I was always puzzled, as to how they could achieve the shattering of the shale, with the tempestites acting as something of a cushion interfering with normal crack progression
Looking at the new frack plan
Doing the stimulation as one single step, with a multi perforation cluster stimulation, will simultaneously introduce fractures and pressure across the entire zone. This should both support the reservoir structure and shatter at the same time, they have the ability to target zones with fractures both sides of the larger tempestites. Clever people I think

Turn this picture of a horizontal cluster simulation to vertical in your head, then you should be able to envision what is going to happen. Dismiss the spacing 88e will have their own plan
