Counts

The counts were generated on Jan 22, 2009 and will give you a general idea of what kind of wells and how many we have in Michigan. The totals change from day to day as new wells and drilled and old ones plugged. These counts do not include mineral wells or wells that were drilled before permits were first issued in 1927. The grand total is higher than the number of permits issued in Michigan because of kicks, sometimes a well has several directional kicks from one hole, and so the same permit number gets counted more than once. These counts reflect API numbers, not permit numbers.
