Downhole Stratigraphic and Geophysical Logs in Missouri
The Missouri Geological Survey is responsible for the collection and archival of stratigraphic and geophysical downhole information relating to oil and gas wells in Missouri. The stratigraphic and geophysical log map-based interface represents a complete historical accumulation of stratigraphic and geophysical downhole information collected by the Survey, excluding the information contained in the Logmain database. Although the majority of information was acquired from boreholes associated with the oil and gas industry, boreholes related to other sources are represented.
The history of Missouri’s petroleum industry has been of limited production. However, some believe Missouri may possess significant untapped oil and gas resources with an estimated economic value of hundreds of billions of dollars. Rising oil prices and the uncertainty associated with foreign supplies have created rising interest in Missouri’s oil and gas resources.

Downhole Stratigraphic and Geophysical Logs
The map-based interface contains approximately 4,100 individual logs. The oldest information available is from 1939, representing approximately 75 years of stratigraphic and geophysical downhole information. Users of this interface are accessing the same stratigraphic and geophysical downhole information accessible to MGS staff. Additionally, visitors may locate oil and gas permits by accessing this map-based interface.
