* Set to leave output target unchanged
* U.S. shale means hotter contest for Asia market
* No resolution on secretary-general choice expected (Adds Libya paragraph 4)

VIENNA, May 30 (Reuters) - OPEC oil exporters on Thursday, set to leave output policy unchanged, were weighing the impact of rising supplies of U.S. shale oil that are redrawing the landscape of global oil trade.
The Organization of the Petroleum Exporting Countries has little room to pump more oil due to the U.S. oil boom that has sparked competition for marketshare in Asia and set off a rivalry between its top two producers Saudi Arabia and Iraq.
At a meeting in Vienna on Friday the 12-member group is expected to stick with its 30 million barrel a day (bpd) output target for the last six months of 2013.
“Everything will be as before, we will maintain the production level,” said Libya’s Oil Minister Abdelbari al-Arusi.
A year ago, OPEC gave shale oil short shrift, but now it is a hot topic. Gulf producers are of the view that OPEC will still be able to pump at least 30 million bpd, provided U.S. shale grows at a moderate pace.
“Shale oil is not a threat, but it changes the dynamics of where the oil is going. There will be more competition in Asia,” said a Gulf OPEC source.
Despite the growing supply, oil is comfortably above $100 a barrel, well below the $125 that rang alarms in major consumer countries last year.
But triple digit oil has also unlocked vast amounts of U.S. shale oil in North Dakota and Texas - which competes with OPEC crude of similar, light quality from Nigeria and Algeria, rather than heavier Saudi output.
Nigeria, along with Algeria, has already felt the heat from the U.S. oil boom, losing ground in its most lucrative export market and diverting sales to Asia.
Fast-growing exporter Iraq is also fighting for more Asian market share, competing with regional rival Saudi Arabia.
“We are looking to increase our exports and we aim to make our crude more competitive in the market,” Iraq’s Oil Minister Abdul Kareem Luaibi told reporters in Vienna.
The United Arab Emirates, also building up capacity, has the region in its sights, but downplayed the prospect for battle.
“I‘m not of the view that competition in Asia is going to distort the price,” UAE Oil Minister Suhail bin Mohammed al-Mazroui told Reuters.
Innovative use of hydraulic fracturing, or “fracking,” has put the United States in line to become the world’s largest oil producer by 2017, overtaking Saudi Arabia.
That is not worrisome for Riyadh, especially when it comes to charting policy for the second half of 2013.
And the kingdom - holder of most spare capacity in OPEC -shows no sign of opening the taps to bring down prices and curtail that output by making it uneconomic.
By the end of last year, the United States had recorded the biggest annual rise in oil output since it first pumped oil in the early 1860s. The 850,000 bpd increment was more than each of OPEC’s two smallest producers, Qatar and Ecuador, pump in total.
Surging non-OPEC production has not prompted so much debate in the cartel in more than a decade, but there is no common view. While Saudi’s Naimi welcomes it, his Nigerian counterpart Diezani Alison-Madueke has said it will have a “major impact.”
Others within OPEC, including price-hawk Iran, are concerned about the potential for both slow global growth and a dramatic rise in U.S. shale oil to send prices tumbling.
“Recently we have had a more than $10 decline in prices, some factors are due to the supply side, including shale, and others are due to the demand side,” said an OPEC delegate from a non-Gulf country.
But the group that pumps a third of the world’s oil is not known for contingency plans.
OPEC delegates now say this meeting will not be electing a new secretary general - stuck in a logjam of competing candidates from Iran, Iraq and Saudi Arabia - but will merely approve the criteria for prospective candidates to come forward. [ID: nL6N0DI1C0]
With change in the output ceiling unlikely, short-term market management will be guided by OPEC’s leading producer Saudi Arabia - the only member with significant unused capacity - supported by the UAE and Kuwait.
Saudi Arabia has cut back from a 30-year high reached in 2012 of 10 million bpd, pumping 9.30 million bpd in April. That has helped bring overall OPEC production down to 30.46 million bpd, 460,000 bpd above the target.
Iran’s crude exports fell back in May to around 1.00 million bpd from 1.1 million bpd in April, according to a Reuters survey on Thursday, reflecting the impact of U.S. and European sanctions on sales.
While challenges loom in the medium term, the numbers for the rest of 2013 suggest some breathing space for OPEC.
Demand for OPEC crude is set to rise in the second half to average 30.47 million bpd, up from 29.14 million bpd in the current quarter, according to OPEC forecasts. So if OPEC holds output at April’s rate, supply would match the average requirement in the second half of 2013. (Additional reporting by Amena Bakr and Peg Mackey, editing by William Hardy)
