DrillingInfo ALWAYS saves your last run search.
You can access your previously run search by going to the "Re-Use My Last Search" section on the Search Wizard home page. The "Execute" options will re-run your search and take you to the results page (map or table). The "Use the Parameters from your Last Search" link will apply your search parameters and allow you to review or edit them via the Search Wizard and criteria pages.
You can also access your last search by going to the "My Saved Searches" section on the Search Wizard home page or in the My DI section. Once you have accessed the "My Saved Searches" page select the search "My Last Search."
The saved search called "My Last Search" is always the last search you ran on your account.
