JPR were on the brink of signing up for 100% of the adjacent NWZ proven oil field as per ASX release 1st Sep 2008,

Jupiter renegotiates purchase of 100% of North West Zhetybai oilfield.

In part:

x Jupiter has agreed new terms with vendor based on an initial
payment of $US17m with $US12m due on completion and a
2nd deferred payment of $US5m.
x Final payment will be based on proven (1P) oil reserves
identified x $US5 per barrel with the maximum price of the
field capped at a valuation based on 1P reserves of 12
mmbbls.
x Field must have minimum 1P reserves of 4.5 mmbbls in order
for vendor to earn more than the initial $US17m payment.

and, on 12 August 2008:

x Macquarie Bank has agreed indicative terms to provide a debt package to support the acquisition and JPR is confident of finalising an equity raising to complete the total financing of the transaction.
x Purchase price range is set between $US5 and $US8.67 per
barrel of proven (1P) oil reserves with the maximum price of
field capped at a valuation based on 1P reserves of 10
mmbbls.

If JR resurrect this deal, now the GFC is behind us, then my thoughts are that it would be beneficial to JPR without share dilution.

You cannot have enough oil reserves if the price is right and the price of oil continues to rise.
