Gerald, you can get a subscription to the website, Drillinginfo which is not cheap.  Or you can order a Tobin map from P-2 Energy Solutions in paper or digital format.  Be sure to check on both sources to see when they were last updated for your area of interest.  I am replying here on your personal page as it is against the site rules to openly promote companies and websites that are not advertisers.  Good Luck.
