Assessment of so2

Assessment of so2

Mar 18, 2020The U.S. Geological Survey has developed a new assessment method to estimate how much oil and gas could be produced by injecting carbon dioxide into petroleum reservoirs. The methodology also includes a way to estimate the amount of carbon dioxide remaining in the reservoir after the production of oil and gas is complete. Using injected carbon dioxide to stimulate oil and gas

  • Volcano Watch — New assessment of Kīlauea’s extreme SO2

    To measure SO 2 emission rates, volcanologists use a device called a spectrometer. The instrument is mounted to a vehicle or aircraft, which passes under the SO 2 plume and measures absorption of sunlight by SO 2 overhead. The more SO 2, the less ultraviolet (UV) light that reaches the spectrometer.
