TGS, a global leader in energy data and intelligence, announces the expansion of its multi-client seismic coverage in the Malay Basin with the Peninsular Malaysia 3D Mega Merge Stage 4 Reprocessing project. 

TGS is reprocessing legacy 3D datasets to improve subsurface clarity and provide a consistent, basin-wide view of the Malay Basin. The use of uniform technology and workflows across all stages helps operators gain faster exploration insights.

Stage 4 extends the regional dataset by reprocessing and merging approximately 16,000 square kilometers of legacy 3D seismic data covering key exploration blocks relevant to upcoming Malaysia Bid Round (MBR) opportunities. MBR is an annual licensing round hosted by Malaysia Petroleum Management and PETRONAS, offering a range of opportunities, from exploration blocks and discovered resources to mature assets and technical studies, allowing investors to grow their energy portfolios. 

Building on earlier phases, the project supports growing exploration interest in the Malay Basin by improving data quality and accessibility. This has been proven by recent discoveries within the basin. 

The project, undertaken in collaboration with our joint venture and processing partner, DUG, utilizes broadband processing, full-waveform inversion, and pre-stack depth migration to enhance imaging of deeper targets and complex structural settings. Together with the continuous, basin-wide view achieved across all Mega Merge stages, operators gain a ready-to-license dataset for rapid screening, lead identification, and more confident prospect evaluation without the lead time of new acquisition. 

“This latest phase of the Mega Merge project strengthens our commitment to deliver high-value regional coverage to accelerate exploration across Peninsular Malaysia,” said David Hajovsky, Executive Vice President of Multi-Client at TGS. “By modernizing legacy surveys and applying consistent imaging across phases, we help operators move from basin screening to decisions with greater confidence and speed.”

The multi-client model offers a cost-effective entry point for companies preparing for near-term licensing while maintaining continuity with prior Mega Merge deliverables. The integrated result supports basin-wide analysis, consistent attribute interpretation, and streamlined prospect maturation.
