Hi Brom, in my view in any well communication to another zone is always bad news as will cause pressure loss, the frack invaded the other zone, there was no block/seal between them, can’t remember if they fracked the both the perforations together or there was a brigde plug involved, the change from horizontal to vertical was to save money as it was an appraisal well, vertical wells seam the choice of company’s looking to get the application right of removing oil, as we know production wells are more commonly horizontal wells if there is more of an economic case with one much better producing formations, if there is more potential in each many formation then a stacked play could be economically viable then vertical the choice!
Probably know this already anyhow! :/)
