Sublette County Rig Count:
Up, Up, and now down?

As of January 1st, 2008, there are about
44 drilling rigs operating in Sublette
County
.

This corresponds to about the same
number of  rigs drilling at this time last
year, which remains the all-time high for
winter activity.  However,  the summer of
2007 saw a smaller spike in activity then
the summer of 2006.
----------------------------------------------------------

A winter drilling pilot program on the
Pinedale Anticline, as well as increased
activity on the non-restricted
Jonah Field
has contributed to the new all-time winter
highs.  The Anticline had an average of
about 23 rigs this winter, while Jonah
increased to about 15.

The number of drilling rigs active in the
area has a direct and immediate effect on
the workforce population in Sublette
County. At any given time, each drilling rig
requires a direct
workforce of about 22
people, the vast majority of whom are
"non-residents" of the area. When the  
weekly rotations of the workforce are tallied,
about 44 different individuals are dedicated
to each rig.  Scores of additional workers
are also needed to provide support and
services to the rigs.

Seasonal Fluctuations:
With the added winter activity, the 2006 winter drilling fluctuation was among the lowest on record. The number of rigs
dropped by about 3 this winter, or about 7%. As a percentage of the overall total, the seasonal fluctuations have been
decreasing gradually since 2002.  The drop in the actual number of rigs has been increasing since 2003, although it
dropped substantially this past winter.

Fluctuations are expected to decrease in the coming years as winter drilling in the
Pinedale Anticline continues to expand
and activity increases in the
Jonah Field increases under the Jonah Infill Project.
