Vintage Petroleum Temporarily Halts Production in California

Vintage Petroleum has temporarily shut-in net daily production of approximately 5,000 barrels of oil and 6,000 Mcf of gas in the company's Ventura County, California operations as a result of the heavy rains and mudslides experienced in the area over the last week. The volume temporarily shut-in represents approximately 7.6 percent of the 78,919 BOE of net daily volume produced in the third quarter of 2004. Activity is currently underway to assess the extent of the damage and to restore production to its previous level as quickly as possible, although it is expected that portions of the production will remain shut-in for several weeks.
