The exploration process begins with geological mapping, where geology experts use geological and geophysical data to identify areas that may potentially contain oil. They study the geological characteristics of rocks, structures, and lithology in the exploration area to understand the potential for oil reserves.

Geophysical studies involve the use of advanced technologies such as seismic mapping, gravity, magnetic, and electromagnetic surveys to collect data on the geological structures and oil potential within the Earth. This geophysical data is analyzed to identify potential locations where oil may be present.

After potential locations are identified, the exploration team will collect samples of soil, rocks, and water from the exploration area for testing in laboratories. Testing these samples provides further information about the potential oil resources, including the type of oil, chemical composition, and estimated volume that may be present.

After collecting and analyzing geological, geophysical, and sample testing data, the exploration team will conduct economic evaluation to determine the economic potential of the discovered oil field. This involves cost and benefit analysis, market price projections, and calculation of potential profits that can be obtained from the development of the oil field.

If the oil field is deemed economically viable, the next stage in exploration is to conduct exploration drilling to confirm the presence of oil within the Earth. Exploration drilling is carried out using specialized drilling equipment to reach the layers that potentially contain oil.

The data collected during the exploration process is thoroughly analyzed, and decisions are made based on the findings and evaluation results. These decisions may involve further exploration activities, development plans, or investment decisions for the oil field.
