Conventional Natural Gas Megan Molnar and Maggie Meyer

Definition  Conventional oil and gas apply to those of which can be extracted after drilling by the natural well pressure and by compression or pumping operations.

Machine Process  Wells are utilized in order to extract the natural gas as well as oil. The gas sits above the oil, which is removed through a process involving wells. However, the well’s natural pressure might be too low to produce large quantities of the oil and gas.  Water and gas injection or depletion compression can also be used, but wells are most common.

Net Energy Outcome  Net energy represents the usable amount of HQE available from a given quantity of an energy resource.  Conventional Natural Gas has a high net energy yield.

Liquefied Natural Gas (LNG)  Natural, conventional gas is converted into LNG at a high pressure at a very low temperature  Highly flammable  Distributed by pipelines  Transported overseas in refrigerated tanker ships

Advantages vs. Disadvantages Advantages: 1. Ample supplies available 2. High net energy yield 3. Emits less carbon dioxide Disadvantages: 1. Low net yield for LNG (liquefied natural gas) 2. Releases carbon dioxide 3. Difficult and costly transportation

Negative Environmental Effect  The drilling process takes a while and disturbs quite a bit of land and water resources.

Energy Source Availability  Readily available in the majority of countries, although it is diminishing.

Leading Producing Nations 1. Russia 2. Iran 3. Qatar 4. Turkmenistan 5. Saudi Arabia

Russia  Largest natural gas reserves in the nation  Oil and gas revenues account for more than 50% of the nation’s monetary supply

Estimated Depletion Time  According to AAPG … The World: years The United States: years  According to ASPO USA … The World: 8.9% The United States: 6.1%
