The optional $45m acreage option has to be purchased 6 months after the first well is drilled or 12 months from the original purchase date ... so they have plenty of time..

But that implies that dont have better options and they may also choose to move earlier to include any results in the January reserves report... But best to drill the acres before moving on them..

As for the $20m tax implication from the sale proceeds im not sure on a date that has to be action'ed or lost.. with residential property its within 60 days.. but I have no idea how its applied in this case. IRS section 1031 exchange...for properties of like kind... in that case its possibly past, but there may be different rules of for this type of property.
