NEW DELHI (Reuters) - OPECâs Secretary General Mohammed Barkindo on Tuesday called on U.S. shale oil producers to help curtail global oil supply  warning extraordinary measures might be needed next year to sustain the rebalanced market in the medium to long term.
âWe urge our friends  in the shale basins of North America to take this shared responsibility with all seriousness it deserves  as one of the key lessons learnt from the current unique supply-driven cycle â said  Barkindo .
âAt the moment we (OPEC and independent U.S. producers) both agreed that we have a shared responsibility in maintaining stability because they are also not insulated from the impact of this downturn â  Barkindo  said  referring to a slide in oil prices that spurred OPEC to agree production cuts late last year.
While OPEC and some other producers  including Russia have cut supplies this year in order to prop up prices  U.S. production has soared by almost 10 percent this year  driven largely by shale drillers.  Barkindo  said  he  hoped that new producers  not just U.S. shale drillers  would join production cuts.
âDemand-supply is returning to rebalance through massive destocking that we have been witnessing of stocks in OECD across regions in a very massive way â  Barkindo  said later  speaking to reporters on the sidelines of the conference.
âIn the past four months alone  we have seen destocking to the tune of 130 million bpd â  he  said.
The aim of the OPEC-led cut is to trim the level of oil in OECD industrialized countries compared with the five-year supply average.  Barkindo  said the stock overhang to the five-year average stood at 171 million barrels in August  against 338 million at the start of the year.
âThe speed and pace (of destocking) has accelerated as a result of anticipated and projected demand growth in the second half of 2017 to the tune of 2 million bpd. We are witnessing a fast return to a balanced market â  Barkindo  said.
Still  on  Sunday Barkindo  said OPEC and other oil producers might need to take âsome extraordinary measuresâ next year to rebalance the oil market.
World oil demand growth in 2017 is expected at 1.45 million barrels per day (BPD) and it should stay around 1.4 million bpd in 2018   Barkindo  said.  He  said Indiaâs share of global oil demand is expected to rise to over 9 percent by 2040  up from 4 percent now.

Example Input: Could a small force of American soldiers have prevented Iraq from sliding back into chaos , as Governor Bush claims ? 
The exchange started like this : at the end of Jeb Bush 's town-hall meeting in Reno , Nevada , on Wednesday , a college student named Ivy Ziedrich stood up and said that she had heard Bush blame the growth of ISIS on President Obama , in particular on his decision to withdraw American troops from Iraq in 2011 . 
The origins of ISIS , Ziedrich said , lay in the decision by Bush 's brother , in 2003 , to disband the Iraqi Army following the toppling of Saddam Hussein 's government . 
Wow ," Bush said . 
Here is what happened : In 2003 , the U.S. military , on orders of President Bush , invaded Iraq , and nineteen days later threw out Saddam 's government . 
Historians -- along with Governor Bush and Ivy Ziedrich -- will be arguing about the question for a long time . 
"All right ," Bush said . 
Bush Administration officials involved in the decision -- like Paul Bremer and Walter Slocombe -- argued that they were effectively ratifying the reality that the Iraqi Army had already disintegrated . 
But the Bush White House went ahead . 
While it 's true that George W. Bush took actions that helped enable the creation of the Iraqi insurgency , and that some leaders of the insurgency formed ISIS , it 's not true that he "created" ISIS . 
And there 's a good argument to be made that an insurgency would have formed following the invasion of Iraq even if President Bush had kept the Iraqi Army together . 
Indeed , by 2011 the situation in Iraq -- as former Governor Bush said -- was relatively stable . 
But let 's get to Governor Bush 's assertion -- that Iraq went down the tubes because of President Obama 's decision to pull out all American forces , and that Obama could easily have left behind a residual force that would have kept the peace . 
"When we left Iraq , security had been arranged ," Bush said . 
A few days after that , President Bush or someone in his Administration decreed the dissolution of the Iraqi Army . 
Bush did n't like it : he offered a retort and then left the stage . 
So , on this , Governor Bush is n't entirely accurate , but makes a good point : the Obama Administration might have been able to keep some forces in Iraq if it had really tried .
