Again, people are imagining the naive drinking straw model. If you want to get oil out of the ground it has to be pressurised which can occur either naturally or artificially. In addition to hydrostatic pressure there may be a water drive from below, a gas cap drive from above, or artificial injection. A gas cap will form in an updip if the oil pressure is lower than the bubble point pressure. This gas cap represents FREE ENERGY for well pressurisation. There is also gas in solution in the oil which will separate out when the oil is extracted. You have to do something with this, which is often to inject it back down into the gas cap to maintain pressure. Remember, the oil is worth four times as much as the gas and artificial well pressurisation is going to cost you money eventually. Why, then, would you get rid of the gas cap that nature has provided? The quantity of the gas, the market for it, and the possibly free Kinsale infrastructure MIGHT make a difference ... and then again it might not. It's not something that armchair oil experts are going to figure out. And I suspect the Providence bosses don't know in advance either as they haven't told us about any detailed reanalysis.
