Sounds excellent reading it but those deep wells normally give BIG problems getting to it.
For those who need some more info on that have a look at Santos and the Jeruk discovery of Madura island in Indonesia.
It supposed to be a company making oil find with millions of barrels of oil. It has become a miserable excersise very costly and no oil that can be sold so far.
Deep wells need deep pockets and oil estimates are hard to guess the deeper the wells.
