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
