They feature complex micro-nano-pore network system, mainly composed of regular primary intergranular pores, dissolved pores, inter-crystalline pores, and micro-fractures. The results show that the Chang 7 tight sandstones are characterized by high clay mineral content and fine grain size. In the present study, mercury injection capillary pressure (MICP) and low-field nuclear magnetic resonance (NMR) are integrated to evaluate the pore size distribution of the Chang 7 tight sandstone reservoir. Pore size distribution characterization of unconventional tight reservoirs is extremely significant for an optimized extraction of petroleum from such reservoirs.

We therefore call for submissions to be included as part of a Special Issue covering the new advances in physical, chemical, and biological processes in energy geoscience, especially for unconventional gases and geothermal energy. In addition, the fluids behaviors of oil, gas, and water in porous media (e.g., coalbed methane, shale gas, and geothermal energy reservoirs) and the associated complex physical, chemical, and biological processes will be particularly important for geo-energy exploration and exploitation together with the carbon capture, utilization, and storage. The formation, occurrence, and flow processes of natural gas in the multiscale reservoirs are becoming new hot research topics. Therefore, unconventional gases (e.g., shale gas, coalbed methane) as low carbon energy accounts for an increasing proportion in the total yields of global natural gas.
The relatively low carbon fossil energy, natural gas, is associated with relatively low emissions of greenhouse gas (i.e., CO 2), which plays an important role in the energy transformation from fossil energy to renewable energy. Since this energy transformation requires a relatively long time and the current associated technologies still need to be updated, the replacement of high-carbon fossil energy with low-carbon energy and renewable energy will be gradual. Strategies to actualize this target include the use of low carbon energy and renewable energy (e.g., geothermal resources), as well as the geological storage and utilization of CO 2. Recently, an increasing number of countries have pledged to cut greenhouse gas emissions in order to prevent the worst consequences of the climate crisis.
