It sure looks cheap, on either an asset basis or on an operations basis.  On an asset basis PTR's ratio of enterprise value to proven reserves is $7/barrel of oil equivalent.  On an operations basis PTR is selling for a PE of 7, based on either trailing 12 months earnings or estimated 2008 earnings.
