Summary Considerable tight oil resources in China accumulate in carbonate rocks. Due to their individual differences, targetoriented seismic characterization is performed from logbased petrophysical analysis and data mining to seismic inversion and quantitative description. The objective of this study is to map tight carbonate reservoir properties and provide technical support to drilling site deployment. Introduction Tight oil resources in China may mainly occur in Triassic, Jurassic, Cretaceous, and Eocene sandstone and Permian, Jurassic, Cretaceous, and Paleogene carbonate rocks; the former has been found in the Ordos, Songliao, Tarim, Sichuan, Bohai Bay Basins, etc. and the latter found in the Junggar, Sichuan, Bohai Bay Basins, etc. (Jia et al., 2012; Du et al., 2014). More than one third of tight oil resources have been discovered to turn up in carbonate rocks.
