oa FTM Revolution: Pioneering Geoscientific Insights in Malaysian AirFTG Data

Malaysia’s geological expanse has both brought incredible success and posed challenges for exploration and resource extraction, often due to the intricate nature of its subsurface. To further enhance these achievements and address the associated challenges, a comprehensive repository of 300,000+ square kilometres of fully processed and interpreted Full Tensor Gravity Gradiometry (FTG) data is available within the region, resulting from data acquisition efforts led by Bell Geospace on behalf of Petronas.

This paper explores the utilization of a novel methodology, Full Tensor Migration (FTM), tailored to extract detailed information from the extensive FTG archive. Initially introduced in 2020 as Source Body Migration and subsequently refined with new techniques in 2023, FTM serves as a rapid, robust inversion technique. Its primary function is to disentangle and extract signal from final processed tensor data, yielding depth interval anomaly maps which are an invaluable resource for exploring within Malaysia’s geological landscape.

The paper underscores the impact of FTM on geological interpretation, with a focus on well-explored Malaysian basins. Through methodological insights and case studies, the authors demonstrate how FTM amplifies signal clarity, heightens depth sensitivity, and streamlines lead generation, providing invaluable support for geological exploration and resource assessment.
