This study assesses midstream natural gas infrastructure needs through 2035 and includes an extensive update of natural gas, natural gas liquids (NGL) and oil production trends based on projections of drilling activity, the recoverable resource base and prevailing market conditions. A new methodology has been employed to estimate better the amount of new well connection, gathering system and gas processing plant capacity that will be needed over time. With extensive upstream development occurring outside traditional, conventional-gas supply regions that generally are well served by existing pipelines, new midstream natural gas infrastructure represents a critical link that will benefit both natural gas producers and consumers.
