For newbies, one of the best sites to locate rigs and wells in North Dakota is "MagicMaps." It has been linked at my "Data Links" pay for quite some time.
Great news! The developer of MagicMaps says in the very near future, the site will also map wells and rigs in Montana.
In addition, MagicMaps will tie production to the mapped wells. This is a huge update, giving a lot more Montana information for readers of this blog who have been looking for more Montana information.
Without the updates, MagicMaps is ... well ... magic. With the updates, even more magical. I've added the link to the sidebar at the right ... near the top.
