Geoscience data company TGS has partnered with oilfield services firm SLB and Bangladesh government-owned oil company Petrobangla to launch a new multi-client 2D seismic survey programme offshore Bangladesh.

The first phase of the programme involves a minimum programme area of approximately 11,000 line kilometres of new seismic data acquisition.

It aims to provide high-resolution, consistent broadband seismic data on a regional scale to improve the prospective Bengal Fan’s geological understanding.

TGS said the new data would be an essential tool for the evaluation of the acreage and would support the new license rounds under the ‘soon-to-be-revised fiscal terms widely anticipated by the industry’.

In total, the programme will involve acquiring nearly 32,000 line kilometres of multi-client seismic data that will cover most of offshore Bangladesh.

To acquire new data, the partners plan to use long offset and long record lengths to image the deeper sections.

TGS CEO Kristian Johansen said: “This multi-phase seismic program will provide a much-needed regional framework for understanding the Bengal Fan, considered one of the most-extensive remaining unexplored frontier basins remaining in the world.

“Following the successful completion of our extensive East Coast India 2Dcubed reprocessing project, we continue to provide a seismic-fuelled boost across the Bay of Bengal to support offshore exploration in this region and augment licence round decision-making.”

The partners plan to start the acquisition in early January 2023. Final processing is expected in Q1 2024. 

In November 2022, TGS started a 3D data reprocessing programme offshore Uruguay. The programme comprises 25,000km², covering blocks in the active Uruguay Licencing Round.
