WebNov 1, 2024 · Various multi-physics models have been put forth in the literature to forecast the apparent permeability of gas in shales and ultra-tight formations. However, a means of accurately describing the relative contributions of physics in multiscale remains a challenge. Webpermeability of rock causes the gas to trap and prevent it from migration. The gas trapped in such formations in the form of absorbed organic material or trapped in tiny pores of rock. While considering gas potential, apart from permeability other properties of shale are total organic content (TOC) and thermal maturity.
