This was actually the second result from the Oligocene. There was an earlier test across the gas/oil interface. Of course the high pressure gas flowed much more easily than the oil, which as I recall flowed somewhere between 900 and 1400 BOD. So there will be in total 4 tests, 2 having been completed already. The first test is not indicative of the actual volume of oil or its pressure but it does give a reference point for the top of the oil and some indication as to the amount of gas. From my understanding it is a significant gas cap. More than likely this gas cannot be produced until the oil has been depleted. 

Because of the amount of gas which may be present in Kurdistan, it threatens to displace Russian gas in Turkey. This may be one reason Gazprom has chosen to participate. If they cannot sell as much gas from the Russia perhaps they can sell it from Kurdistan.
