Ann: Drilling update at Alameda-1 - Significant Oil Interval, page-282

Hi batman13,

MAY are probably just including the N Structure's NW Block in their Alameda drilling resource estimate due to the potential that the N Structure's internal thrust fault is sealing and thus the SW Block will require an appraisal well - albeit obviously if NW Block is a success then the SW Block becomes IMO very low risk.

IMO two sealing models potentially exist for the "Greater" N Structure, on the basis of the oil shows in Alameda-1 translating to reservoired oil, one being the Model below and the second having the SW Block's SW thrust fault sealing - I'll post on this later today.

In relation to your query on the N Structure's SW Block and the Zapato structure - I would say no - the key for the N Structure's SW Block's contingent resource position solely lies with what happens in the N Structure's NW Block

Hope this helps.

Cheers
