Fractal Properties of Various Clay Minerals Obtained from SEM Images

Figure 3

Conceptual representation of the adhering of clays to the pore wall surfaces and complicating the intragranular pore space: (a) chlorite (after [65]), (b) chlorite (study area), (c) smectites (image reproduced from the “Images of Clay Archive” of the Mineralogical Society of Great Britain & Ireland and the Clay Minerals Society (https://www.minersoc.org/images-of-clay.html)), and (d) smectites (study area). (e, f) How dissolution holes add extra pores to the reservoir’s pore space (study area). It is worth noting that (b) and (d) are conceptual, not the real magnification of (a) and (c), respectively; however, (f) is the real magnification of (e). On these images, the big pores show the intragranular pore space.
