Long Laterals vs Short Laterals in the North Dakota Bakken

There's a nice discussion comparing the effectiveness of long laterals vs short laterals in the Bakken at this link.

The suggestion that there might be a significant heel-to-toe disparity could result in a change in drilling strategies.

The heel-to-toe disparity: significant more oil being produced from the heel of the horizontal compared to the toe. The heel is near the "kick-off" point of the horizontal, where the horizontal leg leaves the vertical segment.
