WASHINGTON: US President Barack Obama, under pressure from Republicans and the public to bring down gasoline prices, announced new measures on Saturday to expand domestic oil production in Alaska and the Gulf of Mexico. High fuel prices have dented Obama's ratings in opinion polls and threaten to dampen the economic recovery that is critical to his re-election in 2012. The president, a Democrat, has pushed for reducing US oil consumption and expanding renewable energy sources while also focusing on domestic oil and gas production – an area Republicans want to expand dramatically. In his weekly radio and Internet address, the president met some of those Republican demands, outlining ways to boost domestic drilling and better coordinate the process of issuing permits in Alaska. “I am directing the Department of Interior to conduct annual lease sales in Alaska's National Petroleum Reserve, while respecting sensitive areas, and to speed up the evaluation of oil and gas resources in the mid and south Atlantic,” Obama said in the address. Government lease sales give energy companies the opportunity to rent offshore or onshore federal tracts, which can be drilled for oil or natural gas. Companies with the highest bids generally lease the tracts for 10 years. Alaska's National Petroleum Reserve is a 23 million-acre area originally set aside in 1923 as a fuel source for the US military. It is located in the northwest corner of Alaska near the Arctic National Wildlife Refuge (ANWR), which the Bush administration tried to open for exploration against objections from environmental groups. Energy companies have long dreamed of tapping oil reserves beneath that site, a home to herds of migrating animals. A senior Obama administration official said the White House remained firmly opposed to drilling in that arctic refuge. Alaska's NPR is a different story, however. Rising crude prices have boosted the amount of oil that can be recovered economically from that area, even though it holds less oil than previously thought, the government said last week. The White House is increasingly concerned about the effects of rising oil prices on US consumers and on Obama's political prospects. While acknowledging the importance of domestic drilling, it has repeatedly said domestic production is not a panacea to solve the country's energy woes. Taking new measures to boost drilling addresses criticism from some lawmakers in both parties, who put pressure on the administration to make it easier for energy exploration to continue in the Gulf of Mexico after the BP oil spill. The administration banned new exploration on offshore leased tracts for about six months after the spill. The president said the Interior Department would extend the life of the affected leases to make up for the lost time companies had to explore for oil and give them more time to meet safety requirements. That was one of the requirements of Republican-backed legislation approved this week in the House of Representatives to boost offshore drilling. The legislation would also require the government to hold certain lease sales in the Gulf, which administration officials said the department would do by mid
