Drilling in the Jonah field has shown the least amount of negative seasonal fluctuations, increasing by large percentages during the winters of 1997, 2001, 2003, 2004, 2005, and 2006.
In the winter of 2006, Jonah drilling activity increased by about 63% from the summer before. Due to seasonal restrictions on drilling in the nearby Pinedale Anticline
, it appears that many Anticline rigs migrate to Jonah during the winter months.
