Further evaluation of source rocks in eastern Tarim Basin

The studies of organic abundance, type and maturity of source rocks from wells in the eastern Tarim Basin showed that the Middle-Lower Cambrian source rocks were the most favorable source rocks in the study area. The organic abundance was high, with the average TOC content higher than 1.0%. The organic type was good, generally type Ⅰ-Ⅱ₁. The organic maturity was high, with Ro ranging from 0.88% to 2.75%, indicating for high-mature and over-mature stages.
