Saudi Aramco looks deeper into Ghawar

RIYADH, Saudi Arabia, Sept. 28 (UPI) -- New technology to tap into porous rock formations in the Ghawar oil field in Saudi Arabia could expand production at the giant field, the operator said.

The Ghawar field, believed to be the largest oil field in the world, pumps around 6 percent of the world's crude oil output. The field is producing around 5 million barrels of light crude oil and roughly 2.5 billion cubic feet of natural gas per day.

Saudi Aramco, the kingdom's state-owned national oil company, said it was analyzing a new formation in the field to exploit previously untapped resources, Dubai's news agency Emirates 24/7 reports.

"The researchers found an extensive micro-pore system of hidden passages in carbonate rock, where a significant percentage of unrecovered oil resides," the company said.

Researchers didn't reveal the resource potential of the latest find, however. Saudi Aramco believes there are more than 71 billion barrels of proven oil reserves remaining in the field.
