PGS reprocesses data offshore Indonesia

PGS’ has launched the North Sumatra MC2D data rejuvenation project to provide new insights into ‘one of the hottest hydrocarbon provinces in Indonesia’ after the successful Timpan-1 discovery in 2022.

Latest 7700 line km PSDM reprocessing and regional-scale data coverage will allow for better understanding of basin development history and play analyses, to give improve insights of existing and new petroleum systems.

PGS’ North Sumatra MC2D covers both existing discoveries and open blocks, enabling seismic well ties and correlations into frontier areas for better mapping of play fairways. This will provide confidence for future licensing opportunities of these open blocks, said PGS.

Data rejuvenation workflows are built on the knowledge acquired by PGS during the North Sumatra MC3D project in the same basin. Processing will include 2 ms, high-resolution, broadband processing and depth conversion, based on full waveform inversion.

‘The goal of the North Sumatra MC2D project is to address the challenges associated with imaging the deeper pre- and syn-rift package, which host both source and reservoir rocks. The higher-resolution imaging will also address challenges linked to fault imaging and hydrocarbon migration pathways,’ said Alex Vartan, VP

Asia Pacific at PGS. Data will be ready in Q2 2024.
