According to government/industry statistics, proved reserves of oil and natural gas have increase substantially in 2012. Newly proven national petroleum geological reserves are 15.2 million tons, a year-on-year growth of 13%, which is the tenth time of more than 1 billion tons since the founding of People＇s Republic of China; newly proven technically recoverable reserves are 270 million tons, a year-on-year growth of 7%. The 2012 national newly proved reserves from natural gas exploration are 961.22 billion cubic meters, a year-on-year growth of 33%, which is the highest level in our history; the new proven technically recoverable reserves are 500.8 billion cubic meters, a year-on-year growth of 36%. National natural gas production was 106.76 billion cubic meters, a year-on-year growth of 5.4%. The Ordos, Tarim and Sichuan basins are still the main producing areas of natural gas in China. In 2012, national oil production was 205 million tons, a year-on-year growth of 1%, which made a steady increase. The national coal-bed methane production was 2.57 billion cubic meters, a year-on-year growth of 24%.展开更多

After analyzing the development of 3-D geoscience modeling technology （3-D GMT）, this paper discusses the application of 3-D GMT for the estimation of solid mineral reserves, emphatically introducing its workflow and two key technologies, 3-D orebody surface modeling, and property modeling. Moreover, the paper analyzes the limitations of traditional methods, such as the section method and geological block method, and points out the advantages of 3-D GMT： building more accurate 3-D orebody models, expressing the internal inhomogeneous attributes of an orebody, reducing the potential for errors in the estimation of reserves, and implementing dynamic estimations of reserves.展开更多

Great variety, mostly industrial and metallic minerals, and energy mineral raw materials such as lignite, are in its subsoil. The probable and proven reserves of most of the mineral resources of Greece are unknown, as detailed investigations （e.g., drillings, measurements, analyses, etc.） are lacking. In our assessment the total value of the reserves is about ε1.5 trillion and is four times its total debt （ε360 billion）. The total value of the indicated reserves of the Industrial Minerals ＆ Rocks is ε60 billion. The total value of the indicated reserves of the Metallic Minerals is ε72 billion. The total value of the indicated reserves of the Energy Mineral Raw Materials is ε1,362 billion, of which ε268 billion belong to the lignites which are exploited for decades to produce only electricity. The indicated oil reserves are 10 billion barrels with current value of E685 billion and the corresponding of natural gas 3.5 trillion m3 with current value of ε409 billion.展开更多
