Print this pageAbstract: Evaluation of Junggar Basin in China
Joe G. Zhou
Junggar basin lies in the northwestern comer of China and has an area of about 130,000 km2, in a compression tectonic regime, with about 14 suites of source-reservoir-seal assemblages developed from Carboniferous to Eogene.
It is a prolific basin with a total hydrocarbon generation of 266.9 billion tons, an upside oil potential of 6.937 billion tons and a gas potential of 1,228.9 billion m3. Due to its tuff surface conditions and remoteness, the exploration level is still very low: the proven geological reserve was calculated; the cumulative oil production was 0.123599434 billion tons by year-end 1994. There will be about 5.4 billion tons of oil yet to find in the entire basin.
Right now, there are four blocks (Z1, Z2, Z3 and Z4), in the basin, available for bidding. Geologic assessment of the basin indicates these four blocks are located in the favorable potential regions of the basin. Details supporting this evaluation are contained herein. The petroleum potential of each local structure or play depends on its position to certain hydrocarbon sources during geological history and its structural development history as well as fault growth history.
