Art- I tried to explain this elsewhere(see post #8411 above). The height of the gas column is the “vertical” height/distance above the gas/water contact. For that part of the field where the bottom of the carbonate is above the gas/water contact the “thickness” of the gas column in a particular well is limited to the thickness of the pay zone (carbonate) but the height of the gas column in a particular well is the vertical distance from the top of the zone to the gas/water contact.
