WebJun 25, 2015 · Table 1 - Density conversions. For simple, completely homogeneous (single-phase) material, this definition of density is straightforward. However, earth materials involved in petroleum engineering are mixtures of several phases, both solids (minerals) and fluids. Rocks, in particular, are porous, and porosity is intimately related to density. WebJan 13, 2024 · Three different rocks, namely siltstone, sandstone, and coal, collected from a depth below 400 m, were investigated in this study. The results indicated that the proposed method of digital analysis could accurately identify the pore size and porosity values, which were in agreement with the experimental data.
