PORE PRESSURE PLOT

Compactional Pore Pressure analysis  applicable to fine clastics prone sequences

Suitable for these parameters; d-exponent, sonic transit time and resistivity

Normally compacted and over-pressured intervals can be quickly identified on the semi-log plot

The modelled normal compaction trend line (NCT) can be easily manipulated to line up with the observed trend

Pore pressure can be read directly from the plot by means of the ‘Eaton’ overlay

No need to re-draft ‘Eaton’ overlay with each adjustment of NCT – the overlay moves in conjunction with NCT
