It does appear that Surge believes Madison/Mission Canyon may be a second target from the Spearfish. Even though NDIC names the Spearfish to be Spearfish Madison, the drilling lands in the Spearfish on the 15 or so wells that EOG, Corinthian and Legacy have drilled since horiz drilling started in 2009 in Bottineau County. Most of the older wells in this area of ND targeted the Madison using vert drilling. These are now stripper or abandoned. It will be interesting to find out more about the Mission Canyon hearings as these are right in the middle of what has been for the last 3 years an attempt to establish a Spearfish play. If the objective is Mission Canyon, then these two wells will be slightly deeper as the Spearfish overlays the Madison in this area. It will also will be interesting to find out if horiz Madison is the objective. Sure seems as tho Surge saw something on the seismic in mc and want a closer look.

This is a PDF of a study comparing fracking long and short laterals in the Canadian Bakken just north of North Dakota.
I'm attaching a Spearfish label even though this has to do with the Bakken.
My interest in this is piqued by the recent acquisition of the Ritchie Bottineau Spearfish wells by Surge Energy/Corinthian Energy. According to Surge Energy's March 8, 2011, corporate presentation, slide 7, Surge Energy has drilled approximately 100 horizontal wells in the Canadian Spearfish between January, 2008, and April, 2010.
On slide 15 of that presentation, it is noted that Surge has drilled five (5) horizontal Spearfish wells just on the other side of the North Dakota border. It is costing them $1.2 million to drill a well, compared to $6 - 8 million for a typical North Dakota Bakken well.
Based on the well file reports and the GIS map server it appears the two Bernstein Spearfish wells were simply fracked vertical wells. Surge's core competency is horizontal fracturing of the Spearfish and it's very likely that Surge will go back into the Bottineau Spearfish wells and put in horizontal laterals.
