baragatan-1 well to be re-spudded nido petrole, page-31

Oracle

Baragatan-1 is not exactly a wildcat. Exploration has already been done on this reservoir with encouraging results. What you appear to be concerned with can be dismissed with those results. You may be alluding to a "spill point" or leak in the seal caused by a fault which decreases reservoir size (that would have been examined in exploration results).

This is still an exploration well so there is still risks.

Plenty on the net regarding structural traps which are the dominant type of reservoir (faulted traps included in this category).
