The mineralogy and texture of mudrocks from the Malay Basin have been measured to understand the extent to which diagenetic processes drive porosity loss in shales. Previously, sonic and density log data from wells in the region highlighted the possible role of chemical compaction in reducing porosity with permeability and contributing to elevated pore pressures at depth. This study finds change in mudrock properties can be seen in samples from below the interval associated with the onset of chemical compaction and would provide a logical mechanism behind log behaviour.
