ABSTRACT
The conventional AVO attributes have the ambiguity to detect hydrocarbon especially in the tight reservoir for its extremely low porosity. The aim of this paper is to find a best sensitive attribute to pore fluid in tight reservoir to reduce the uncertainty of hydrocarbon prediction via the integration of Monte Carlo simulation and AVO attributes. It gives the key step of method and applied the method to predict gas reservoir from Sichuan Basin of China, the test result shows that it can provide more reliable evidence of suggestion for development wells.
