been expected to be up 1.0 million

barrels, with gasoline inventories down 700,000 barrels.

MIDDLE EAST TURMOIL

Turkey is investigating possible Syrian links to Monday's

deadly car bomb attack near its southeastern border,

highlighting concerns that the conflict might start to spill out

of Syria's borders.

Russian Foreign Minister Sergei Lavrov met China's top

diplomat and a Syrian government delegation on Tuesday, a day

after President Barack Obama said U.S. forces could intervene if

Syrian President Bashar al-Assad deployed chemical weapons

against rebels trying to topple him.

The U.N. nuclear agency and Iran will meet on Friday in

Vienna, the International Atomic Energy Agency confirmed on

Tuesday, for the first time since a June meeting produced no

progress towards answering questions about suspected nuclear

weapon research in the Islamic state.
