Geographic data is strictly land based searches. This is a very popular filter type as it gives users a variety of options for searching for wells.
One common request and need is to search by township/section/range and survey & abstract data. The Land Grid option allows that.
You can also search by Plays and Basins. These search for wells that fall in the geographical boundary of a play. See below for an example and see more about the geographic boundaries here.
And finally you can search by area of interest and make custom shapes. Learn more about how to search with an AOI filter here.
