Drilling in the PAPA
As of January 1, 2008, there are about 28 drilling rigs working in the Pinedale Anticline Project Area (PAPA), this is about the same level of drilling as this time at the beginning of 2007. In the summer months of 2007, the PAPA averaged about 30 rigs working at a time.
The number of rigs working in the PAPA have increased almost exponentially between 2000 and 2005, with large seasonal fluctuations. Since then, the growth has leveled somewhat and restrictions on winter drilling have been lifted in some cases.
The average drilling time in the PAPA is about 40 days, as the average depth of the wells is about 13,000 - 15,000 feet. In addition, a number of the wells are directionally drilled, also adding to the drilling time and ultimate workforce requirements.
