The above link is a lease/ sale map (pipelines). You can right click and zoom on an area to see the details of the lease blocks. This information is probably not too useful unless you know what you are looking at, except that it shows the areas of lease and how far out, etc.

This map is kinda useful as you can zoom in on specific regions. It shows gas pipelines, oil pipelines, oil fields and gas fields as well as identifying rigs. It is insane!
