The survey also focused on what would happen to oil prices if the U.S. were to lift the ban on exporting crude. Forty-six percent said they expect the price of oil to rise, while 36 percent said it would have no impact. Another 14 percent said lifting the ban could result in lower prices.
In comments submitted with the survey, several respondents said they see another selloff this year even if oil prices already set their lows for 2015.
Tom Kloza, co-founder and head of global energy analysis at OPIS, said oil and gasoline should slide in August through December. "Only a Gulf Coast hurricane might avert that action, and most hurricanes impact demand more than supply," he said.
Kyle Cooper at IAF Advisors said it's unclear whether the bottom is in yet for the year.
"I think there is roughly 50/50 chance the low is in. Big U.S. product builds during the summer and a European/Greece debacle that results in a plunging euro and surging U.S. dollar may lead to new lows," Cooper wrote. But another view from a participant is that the euro could strengthen and push up the price of oil.
Michael Cohen, head of energy commodities research at Barclays, said in an interview that he does believe the lows are in for the year, but he sees potential for a correction in the third quarter.

"After that I think we'll start moving back into the $70 area by the end of 2016 and probably mid-$60s by the end of the year for Brent."
Cohen said the market could be pressured by new supply from countries outside the U.S., like Iran.
"I do think we'll see a slowdown in the U.S. production. Elsewhere, we still have the ability to increase output in Iraq," he said, adding there also could be more oil coming from Iran even if nuclear negotiations are not completed. "I think that's all going to hang over the market."
Alan Harry of Spartan Commodity Fund wrote that the market will be oversupplied when Iran returns. "I feel the markets will over react and cut real production bringing the price of crude to higher levels in 2016," he said.
Iran has been one of the wild cards for the oil market, as it is unclear whether its talks on a nuclear agreement will lead to a deal this month that allows Iran to return to the oil market.
"The rebalancing of global oil supply and demand is clearly progressing while inventories will likely remain in surplus for a few more quarters, by the middle of next year things should be tight again. Risk to our central scenario feel biased to the upside and center on supply from the Mideast," wrote Jan Stuart, global energy economist at Credit Suisse.
