Deep Tight Gas

[Bilal Amjad]

How deeper tight gas zones are different as compared to shallow ones, in terms of analysis and simulation?

from my experience they tend to be naturally fractured.
from simulation point of view, compressibility factors are quite low and therefore most of the driving mechanism is rock compresiblity.
operationally fracturing operations are very difficult, acid stimulation sometimes works. but you would need long times to clean the formation in excess of 6 months. these were my observations...

THANKS, it answered.
