TGS setting the stage for Malaysia’s future licensing rounds

News Digest (www.upstreamonline.com)

Project Overview and Objectives

TGS is undertaking the Peninsular Malaysia 3D Mega Merge Stage 4 Reprocessing project to expand its multi-client seismic data coverage in the Malay basin. The primary objective is to reprocess approximately 16,000 square kilometres of legacy 3D seismic data. This initiative aims to enhance subsurface clarity and provide a consistent, basin-wide perspective, supporting a current exploration renaissance in the region. By applying uniform technology and workflows across all project stages, TGS enables operators to gain faster exploration insights.
Strategic Importance and Connection to Licensing

The reprocessed data specifically covers key exploration blocks that are relevant to the upcoming Malaysia Bid Round (MBR). The MBR is an annual licensing round hosted by Malaysia Petroleum Management and Petronas, typically held in the first quarter. It offers a range of opportunities, including exploration blocks, discovered resources, mature assets, and technical studies, allowing investors to expand their energy portfolios. This project builds upon earlier phases to support growing exploration interest, a trend validated by recent discoveries within the basin.
Technical Methodology and Data Enhancement

The project is being conducted in collaboration with joint venture and processing partner DUG. It employs advanced techniques, including broadband processing, full-waveform inversion, and pre-stack depth migration. These methods are designed to significantly improve the imaging of deeper geological targets and complex structural settings. The integration of data across all Mega Merge stages results in a continuous, basin-wide view.
Benefits for Operators and the Multi-Client Model

Operators gain access to a ready-to-license dataset that facilitates rapid screening, lead identification, and more confident prospect evaluation, eliminating the lead time associated with new seismic data acquisition. The multi-client model provides a cost-effective entry point for companies preparing for near-term licensing rounds while ensuring continuity with previous project deliverables. The integrated final product supports comprehensive basin-wide analysis, consistent attribute interpretation, and a streamlined process for prospect maturation.
