“…In addition, The Academies of Medicine, Engineering, and Science in Texas (TAMEST) published a report that estimated the number of trucks required for hauling equipment, materials, and fluids for Barnett shale development wells at 988 per well. If on average each loaded truck travels 500 miles with maximum allowable load in Texas giving a load factor of 2.3, and using 1000 total trucks, and multiplying by the GREET program estimate of 23. 5 MJ/mi for heavy duty trucks using diesel fuel gives a total of ∼27 MMscf (million standard cubic feet) equivalent energy use. With production from a typical Barnett shale gas well at ∼5 Bcf (billion cubic feet), the energy required to power drilling, stimulation, and production operations for shale gas represents a negligible fraction of the energy content in the produced gas.…”
