  • Based on the research and optimization of oil and gas resource assessment methods, a comprehensive oil and gas resource assessment method process and technical system, which integrated assessment of conventional and unconventional resources as well as assessment of geological, economic and ecological aspects, were established for SINOPEC-controlled exploration areas during the 13th Five-Year Plan period. The study focused on the key parameters for resource assessment, including a complete hydrocarbon generation-expulsion-retention evolution model and productivity model applicable to different types of source rocks in different basins/regions in China based on TSM basin simulation technology, and a key parameter acquisition method and assessment indicators for resource assessment based on typical calibrated unit dissection. Through systematic assessment of all oil and gas bearing layers (from Sinian system to Quaternary system) of nearly 50 basins/regions in SINOPEC-controlled exploration areas, the geological resources of seven different types of oil and gas, including conventional oil and gas, tight oil and gas, shale oil and gas, and coalbed methane were assessed, which clarified the economical recoverability and environmental impact of oil and gas resources. By studying the resource distribution characteristics, the future exploration areas and directions were further clarified. It is indicated that the deep-ultra deep layers are the main focus for conventional oil and gas exploration, while unconventional resources, especially shale oil and gas, are important areas for increasing oil and gas reserves and production in the future. The sea exploration area also has broad exploration prospects. At the same time, the results of resource assessment provide important basis for the planning and exploration deployment of oil companies during the 14th Five-Year Plan period.
