definite reservoir-rock properties. These groups were identified by means of com-
parison with the well-testing results. An example of identification of beds and a
measure of their subdivision into groups (correlation coefficient or generalized Eu-
clidian distance) were used by Buryakovsky et al. (1990).
The fS o (see Eq. 11.103) of reservoir rocks was evaluated by simulating processes
of compaction and other diagenetic changes of sediments, as described above. Ex-
amples of simulation of reservoir-rock properties are presented in Table 11.13 (or in
Fig. 11.36).
