the 15-20 cents you refer will be paid via capital...

the 15-20 cents you refer will be paid via capital repayments...i think you may be very conservative as to the reserves,and your oil price average over the life of reserves,(which are in question.i.e much greater,on both counts)
that is why this is so brilliant...capital evenly distributed,without having to sell...your return comes from the sum of the capital repayments...so all shareholders will hold until the last payment and reserves expunged.....and no acquisitions...because those costs will impede your repayments,and management won't have a reason to retain capital.
NET RESULT...20 c plus per share +( subject to volume and average oil price )
