extra equity

I'm trying to get a handle on when this equity decision is due. The 13 3/8" casing is put down just above where they think the first oil trap is. Makes sense. Given the estimate to drill 2130 mtrs and evaluate in 20 days , let's assume 2 days to evaluate that makes 18 days drilling. 118mtrs a day. From what I can gather the first trap is around 1500mtrs. On my calculation Phil may have another 12 days to make a decision and announce. All the above is my opinion only and may be way off but would love someone to give a more educated assesment. cheers
