RE: RE: RE: Updated calculation of East OlimtoiUsually you just perforate the sands, if the gun is 30ft, you can imagine that there will be quite a few runs if you want to shoot the whole 160m...
In theory, the PI (productivity index) doesn't differenciate between 10 zones of 1 m, or 1 zone of 10m. However, thin zones also often mean bad (i.e low poro/perm) zones with limited lateral extention. If you look at the log in the presentation, it does look like there are some pretty clean sections at the top, around where they got the kick. A kick in itself doesn't have to mean thick and permeable zones, the volume in the wellbore is quite limited. But sure, a 20 ft section would of course be able to flow basically 20x more than a 1ft pay zone (which should not be considered a pay zone, you would hardly see it on the log...)
The high pressure is however a very positive thing, because if the permeability is on the low side (i.e 50-100mD), having a high reservoir pressure will mean being able to produce with a higher drawdown (difference in pressure between the average reservoir pressure and the flowing bottom hole pressure) and hence get a higher rate.
Hopefully they have not damaged the zone too much with the drilling mud (as in AKD-03), but it is a risk.
Hope it helped.
