///In order to deal with the deviation between the recoverable reserves calculation result and the actual value, volumetric method was used for calculating CBM resources, adsorption coefficient method and adsorption isothermal curve formula method were used for revising the result of volumetric method, CBM recoverable resources of Shanxi Formation and Taiyuan Formation of Liulin Block were estimated. Based on the above efforts, the recoverable CBM potential of Liulin Block is resolved and solid foundation is established for compiling development program and determining the investment in the future.
