Good info zguy - no doubt there are special procedures in place on this well to get the oil production flowing. The gas and associated condensate makes for a complicated completion in lieu of the fact there is not a local market at present for the NG. It is a shame to have to vent / flare that gas but it's the cost of doing business if we want to produce the liquids.

I don't mean to beat a dead horse with this lingering topic, I just want to express my reluctance to believe the original PR stating 2000-2500# of pressure in this zone. Below is a link to a pressure gradient chart that shows formation pressure versus depth. This includes normal hydrostatic, overpressure and lithostatic gradient lines. If we assume the Squirrel zone is around 900', normal virgin pressure would be around 500# - the same as KAA mentioned for a typical KS well at this depth.

This will be my last post on this topic, I will just wait for the final well results to play out and see if any further mention of formation pressures get released. Once they market the gas, it's normal for the production figures to list a volume (mcf) and flowing/shut in pressures. Time will tell...
