A History of Horizontal Drilling in the Tyler Formation -- Williston Basin, North Dakota, USA

At the link, click on the second story from the top at the right: a history of horizontal drilling in the Tyler Formation in the Williston Basin, North Dakota.

Talk about perfect timing, and a huge thank you to Don for sending me this link. I would have missed it.

It's perfect timing because I've been blogging about the Tyler off and on over the past few weeks.
