Although the Cambrian marine shale in the Tarim Basin is usually considered to be the source rocks for overlying conventional reservoirs, its unconventional shale-gas potential has not yet been evaluated. To indicate the unconventional resource play potential and highlight more favorable zones, we conducted a comprehensive lithologic, petrophysical, and geochemical analysis of 228 drill core samples from 14 wells and 167 outcrop samples from eight geologic sections in the basin. The results indicate that the Cambrian marine shale was deposited in (...)
