... of the ground subsidence rate. In order to ascertain the extent of ground subsidence resulting from oil and gas extraction and to consider the impact of creep in rock formations, it was necessary to conduct a comprehensive study. In this paper, we analyse the data from creep experiments on underground shale...

... ABSTRACT Studies have shown that up to 85% of total shale gas-in-place could be adsorbed gas. Thus, how much more adsorbed gas can be extracted will significantly impact the ultimate gas recovery. In recent years, the concept of using thermal stimulation to enhance shale gas recovery has been...
