Ann: Alameda-1 Drilling Update, page-109

Actually MAY retains 30%, but incurs 15% of costs.
As VOGC has indicated the schematic is designed to provide a visual of the various features/structures rather than being a true indication of depth. And bear in mind the hole wasn't drilled vertical, it was inclined from spud in order to encounter the targeted areas that don't lie on the 1 plane.
The main targets are well below the current depth from my understanding. Whilst there's never a guarantee I plan to hold for those deeper targets, the shallower zone is interesting but it's not the real zone of interest - but if the wireline indicates otherwise then it's a bonus.
