Slide 7: Compare the two maps of oil and gas well drilling (above) which shows spatial changes in production from the 1900-1930 period as compared to the the 1990s. You will see that the number of fields and wells have increased, but so have the number of "dry" wells. You can learn much more from the Digital Petroleum Atlas by the Kansas Geological Society. See the "US Oil History" online visualization--a Quicktime Movie of maps from 1900-1990. Credit: Courtesy Kansas Geological Survey/ Digital Petroleum Atlas. |
