With continuous and progressive burial, a sandstone enters the intermediate burial zone at approximately 80°C (zone of intense diagenesis, 80 to 110°C Table 1). In this interval, a potential hydrocarbon reservoir accommodates important porosity enhancing reactions early-formed carbonate cements may be dissolved (or later carbonate cements inhibited), and aluminosilicate framework grains (both feldspar and lithic) may be dissolved. Thus, in this zone, porosity can be preserved or significantly enhanced.
