I have been looking in the docs again, the seal stuff is still a bit difficult especially when discussing the faults because I always think of them as giant cracks, which is probably incorrect.. but I am confident this will turn out good,,
like you mentioned, DM said the other fields Eyasi and Balangida have sub-surface salt horizons being salt lake beds, grade A seals, thats plan B.. Balangida also has 10% seeps.. So plan B sounds a winner too..
Rukwa has salt as they farm it there, but not seen much of a mention of salt seals, but still lots of pages to read,.
I read something about erosion of the lake bed..something that happened long ago..
It has shale but it is dispersed, also tuff beds(layers of melted volcanic ash) in the lake bed formation which is a good seal. The report explains that the seeps could charge nearby sealed traps.. That makes me think of Itumbula with its springs.
Seals are also present within and at the top of the Karoo section
The karoo section is the probably the third target of each of the wells as its below the lake bed..maybe the 2nd too, I need to read more.
Based on your comments and my reading so far it sounds really promising..
What fills me with extra confidence is they call Rukwa the Goldilocks Zone, and DM almost laughed when asked about finding dust,,,,
