Viridien announces new geologic study to evaluate prospectivity of frontier Langkasuka basin offshore Malaysia

Paris, France | Oct 21, 2025

Viridien, in collaboration with Malaysia Petroleum Management (MPM), PETRONAS, is completing an integrated geological study designed to provide new prospectivity insights into the underexplored Langkasuka Basin, located within the Malacca Strait offshore area to the west of Peninsula Malaysia. The insights generated will provide explorers with a competitive advantage by better informing their licensing and investment decisions.

The 38,000 sq km study is scheduled for delivery in November 2025. 

Multi-disciplinary technical experts from Viridien’s Earth Data team have leveraged the company’s recent Selat Melaka multi-client 2D seismic dataset and data-rich GeoVerse geological database to create innovative methodologies that address and overcome the unique challenges of this basin, delivering unparalleled insights into the unexplored Paleozoic interval. 

Dechun Lin, Head of Earth Data, Viridien, said: “Viridien is committed to providing comprehensive geoscience solutions that support the industry in better understanding the prospectivity of attractive frontier basins. This study will enable confident, data-driven exploration decisions in Langkasuka and adjacent basins in the region.”
