Rapid burial and high rates of sedimentation in the Malay Basin has lead to development of overpressure by disequilibrium compaction. Overpressure developed by this process can be quantified using industry-standard techniques that rely on porosity/effective stress relationships. However, where thermally-driven secondary processes create overpressure, porosity-based analysis that uses sonic (or seismically-derived velocity data) and resistivity data as a measure of porosity change underestimate
