Fractal dimensions of shale
WebSep 1, 2024 · The types and geometric shapes of pores are related to the fractal dimension. The complexity of pore structure increases with an increase in the fractal dimension. In addition, shale having undergone H 3 hysteresis (Y-1) have higher fractal dimensions than those having undergone H 2 hysteresis (Y-4). Thus,slit-shaped or … WebThe occurrence and flow of shale gas are substantially impacted by nanopore structures. The fractal dimension provides a new way to explore the pore structures of shale reservoirs.
