The Hess EN-Weyrauch Wells

These Weyrauch wells are on multiple pads in different drilling units; later, I will separate them by pads.

Proposals for some of the Weyrauch wells suggested stacked laterals: one lateral in the middle Bakken and one lateral in the Three Forks. This is not the first time I have seen such proposals, but it is the first time I have posted a schematic (August 18, 2014); I think Slawson and/or CLR might be doing something like this in Montana. It appears that as of August, 2014, only one horizontal had been drilled. Here is an example of stacked lateral proposal (this was for #19621, but was similar to at least two other proposed well -- see above):
