1.5 million per hole. If you go lateral double to triple that figure. If you fracture even more. And that is just the initial cost depends of the life of well ...if you need work overs there are at 120-150 K per shot. The overall cost of infrastructure like gathering systems,roads,water disposal,dams and power supply are around 100k per well including maintaining and royalties.
After you get the gas to the nodes you have a multimillion compressor station and then finally the pipeline to the consumer. A lot of money if you don't have 50% of good producing wells you loosing hand over fist and don't forget the lifespan of only 15 years for most wells.
