Please note: Due to incomplete latitude and longitude coordinates not all wells will be displayed using the Map-Based search. Please use the Text-Based search to find and display all records including those lacking the lat/long coordinates. Also please note that the coordinates provided are only estimates. The coordinate source column identifies the source for the lat long values. For values obtained from state records please check with the state for more information about how the values were derived. Additional coordinates will be provided as they become available.
