Senegal wants this sorted ASAP, page-88

If you look at the first 6 months of 2016 as a bit of a guide it looks like they used $26-28M cash per quarter when drilling. Costs are coming down however.

In most recent "investor presentation" they say "Funded through 16/17 firm work program" which IMO implies they need funding beyond that. They do as you observe have farm-in option if they move on the Djiffere opportunity but timing will be important.

Given costs are coming down lets say $20M per drilling quarter through to 1q 2017. Plus say $ 5M for the most recent qtr where they weren't drilling.

That leaves $20M cash to do the PE and drill one well in Djiffere by the end of 1q 2017. Subject to possible sugar daddies at SNE and farm in partner in Djiffere which are unknown in terms of existence in the former case and timing in the second. If they announce they are going to drill Djiffere and can sort out transaction completion on Djiffere Farm-in before June 2017 all is well and they might avoid a CR in 2017.
