Aramco said the attacks would cut output by 5.7m barrels a day, more than 5% of global crude supply.
Officials said the photos show impacts consistent with the attack coming from the direction of Iran or Iraq, rather than from Yemen to the south. But Saudi and United States officials have cast doubt on that narrative, arguing that evidence suggested the attack was launched from Iran.
But a senior USA official told ABC News Saturday that was false: "It was Iran".
Iran on Sunday denied it was behind the attack, but the Yemeni Houthi militia backed by Tehran, claimed they had launched them.
Despite the denials, USA satellite imagery showed the attack did not come the south - where Iranian-backed Houthi rebels are located - but instead came from Iran's direction, the Associated Press reported.
In early Asian trading, futures for US 10-year Treasury notes rose 0.2 percent, indicating yields may slip when cash trading begins. "There is no evidence the attacks came from Yemen", he wrote on Twitter.
The Iranian foreign ministry dismissed Pompeo's allegations as groundless.
Washington has imposed its "maximum pressure" strategy on Iran since a year ago when Trump pulled out of an global deal that gave Tehran access to world trade in return for curbs on its nuclear program.

An American senator has called for Washington to consider an attack on Iranian oil facilities as pressure grows in the U.S. for a firm response to the Saudi Aramco strikes. It has not yet blamed any party for Saturday's strike, but linked it to a recent series of attacks on Saudi oil assets and crude tankers in Gulf waters.
Saudi Arabia is expected to tap into their reserves to cope with the exports for this week, BBC reported.
Another source briefed on the developments said Saudi oil exports would continue to run as normal this week thanks to large storage in the kingdom.
For the 12 months ended in June, the US West Coast imported an average of 11.40 million barrels every month of Saudi crude, much of it going to a number of refineries based in California, according to the US Energy Information Administration.
The senior official told ABC News the president is fully aware that Iran is responsible, but he wants the Saudis to acknowledge it if they want US help.
Trump also disputed the idea of unconditional meeting with Iran even though his advisers have said he's ready and willing.
The disruption represents half the output of the kingdom, which is the world's biggest oil supplier.
