There were 47 vertical wells at Selmo of which 22 are still producing.- when IPM took over. The noteable result since is Selmo 41, a straight sidetrack from a previously collapsed well drilled in 2003 then at 120 bopd and now reclassified as "new" production at 100 bopd.
Point is the hype of the horizontal revisit used in the initial IPO has not exactly been a screaming success.
Looking at Selmo 22 with its heel / toe and multi zone water problems, much the same could have been gained from a straight side track and another vertical well 600 feet away. It seems easier to drill, isolate and produce.
Some big blob fields may be suited for horizontal, but complex little ones less so.
Since Mobil started way back in 1964 at Selmo, even basic revisits of closed in wells may revive production. The oil found its way there in the first place and a shut in may have allowed much to seep back - especially with only 16% recovery rate.
I recon pack away all the expensive horizontal gear and have a program of straight sidetrack revisits, keeping it simple for the local staff. Maybe throw in a few new verticals. The results are what should guide them, not technical ego or inertia of past investment.
