Selat Melaka 2D survey

The Selat Melaka 2D survey (data in purple) located in the Langkasuka Basin of Peninsula Malaysia provides the industry with 7,197 km of high-resolution seismic data in a frontier area that previously lacked data coverage.

Viridien and Petronas, via Malaysia Petroleum Management (MPM), are working on a geological study of the little-explored Langkasuka Basin in the Malacca Strait offshore area west of Peninsula Malaysia. 

The 38,000-sq-km study is due to be completed next month, with results available to E&P companies considering licensing/investment both in Langkasuka and adjacent frontier basins.

Viridien said its Earth Data team has used the company’s Selat Melaka multi-client 2D seismic dataset and GeoVerse geological database to develop methodologies that address the basin’s challenges.

This has led to fresh insights into the unexplored Paleozoic interval.
