EVALUATION OF THERMAL PROPERTIES AND LOG MOTIFS OF WELLS IN CENTRAL MALAY BASIN

Malay Basin is a result of complex tectonic mechanism shaped by 3 major tectonic events that give rise to the current structure in the basin; 1) Extension during Late Cretaceous to Early Miocene, 2) Thermal subsidence during Early Miocene to Middle Miocene and 3) Compression during Late Miocene to Pliocene. The targeted formations of this study are S, J and T fields. Pinnacle of this study in revolving around the petrophysical information and reservoir characterization with added minor study on Kelantan Delta environment could be a potential information through the comparison of the modern environment and historical environment of Malay Basin.
Interpretation of gamma ray, field mapping, geological experiment, profiling data of various variables corresponding to the thermal conductivity such as porosity, volume of shale and temperature is calibrated with the well log to find the empirical relationship between thermal conductivity and depositional environment which will be conducted in an attempt to better understand the unfolded story of the specific petrophysical data of Malay Basin with comparison to the modern environment of Kelantan Delta. Extended period of time, methods of better accuracy and more extensive study are recommended for future works in enhancing the understanding and knowledge about the reservoir characterization of several fields in Malay Basin mainly.
