Gravitational Compaction and Pressure Solution

The analysis of the development of porosity reveals the same situation as outlined above. In the upper sandstone horizons down to 2.5 km it drops gradually from 190 m per 1% to 85 m per 1%. Belowthis it increases to reach 500 m per 1% at a depth of 4.2 km. 

The density gradients have been established in the same way and reveal the same trends for the compaction of the section as those of the porosity.
