One question keeps nagging at me with regard to NZ.
If they shut in the existing low producing well/s because they were
uneconomic given the collapse in the POO...Why then would they want
to spend more funds chasing a similar resource when the price of oil
has not recovered?
How is this going to be an ongoing source of funds for the company when it
costs more to extract than it makes?

Something doesn't add up..or am I missing something?
