NEW YORK (AP) — Oil is climbing as analysts and investors focus on the prospect of tighter supplies.

Barclays Capital said Friday that Libya's oil industry will be disrupted for longer than expected. Libya's daily exports of 1.5 million barrels were shut earlier this year as an anti-government uprising swept the country. The conflict has become a stalemate, and Barclays says it will take years for Libya to restore exports to their previous level.

Benchmark West Texas Intermediate crude for August delivery rose $1.33 to $97.02 per barrel on the New York Mercantile Exchange. Brent crude gained 66 cents at $116.92 per barrel on the ICE Futures exchange.

Meanwhile, gasoline pump prices added 1.2 cents Friday, rising to a national average of $3.667 per gallon.
