OIL AND GAS EXPLORATION
PT Geoscan Eksplorasindo plays a crucial role in the initial stages of oil and gas exploration, providing our clients with vital subsurface data to de-risk their projects. We utilize a combination of non-invasive and high-tech survey methods to effectively map potential hydrocarbon basins.
Our services for the oil and gas sector include:
Passive Seismic Surveys
This is a non-intrusive and cost-effective geophysical method. Instead of using artificial energy sources, we measure naturally occurring seismic energy (micro-tremors) from the Earth’s interior to create detailed subsurface structural maps. This technique is particularly useful for initial regional-scale mapping and identifying potential geological structures that may contain oil and gas.
Remote Sensing Analyses
Our team performs detailed analyses of satellite imagery and other remotely sensed data. This allows us to identify surface geological features, structural lineaments, and other indicators that can help narrow down target areas for further exploration.
Aeromagnetic Surveys
We use airborne surveys to measure tiny variations in the Earth’s magnetic field. This data helps us to map the depth and structure of the magnetic basement rock, which is a key factor in identifying sedimentary basins with potential for hydrocarbon deposits.
“PT Geoscan Eksplorasindo’s Oil and Gas Exploration experience provides a strong foundation for maximizing value and minimizing exploration risks.”

This image shows a sample of the passive seismic survey results we conducted. The primary goal of this survey is to identify and predict areas with potential for hydrocarbons below the surface. The data presented illustrates spectral anomalies from the Earth’s natural micro-tremors, which serve as indicators of oil and gas accumulations. This visual result acts as an invaluable tool for our clients, helping them to reduce exploration risk and make more informed decisions before drilling.
We utilized both Induced Polarization (IP) and Resistivity surveys to effectively map the area. Resistivity data provided crucial information on the different rock types and geological structures, while the IP survey was instrumental in identifying the chargeable ore body.
