The MCGL Digital Library has been many years in the making.  Our objective is to provide anyone working Oklahoma geology access to our data via desktop computer or portable tablet/phone. Our mission is to preserve, archive and disseminate this valuable and irreplaceable geological data.

The MCGL Digital Library is being continuously updated with newly-scanned historical data sourced from the MCGL paper library plus new well logs filed with the Oklahoma Corporation Commission by operators and subsequently released to the public as required by statute.

Digital Library subscriptions/memberships are now available.

In addition, to add to and maintain this site, as a 501(c)3 non-profit entity, the MCGL is seeking financial donations (tax-deductible) which can be dedicated to continued scanning and indexing activity as well as for any specific scanning project selected by a donor.

For further information on how you can help get all of our historical data (including special collections) scanned and indexed, please call us today at 405-235-3648.
