Natural Gas Reserves

There are terms often used to express the natural gas reserves are: proven reserves Proved Reserves and Reserve underlying Potential Reserves.

Proven reserves Proved Reserves is those quantities of gas to be found during the excavations, and can be ascertained through the properties of reservoir such as production data, pressure relationships and some other data, so the volume of gas is determined with reasonable accuracy to some extent.

Latent Reserve is those quantities of natural gas that are believed to exist in many crystal rocks, but did not dig so far. It will be quantities processed in the future after the end of proven reserves.

Were followers are many ways to estimate the quantities of natural gas reserves, including dependence on production rates previous exploratory wells and experimental methods and mathematical equations, are also used method of estimating gas future through the amount of oil explorer, or volumetric estimation method for potential gas reserves.

There has always been a disparity in the (proven reserves) and (latent Reserve) even in the case of producing fields in the United States, where, depending on the sources of information, estimates of reserves remaining passive ranging between 650 -5000 Tcf , The Reserve Certainly in 2000 it was one thousand and fifty Tcf in the United States and 170 Tcf in Canada

and unlike oil reservoirs where there is 80% of them in the OPEC countries, most of natural gas deposits exist in the former Soviet Union, the Middle East, Near East, Africa, North America, Central and South America, and Europe.

According to a survey conducted by Energy Information Administration in the year 2006 were estimated figures for reserves proven natural gas as follows:

  1. Russia 1, 688 TCF .

  2. Iran 944 TCF.

  3. Qatar 910 TCF .

  4. Saudi Arabia 244 TCF .

  5. United Arab Emirates 213 TCF .

  6. United States 193 TCF.

  7. Nigeria 185 TCF .

  8. Algeria 162 TCF .

  9. Venezuela 152 TCF .

 10. Iraq one hundred and twelve TCF .     

Gazprom Russian about a third of natural gas reserves and produces about 80% of Russian natural gas, and runs this company 43 station CBS Compressor Station and about 155 thousand km of natural gas pipelines, Russia is the largest producer and exporter and consumer of natural gas, producing about twenty-one Tcf annually consume them 14.5 Tcf and exports the rest.

While Qatar is a pioneer also in the natural gas reserves, and equally so with Iran almost as owns giant North Field, Iran It has Pars gas field east which is located on the borders of Qatar.
