Ann: Webinar for Block 9 Update, page-150

Thx for posting. Very useful interp and summary of the presentation.

On a technical note. I cringe when I see co-mingled flow over wide, '00m intervals in fractured rock reservoirs. Fractured rock reservoirs are pretty complex when it comes to flow paths, interconnectivity of fractures, and anisotropy. My view is pick the best fractures, set packers and separately test each of the discrete zones (10's of metres) identified in wireline logs and drilling/mud log observations.

They already told us the flow measuring devices in Amistad 1 indicated most of the 1200 bopd flow was coming from the cement impacted fractures at 980m. My thoughts are, given they already have cement behind the casing in this well, they should isolate the 980 m interval and frac that and see what comes out once they've blown away the cement in the reservoir. Like you, I can also see the flow rate multiplying from this zone once they've blown away the cement that was not meant to be there. They also need to get on top of what happened during the casing operation in Amistad 1 - how did the casing guys get it so wrong (hundreds of metres of extra cement behind casing).
