On Tuesday evening, the top officials of the Saudi oil industry held a news conference and delivered a very upbeat message. Saudi Arabia’s production capacity, which had been crippled by last weekend’s aerial attack, would be “fully restored” by the end of September, according to Saudi Aramco, the national oil company.

If that pace of recovery seems almost miraculous, it is.

Saturday’s attacks cut Saudi output by more than half. Analysts say that while the kingdom has been able to restore some of that output, the effects of the onslaught on two key facilities are likely to linger for weeks or even months.

“We are certainly expecting some disruption and restriction to continue at least into November,” said Richard Mallinson, an analyst at Energy Aspects, a London-based market research firm.

Mr. Mallinson and other analysts say that while Aramco struggles to repair its damaged facilities, it is striving to calm the markets and create a sense of normality.
