OUTLINES

INTRODUCTION

P1W5 Outcomes & Way Forward Indonesia had conducted sub-surface maping (time structure & depth structure map) and basin modeling. The next step is to estimate hydrocarbon resources of the identified Lead from the depth structure map and to estimate the amount of the hydrocarbon that can be generated from the mature source rock based on 2D basin modeling
