The Influence of Injected Fluids on Microscopic Pore Structures in the Intersalt Dolomitic Shale Oil Reservoirs

Figure 9

Pore microstructure changes after static evaporation salting out. (a) Clumps of superimposed growth morphology of salt crystals; (b) densely packed salt crystals with no internal permeability; (c) pores partially filled with salt crystals; (d) single-salt-particle dispersion morphology; (e, f) surface-attached layered or flocculent growth morphology of salt crystals.
