EIA Adjusts Storage Data For ANR Change
The Energy Information Administration reported that 47 Bcf of
working gas in Michigan storage facilities was reclassified as base
gas in March, which means working gas levels at the end of the
winter heating season were 3% lower than first reported, or 1,430
Bcf compared to 1,477.
The revised level of working gas at the end of March still was
245 Bcf more than at the same time a year earlier and still was the
highest level in the past seven years - at the end of March in 1992
there was 1,545 Bcf of working gas, but the record level was
achieved in 1983 with 2,148 Bcf of total working gas in storage.
ANR Pipeline confirmed it was responsible for the
reclassification. In its last rate case ANR requested that 62.1 Bcf
of working gas in its Michigan storage fields be reclassified as
base gas, and about 15 Bcf of that was located in five fields that
later were abandoned or no longer used for storage: Coldwater,
Croton, North Hamilton, Norwich and Orient.
"For accounting purposes it was effective [January] 1997, but in
terms of operationally reporting it to EIA, we just got around to
it April 1 of this year," said ANR spokesman Joe Martucci.
One other storage change that's likely to occur in Michigan and
affect EIA's statistics this summer is the introduction of the
Washington 10 storage field in Macomb County. The new field, which
is owned and operated by MCN, started injecting gas in April and
has 41.6 Bcf of working gas capacity and 400 MMcf/d of
