Philippines Marine Seismic Survey 1992: Seismic, Sniffer, Gravity, and Magnetic Data

Four Philippine offshore sedimentary basins were surveyed from March to May 1992 by the Australian Bureau of Mineral Resources and the Philippine Office of Energy Affairs. The project collected 2750 km of 192-channel seismic data, plus geochemical sniffer, gravity, magnetic, and bathymetric data. The newly acquired data were to be processed and integrated with existing industry data to analyze petroleum potential.

Use Cases

• Mapping subsurface geological structures based on 2750 km of seismic reflection data.
• Identifying hydrocarbon seepage anomalies based on geochemical sniffer data and gas composition analysis.
• Analyzing basin geometry and depocentres based on ship-board seismic monitor observations.
• Integrating gravity and magnetic data with seismic interpretations for regional geological modeling.

Strengths

• Multimodal data collection includes 2750 km of seismic, plus sniffer, gravity, magnetic, and bathymetric data.
• Survey covered four distinct basins with specific line-kilometer totals provided (e.g., 950 km in Ragay Gulf).
• Weather conditions were described as very calm, which is conducive to collecting low-noise data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
