Geological and Geophysical Survey:
We conduct a comprehensive analysis, which includes an examination of the characteristics of underground rocks. Furthermore, we measure reflected waves induced by artificial seismic vibrations from subsurface structures while ascertaining the presence of geological structures.

Exploration and Appraisal Wells:
We drill exploration wells based on the results of geophysical surveys. If exploratory drilling leads to a discovery, we will drill appraisal wells to confirm the extent and shape of the oil or gas well and the size of reserves.

Evaluation of Reserves:
A comprehensive decision on whether or not to advance to commercial production is made by drawing on the results of appraisal wells.
