The Michigan Geological Repository for Research and Education at Western Michigan University archives analytical, pressure and production data from oil and gas wells. Most of this data was donated in paper form which we have converted to digital format.
Michigan oil and gas well gas analysis data
This spreadsheet contains analytical data on natural gas sample compositions from nearly 1200 wells. Data include county, well name, permit, gas gravity and molecular composition percentages of methane through heptane. Also noted are oxygen, carbon dioxide and hydrogen sulfide content. These data were validated, modified and updated by Joe Hatch of the United States Geological Survey as part of their work concerning Michigan Basin petroleum assessment.

Michigan oil and gas well bottomhole pressure data
This spreadsheet documents 193 wells with Michigan bottomhole pressure test analyses. Data include county, well name, permit number, test date, depth and pressure (many wells have multiple measurements in the borehole).
Michigan oil and gas well multipoint backpressure testing data
This spreadsheet documents more than 70 well multipoint backpressure test analyses. Data include county, well name, permit number, field name, reservoir formation, reservoir temp (oF), temp depth (ft), gas gravity (Gg), percentage of CO2, percentage of N2, percentage of H2S and AOF rate.
Michigan oil and gas well production testing data
This spreadsheet documents more than 550 well production test analyses. Data include county, well name, permit number, gas to oil ratio and gas gravity.
Michigan oil and gas well production database
Wellogic, the state of Michigan's groundwater database, is a searchable online listing of Michigan oil and gas wells and fields.
