Abstract: Coalbed gas content is one of important parameters for coalbed methane (CBM) resource estimation, favorable area evaluation and well deployment. It is related to many factors and difficult to predict. This paper focuses on Baode south survey in the north of the eastern Ordos basin. According to the cross plot of logging data and real gas content of coal core, the density of coal bed is the most relevant factor of gas content, and the relationship between them is derived. Combined with the research of 3D seismic data, the density data and the coal density attribute are obtained by pre?stack simultaneous inversion, and then the lateral distribution of coalbed gas content is predicted quantitatively. The technique applied in the Baode south survey in the north of the eastern Ordos basin for quantitative coalbed gas content prediction can support the research of the coalbed gas content for the favorable area evaluation and the well deployment
