Berry Petroleum is an independent oil and gas production
company. Year-end 2008 reserves of 246 mboe, comprised 51% of oil,
consist of heavy oil in California, natural gas in east Texas, and
light oil and natural gas in the Rocky Mountains. Current
production is weighted 68% to oil. In addition to its oil and gas
operations, Berry operates three natural gas-fired electrical/steam
cogeneration facilities. Berry uses the steam to facilitate
recovery of its heavy oil reserves.
