The Potentials Prediction of Kradenan and Kesongo Mud Volcano Systems in East Java

Abstract

This is a follow-up study of the Kradenan and Kesongo mud volcano systems which focuses on identifying the potential factors prioritizing the overpressure layer of the Tawun Formation. These systems are located between oil and gas fields that are productive and continuously carry out exploration activities, thereby, posing a high risk to drilling failure and volcanic eruption. Therefore, it is necessary to delineate the potential of the mud volcano system, in accordance with exploration activities to reduce the risk of drilling. The integrate strain ratio, lithostatic and sedimentation rates to map areas were used to for data analysis. The results of this study showed that R1, R2, R8, and R9 are potential to high drilling risks, due to their high lithostatic value which is greater than 7000 psi.
