Hydrocarbon exploration and production activities, including seismic operations, emit significant quantities of greenhouse gases (GHGs). These gases, which occur in the earth's atmosphere, absorb and reemit infrared radiation, and are a product of both natural and human-influenced processes. The major GHG is water vapor. Other primary GHGs include carbon dioxide (CO2), nitrous oxides (N2O), methane, ozone (O3) and chlorofluorocarbons. Recently, higher concentrations of CO2 in the atmosphere have been associated with human activity, and linked with climate change that has occurred due to rising earth temperature. In view of widespread concern over the...
