The HorseShoe coals of Alberta (Canada) were extremely low pressure, at time 60 psi (413 kPa) lower.
In this scenario, TEC used very low wellhead pressure through wellhead “POD” system compression. As shown in the second plot, the gas rates at an individual well could reach nearly 1 MMscf/d due to the effects of permeability growth (I.e. Matrix Shrinkage)
