Product Description
This presentation focuses on the greenhouse gases from the extraction, processing, and delivery of natural gas and the key variables that affect the results. It includes eight distinct sources of natural gas and performs a number of sensitivity studies. The production rate of natural gas wells, episodic emission factors and the flaring rate have the most impact on the cradle-to-gate emissions profile, while power plant heat rate or efficiency most affects the cradle-to-grave emissions. New Source Performance Standards have recently focused on the oil and gas sector and could be effective at reducing the upstream emissions from natural gas systems.
