Project 123.03: 1992 Marine Seismic and Geochemical Survey of Philippine Basins

From March to May 1992, the Australian Bureau of Mineral Resources and the Philippine Office of Energy Affairs conducted a joint marine survey. The project collected 2750 km of 192-channel seismic data, plus geochemical sniffer, gravity, magnetic, and bathymetric data across four offshore basins. The data were acquired using the research vessel Rig Seismic and are intended for petroleum potential analysis.

Use Cases

• Mapping subsurface structures and depocentres based on 2750 km of seismic data.
• Identifying hydrocarbon seepage sources based on geochemical sniffer anomalies and gas composition analysis.
• Analyzing basin geology and petroleum potential by integrating seismic, gravity, magnetic, and bathymetric data.
• Studying the flux rate and composition of hydrocarbon seeps based on vertical geochemical profiles and isotope samples.

Strengths

• Multimodal data collection includes 2750 km of seismic, plus sniffer, gravity, magnetic, and bathymetric data.
• Survey conducted during calm weather, which the description suggests was conducive to collecting low-noise data.
• Data coverage is specified for four distinct basins: NE Palawan Shelf (580 km), Cuyo Platform (730 km), Tayabas Bay (490 km), and Ragay Gulf (950 km).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Seismic data acquisition was limited at night in some areas due to fishing activities, potentially creating gaps.
