The Michigan Public Service Commission issues wellhead connection permits for gas wells, thereby giving authority to produce gas into a pipeline. This authority is granted under 1929 PA 9. The MPSC has jurisdiction over the production of gas wells only. (The Office of Geological Survey in the Department of Environmental Quality (DEQ) has jurisdiction over the production from oil wells, although the casinghead gas production from oil wells is reported to the MPSC.) The first permit was issued in 1935 and over the next 49-year period ending in 1983, 2192 permits were issued. This contrasts with over 10000 permits issued in the 24 years since. This increase is due to the discovery of the Antrim play which blankets a large portion of the northern lower peninsula of Michigan.

Key to Formations
Antrim	The Antrim formation is a shallow gas-producing reservoir which is productive across the upper part of the lower peninsula of Michigan. This play became active in the late 1980's and infill drilling continues to be strong. In 1999, Antrim gas production accounted for 74% of the total natural gas production in Michigan.
PdC	The Prairie du Chien (PdC) sandstone is geologically the oldest and deepest gas producing formation in Michigan and is productive over the central portion of the lower peninsula of Michigan. The PdC play was most active during the mid 1980's to early 1990's.
Niagaran	The pinnacle reef production in the Niagaran formation occurs over two bands in the lower peninsula of Michigan. These bands or trends are commonly referred to as Northern Trend and the Southern Trend. Drilling was most active in the mid 1970's to late 1980's.
Other	Refers to wells permitted in all other formations, including 2004 production from the Michigan Stray (4 wells), Reed City Dolomite (3 wells).
