NOTICE REGARDING 2004 FIELD PRODUCTION!
PLEASE READ!
During the month of December, 2004, one oil gatherer did not report the
majority of their oil purchases to commercial information gathering
services. To account for the unreported volumes, production estimates
were made by ISGS Oil and Gas Section staff member
Bryan Huff on a lease
by lease basis based on production histories before and after the
non-reported period. The total unreported volume for 2004 in Illinois
is estimated at 157,350 barrels.
Estimates were also made for 2005. See
2005 annual report for details.
The values were totaled on a field basis and added to reported values
for a field.

Example:
for 2005 in Allendale field old gatherers reported buying 156,600 bbls
of oil. A correction of 2,800 bbls was estimated for the non-reporting
gatherer for December giving a total of 159,400 bbls for Allendale field
in 2004 as listed in the annual report.

The corrections below (in bbls) were added to 2004 reported field
production values. If a field is not listed, no correction was
deemed necessary.
