Abstract
Gravity surveys have played an essential role in many geoscience fields, especially as an early screening tool for subsurface hydrocarbon exploration. Since land-based gravity surveys are often expensive and difficult to obtain in remote places, we explore the use of satellite-derived gravity data which is available throughout the Earth and updated periodically. Since the accuracy and resolution of the gravity measured from satellites are lower than land-based gravity measurements, the satellite-based data was enhanced through a deep-learning-based super-resolution (SR) technique. The SR-enhanced Bouguer and free-air gravity anomaly data were used for the classification of hydrocarbon regions using supervised machine learning. Results indicate the successful application of supervised machine learning for hydrocarbon classification using SR-enhanced Bouguer and free-air gravity anomalies with high prediction accuracy.
