Professor Ma’s research has centred on marine carbonate hydrocarbon geology, deep-basin gas systems, and exploration of large gas fields, with particular emphasis on the Sichuan and Tarim basins. Through leadership of major petroleum exploration programmes, he contributed to the discovery and development of the Puguang supergiant sour-gas field in the Sichuan Basin, one of China’s major marine carbonate gas fields, and subsequently participated in exploration leading to the discovery of the Yuanba and Fuling gas fields. These projects have contributed to the expansion of China’s natural gas resource base and to the development of exploration technologies for deep marine carbonate and shale-gas systems. Author of numerous peer-reviewed publications and monographs, Professor Ma has received multiple National Science and Technology Progress Awards for his research and exploration work. Through sustained engagement in petroleum geological research, resource exploration, and large-scale energy projects, his work has contributed to connecting advances in petroleum geology with practical applications in natural gas exploration, resource assessment, and energy-resource development.
