Would it be surprising if a company had been willing to carry ERHE's costs to full oil and pay the other expenses up to that stage to get let's say 25% of the 60% if there is supposed to be $ 3 billion barrels of oil in the block? 25% of three billion barrels is 750 million barrels. Assuming a price in the ground of $ 10 per barrel the value for 25% would be $ 7.5 billion dollars. Even if the chance of finding that oil had been less than 50% it would seem to have been an attractive proposition to foot the bill for ERHE's stage up to first oil.
