Sandstone porosity prediction is a matter of estimating original composition and subsequent diagenesis. Use the table below to predict sandstone porosity.
Sandstone porosity prediction is a matter of estimating original composition and subsequent diagenesis. Use the list below to predict sandstone porosity.
# Estimate the original composition of the sandstone from provenance (use Figure 9-55) and depositional environment.
# Estimate the effects of near-surface diagenetic processes (see Figure 9-56).
# Estimate the effects of mechanical diagenetic processes (see Figure 9-57).
# Estimate the effects of intermediate and deep burial diagenesis, especially with respect to the creation of secondary porosity.
# Using information collected in steps 1 through 4, predict the final porosity ranges using burial history (next procedure).
